An audiophile, from Latin audire "to hear" and Greek philos "loving," can be generally defined as a person dedicated to achieving high fidelity in the recording and playback of music [1] [2].

Contents

[edit] Audiophile beliefs

Audiophile values may be applied at all stages of music reproduction—the initial audio recording, the production process, and the playback, which is usually in a home setting. High end is expensive, high-quality, or exotic products and practices used in the reproduction of music. There is much skepticism inside and outside the audiophile community as to which practices and products have discernible or measurable effects on the listening experience. Those skeptical of the benefits achieved with exotic or fanciful equipment setups are generally referred to as objectivists.[citation needed] People who set up customized audio playback systems according to personal tastes are generally referred to as subjectivists.[citation needed] People on both sides of the debate concede that because many audiophiles are laymen and lack technical knowledge, they are vulnerable to exploitation by fanciful, nebulous, and outrageous claims made by unethical equipment vendors. Audiophool is a derogatory term sometimes used by objectivists to refer to what they see as gullible audio consumers willing to spend a great deal of extra money in imperceptible or unnecessary system-performance gains. There is a tremendous variety and price range of audio equipment available. Actual scientifically measurable audio-equipment performance figures are often omitted or obscured from advertisements and user-review literature in favor of vague notions of style, power, fidelity, durability, etc. that would not be discernible or evident to most listeners.

One statement that has influenced some subjectivists' values is from Harry Pearson, longtime editor of The Absolute Sound:[1]

"We believe that the sound of music, unamplified, occurring in a real space is a philosophic absolute against which we may judge the performance of devices designed to reproduce music."

Audiophiles widely share the belief that even the world's best music-reproduction equipment currently falls far short of this ideal.[citation needed]

Even given agreement on the goal, opinions vary widely among designers and listeners on how best to achieve it. If there is one shared design principle, it is minimalism.[citation needed] Given that capturing, storing, and playing back music inevitably degrades it, the fewer and simpler the stages, the better.[citation needed] Audiophile gear, for example, almost universally lacks tone control circuits, since it is felt that these can only degrade the audio quality while moving the sound away from the ideal.[citation needed]. The minimalist subjectivist assertion is that music contains elements that cannot be measured by an electronic instrument,[2]so the less one alters the original signal, the more likely it is that that unmeasurable quality can be preserved. Thus subjectivists believe that objective measurements are irrelevant or misleading.

Objectivists, however, want to reasonably quantify and specify the effects of input source, amplifier setup, system power, speaker configuration, etc. on the listening experience and is thus complementary to purely subjective preferences in quantifying the perceptible effects of different equipment setups.

Subjectivists and objectivists agree that the room in which the playback system works is of great importance to the sound quality. There are a wide variety of room-treatment products available to address this issue, and extreme audiophiles are known to use purpose-built listening rooms.

[edit] Consumer practices

[edit] Sound sources

Audiophiles regularly listen to music from compact discs (CDs), records, and frequency-modulation (FM) radio. Since the early 1990s, CDs have become the most common source of high-quality music, destroying the mass market for records. Due to hobbyist record collectors, the extensive back-catalogue of music on records not available on CDs, and the perceived better sound quality of records among many subjectivists, records remain popular among a minority of listeners. The debate is particularly sharp in this area, with analog proponents claiming a warmer analog sound and loss of information in the sampling process in digital sound, while digital proponents decry analog formats as lacking dynamic range and having greater deviations in frequency response and distortion. Nevertheless, turntables, tonearms, and cartridges are among the most exotic and lavish high-end audio products available today, despite the difficulties of keeping records free from dust and the rather physically delicate setup associated with a turntable.

The 44.1 kHz sampling rate of the CD format, in theory, restricts CDs' information losses to above the theoretical upper-frequency limit of human hearing of approximately 20 kHz (see Nyquist limit). It should be noted that typical audiophiles are in their thirties or older [3] and highly unlikely to be able to hear beyond 18 kHz. Some critics argue that there are still deleterious effects on the sound quality at this sampling rate. Newer formats such as DVD-Audio and Super Audio Compact Disc (SACD) with sampling rates of 96 kHz or higher have been developed in an attempt to address this criticism. This issue of sample rate again illustrates the difficulty of accurately and consistently measuring and predicting listener response and preference of audio playback technology.

