	Stereophile: Bel Canto PL-1A universal disc player
		Bel Canto describes the PL-1A as including "a combination of innovative analog output stage and D/A conversion design, low-jitter internal slaved-clock DVD drive operation, a superb power supply and careful parts selection.
		Whether the signal was sent to the Revel Studio or B&W N802D loudspeakers, the sound was neither laid-back nor forward, but "there": wide across the front, deeply extended from the speaker plane back, and with a transparency that let the music and musicians engage and startle, as they can in concert.
		But with relatively neutral equipment and room acoustics, the Bel Canto PL-1A almost disappeared as an influence on the sound and was equally transparent with all formats.

		A bel (symbol B) is a unit of measure of ratios of power levels, i.e., relative power levels.
		The number of bels for a given ratio of power levels is calculated by taking the logarithm, to the base 10, of the ratio.
		Therefore, one bel corresponds to a ratio of 10:1.

		The d is therefore lowercase, as it is the SI prefix deci-, and the B is capitalized, as it is an abbreviation of a name-derived unit, the bel, named for (United States inventor (born in Scotland) of the telephone (1847-1922)) Alexander Graham Bell.
		In acoustics, the decibel as a logarithmic measure of ratios fits well to the logarithmic dependence of perceived (The magnitude of sound (usually in a specified direction)) loudness on sound intensity.
		The decibel unit is often used in acoustics to quantify (The sudden occurrence of an audible event) sound levels relative to some 0 dB reference.

	Acoustics (Site not responding. Last check: 2007-10-19)
		Acoustics commonly