Despite the popularity of MP3 digital audio players such as iPods, some audiophiles criticize these devices because of their reliance on lossy data compression, for example in MP3 encoding; musical information is lost in proportion to the degree of compression. Audiophiles who use a digital audio player will often encode their music at higher bit rates to maintain sound quality at acceptable levels for casual listening. However, many digital audio players can also accept uncompressed formats such as WAV (PCM), foregoing compression in order to retain full quality. Some players also allow lossless compression algorithms which can compress audio files without degrading their sound quality. Popular lossless formats include FLAC, WavPack, Monkey's Audio (APE), Apple Lossless, True Audio, Windows Media Audio 9 Lossless, and Shorten.

While many digital-audio devices have integrated converters, a healthy demand exists for after-market digital-to-analog converters.

[edit] Amplifiers

Many audiophile systems separate the functions of the preamplifier, which selects audio signals and has a volume control, and the power amplifier, which takes a line-level audio signal and drives the loudspeakers. Some audiophiles use two monophonic power amplifiers in a 'monoblock' configuration rather than one stereophonic power amplifier. Some use no preamplifier, instead connecting a CD player with a variable output directly to a power amplifier. Some go even further and use multiple amplifiers per loudspeaker to drive the woofer, midrange, tweeter, etc. The terms bi-amped and tri-amped are sometimes used to describe these systems. There are, however, those who advocate using integrated amplifiers that combine a preamplifier and power amplifier in one box, arguing the benefits of minimalism.

Audiophile amplifiers are available based on solid-state (semiconductor) technology, vacuum-tube (valve) technology, or hybrid technology—semiconductors and vacuum tubes. Very low power single-ended triode tube amplifiers are often claimed to provide superb sound when paired with appropriately sensitive loudspeakers. On the other hand, there are others who use solid-state amplifiers rated at over 1,000 watts RMS per channel. Some subjectivists believe that tube amplifiers, despite their much higher distortion, produce a more faithful and detailed reproduction in comparison to solid-state amplifiers. Objectivists respond that this is largely a matter of opinion and personal taste, not proper reproduction of sound. Tube amplifiers, however, are heavily used in music production, primarily in guitar amplifiers because of their soft clipping when overdriven, compared to solid-state circuitry.

[edit] Loudspeakers

Audiophile loudspeakers use a wide variety of technologies and range greatly in size and cost. The availability of high-priced, exotic designs is most extreme in the loudspeaker category. It is possible to spend more than $100,000 USD on a pair of high-end loudspeakers. Starting at prices well under $500, budget audiophile loudspeakers are also widely available, and are often the beneficiaries of more advanced technologies developed for higher priced flagship designs.

In contrast to consumer oriented audiophile speakers, monitor speakers used by professional audio engineers are usually relatively modest in size and price.

The cabinet the speaker is made from is referred to as the enclosure. There is a wide variety of loudspeaker enclosure designs, including sealed, ported, transmission line, infinite baffle, horn loaded, and aperiodic.

The drivers are the actual sound-producing elements, commonly referred to as tweeters, midranges, woofers, and subwoofers. Driver designs include dynamic, electrostatic, magneplanar, ribbon, planar, ionic, and servo-actuated.

The direction and intensity of the output of a loudspeaker, called dispersion or polar response, has a large effect on its sound. Various methods are employed to control the dispersion. These methods include monopolar, bipolar, dipolar, 360 degree, horn, waveguide, and line source. These terms refer to the configuration and arrangement of the various drivers in the enclosure.

[edit] Accessories

Audiophiles use a wide variety of accessories and fine-tuning techniques, known as "tweaks", to improve the sound of their systems. These tweaks include: filters to clean the electricity, equipment racks to isolate components from room vibrations, power cables, interconnect cables (e.g. between preamplifier and power amplifier), high quality speaker cables and stands (and footers to isolate the speakers from the stands), as well as and room treatments, to name but a few. Among the most controversial of these tweaks are expensive, high-end shielded audio cables used for electrical power, line-level, loudspeaker, and digital-signal connections.

Room treatments typically consist of sound-absorbing materials placed strategically within a listening room to reduce the amplitude of early reflections. Room treatments can be expensive and difficult to optimize, but are considered by many to be the least "tweaky" of the many available tweaks, because their effectiveness is easily measured and grounded in verifiable science. Many tweaks do work and much of the fun of the hobby is to "squeeze" even more performance out of an otherwise excellent sounding component.

[edit] Headphones

Another, less expensive, practice of some audiophiles is the use of premium headphones. While sometimes outlandish in price (as high as $10,000), most headphones marketed to audiophiles are a tiny fraction of the cost of comparable speaker systems, and do not require any room adjustment for music enjoyment. Well-known high-end headphones are considered to offer audiophile quality for prices well under a thousand dollars. Some feel that the performance of high-end headphones is improved by the use of dedicated headphone amplifiers and cables. Newer canalphones, while as expensive as their larger counterparts and considered more limited in soundstage and other characteristics, can be driven by less powerful outputs like portable devices, and are increasingly used by audiophiles.

[edit] Professional practices

Audiophiles tend to hold commercial-music recording practices in low regard.[citation needed] Particularly in the pop-music domain, most recordings are based on the heavy use of multitrack technology, the studio dominated by a huge mixing board with as many as eighty channels, each channel operating in the digital domain and subjected to a wide variety of tonal and "effects" processing. Audiophiles believe that this complex signal chain degrades the quality of the signal and lessens the spontaneity and integrity of the musical performance.[citation needed] Audiophiles also criticize the heavy dynamic-range compression found in many pop music recordings. There are some professional musicians and audio engineers who agree; currently active recording artists who use minimalist audiophile recording techniques include Neil Young and the Cowboy Junkies among many others.

Techniques applied by audiophile recording engineers include the use of exotic high-end microphones, the use of fewer rather than more microphones, specific microphone placement, the use of tube-driven rather than solid-state electronics, and the use of a minimal amount of processing in the production chain.

[edit] Current trends

Audiophile's home theatre
Audiophile's home theatre

In terms of revenue, the mainstream electronics business is now dominated by multi-channel home theater rather than two-channel stereo sound. Almost every major vendor has introduced a full line of home-theater products, even those who traditionally eschewed such products. The degree to which this phenomenon has happened varies from country to country. It is probably most advanced in the United States, and less so in the United Kingdom and other countries.[citation needed] Audiophiles and non-audiophiles alike still buy high quality two channel systems as well as incorporating large floorstanding loudspeakers into their surround-sound system.

Audiophiles are interested in newer higher-bandwidth digital-recording formats such as SACD and DVD-Audio. These formats encode music at data rates of 24-bit / 96 kHz or even 192 kHz compared to 16-bit / 44.1 kHz for CDs, and thus are referred to as high-resolution audio formats. Because manufacturers have failed to agree on a single format, because there are relatively few releases in these formats, and possibly also because audiences consider CDs to be good enough as is, acceptance so far has been limited. The improvements offered by these higher-resolution formats requires the use of specialized hi-fi equipment with a correspondongly higher cost, which has so far failed to achieve wide market acceptance. The continued refinement of the standard CD audio technology, at both the recording/production and playback stages have created ever higher-quality DACs, analog stages, and upsampling features that have elevated the standard CD to very high levels.

[edit] Objective versus subjective

Objectivists believe that audio components, accessories, and treatments must pass rigorously-conducted double-blind tests and meet specified performance requirements to meet the claims made by their adherents. Subjectivists, however, believe that careful individual listening is an appropriate tool for discovering the true worth of a device or treatment, and will generally acquire equipment that suits their own listening or style preferences as opposed to measurable equipment performance.

[edit] Objectivists' criticisms of subjectivism

  • Every properly conducted and interpreted double-blind test has failed to support subjectivists' claims of significant or extremely subtle sonic differences between devices if measurements alone predict that there should be no sonic differences between the devices when listening to music[3] [4].
  • Listening tests are subjected to many variables, and results are notoriously unreliable. Thomas Edison, for example, showed that large audiences responded favorably when presented both live performances by artists and reproductions by his recording system,[4] which today would be regarded as primitive in quality.
  • Similarly, results of component evaluation between various listeners or even the same listener under different circumstances cannot be easily replicated or standardized.
  • Measured-audio distortion is immensely higher in electromechanical components such as microphones, turntables, tonearms, phono cartridges, and loudspeakers than in purely electronic components such as preamplifiers and power amplifiers, making it logically more difficult for objectivists to accept that very subtle differences in the latter can have an appreciable effect on overall musical reproduction quality.
  • Similarly, the acoustic behavior of the listening room—the interaction between loudspeakers and the room's acoustics—and the interaction between an electromechanical device (loudspeaker) and an electronic device (amplifier) are subjected to many more variables than between electronic components. Thus the "difference" in sound quality between amplifiers is actually the ability of an amplifier to interface well with loudspeakers or a lucky combination of loudspeaker, amplifier, and room that works well together [5].
  • It is difficult, but very important, to match sound levels before comparing systems, as minute increases in loudness—more than 0.1dB—have been demonstrated to cause perceived improvements in sound quality.[citation needed]
  • Subjectivists often reject attempts to categorize differences in sound using measurements, despite strong evidence of its effectiveness, for example the work of audio engineer Bob Carver, who has shown that by tailoring the transfer function of a particular amplifier, he was able to make it sound indistinguishable from another [6] [7].
  • Solid-state amplifiers are often not used for guitars due to the harsh sound created by an overdriven solid-state amplifier compared to valve. In the high fidelity debate, subjectivists often prefer vacuum-tube electronics over solid-state electronics, because despite inferior measured performance, the subjectivists claim a warmer or more musical sound. Vacuum-tube amplifiers are often attacked as inferior because, in addition to their substantially higher total harmonic distortion, they require rebiasing, are less reliable, generate more heat, are less powerful, and are often more expensive.[5]
  • Subjectivists regularly make strong claims for the allegedly superior quality of analog music reproduction from records played on turntables compared to digital music reproduction from CDs played on CD players despite digital music's absence of clicks, pops, wow, flutter, audio feedback, or rumble. Digital also has a higher signal-to-noise ratio, has a wider dynamic range, has less total harmonic distortion, and has a flatter and more extended frequency response.[6][7]
  • Some audiophile-equipment designers and consumers are obsessed over seemingly irrelevant details. Many components, for instance, are able to reproduce frequencies higher than the limit of human hearing—20 kHz.[8] Some sources, such as FM radio, will not reproduce frequencies higher than 15 or 16 kHz.
  • Some subjectivists' practices seem driven by fashion, e.g., the late eighties' vogue for marking the edges of CDs with a green felt marker[9] or suspending cables above the floor on small racks, and bear no relation to well-known laws of physics.
  • Notwithstanding benefits, some audiophile products’ prices strain credulity: at the ultra-high end, it is possible to spend over a hundred thousand dollars for loudspeakers, tens of thousands for amplifiers and CD players, and more than a thousand dollars for a power cable [8] [9].
  • Some vendors of products destined for the most obsessed audiophile make fanciful and unscientific claims for their products. Tice Audio, for example, once sold what appeared to be an ordinary clock radio which, it was claimed, would change "electron energy levels," thereby improving the quality of a playback system if plugged into the same electrical circuit.[10] PWB Electronics [10] markets pebbles which are claimed to improve sonic performance when placed anywhere in rooms where audio components are present.
  • Many vendors of audio cables make outrageous claims for alleged improvements in sound quality. Nordost [11], for example, makes claims as to the transmission speeds of their cables and the purity of the copper used to justify prices of several thousands of dollars per metre for their "reference products." Some audio cables are filled with oil or water, glow in the dark, or come with a separate AC cord which must be plugged in to power the cable. Some have such lavish appearances that to the connoisseur of cables, they can be considered audio jewelry.[11]
  • Some subjectivists' claims, while superficially based on accepted physical principles, apply them to circumstances where they are irrelevant. The skin effect, for instance, which relates the efficiency of cables to the frequency transmitted, is often applied to audio frequencies where it is insignificant [12].
  • Many of the most outspoken subjectivists, including reviewers, columnists, and "pundits," lack engineering training, technical knowledge, and objective credentials, and most will fully admit a lack of understanding as to the technical merits of what they are analyzing, but nevertheless praise a product's innovation and performance [13] based on perceptual jargon.
  • Counterintuitively, subjectivists claim, but cannot substantiate, that loudspeaker (and indeed any other) cable is directional, giving better sonic performance in one direction.
  • Subjectivists often claim that home-theater sound is inferior to high-fidelity sound, even though double-blind tests have shown that this is wrong. Many subjectivists believe that the sound from records is superior to the sound from home theater. Subjectivists often look down on home-theater sound even though many subjectivists accept FM radio as high fidelity [14] [15].
  • The majority of audiophiles are men over 35[citation needed], which is the part of the population with the worst hearing. Men have worse hearing than women,[12] and hearing worsens irreversibly with age.

Overall, the subjectivists' world is looked upon by objectivists as being a hotbed of gullibility and fraud, its marketing engine driven primarily by either a constant desire for one-upmanship or a more benign desire to tinker with equipment. In particular, the tinkering drive is fed by wild claims for minor parts of the system such as cables. Objectivists, however, are often harshly dismissed by subjectivists as meter men—people who simply refuse to recognize what the subjectivists consider obvious. The debate is rather heated in certain quarters, and even the well-known skeptic James Randi chimed in on the issue [16].

[edit] Subjectivists' criticisms of objectivism in audio

  • Subjectivists will rely on demonstrations and comparisons, but believe there are problems in applying double-blind methods to comparisons of audio devices. They believe that a relaxing environment and sufficient time measured in days or weeks is necessary for the discriminating ear to do its work.[citation needed]
  • The introduction of switching apparatus, with either metal connection (mechanical switches) or electronic processing (solid-state switches), may obscure the differences between the two signal sources being tested.
  • In general, proponents of the latest technological solutions, such as the CDs at their introduction, use the technology's theoretical or ideal behavior, whereas subjectivists’ criticism centre on actual behavior. Subsequent introduction of newer, improved components often are marketed as lacking the problems existing with the prior generation of equipment, notwithstand this having been described as audibly perfect at the time. For instance:
    • audio filtering Subjectivists who defend analogue formats over digital ones point out that the process of reconverting a bit-stream to an analog waveform requires heavy filtering to remove spurious high-frequency information and such filtering would involve some signal degradation due to loss of information and potentially large amount of phase shift in the upper reaches of the passband. They point out that commonly-used consumer-grade digital-to-analog converters (DACs) exhibit very poor linearity at low levels. Both problems, at first dismissed, were then addressed by such solutions as digital filtering, oversampling, and the use of DACs operating at 20-bit (or higher) resolution. The introduction of the new higher-bandwidth high-resolution music formats is a tacit admission of the reality of this issue. Musician Neil Young, for example, is a harsh critic of the sound of the original CD format but has approved of the sound of the newer SACD format.
    • excessive feedback Subjectivists have long believed that sound quality is degraded by large levels of negative feedback in amplifiers. While this is untrue in the general case, poorly designed feedback systems can produce poor sound quality. Thus, the association of feedback with poor sound quality is likely a reflection of the availability of poorly designed power amplifiers that use feedback incorrectly.
    • capacitor types Subjectivists have long believed the improvement in sound they heard with higher-quality capacitors such as those made with tantalum. Sound quality improved when inferior large electrolytics or paper capacitors were replaced or bypassed with these improved capacitors in the signal path. Subjectivists believe that the capacitors were inferior due to significant inductance caused by their spiral-wound construction which interferes with the passage of the highest audio frequencies.
  • Experienced listeners can be relied upon for valid subjective advice on how equipment sounds. In any event, the eventual purchase decision will be made by the end-user, whose "perception is reality" and can be influenced by factors other than the equipment's actual performance.

Many subjectivists admit that, like with many other hobbies, their pastime contains a measure of cultish behavior. They may also admit that there is charlatanry among some vendors.

In Asia, hi-fi ownership and upgrading is often a hobby in its own right, where the pursuit of sound fidelity seems to be almost completely disassociated from the love of music. These "audiophiles" are solely into the gear. The music is just considered incidental or a means of "testing" equipment. The Chinese refer to this hobby as 發燒 or "fever outbreak."

The gulf between subjectivists and objectivists continues. Audio magazine, one of the few which combined lengthy listening reviews with lengthy technical analysis of laboratory measurements, has ceased publication. Stereophile and The Absolute Sound, however, each combining subjectivism with laboratory measurements, publish monthly.
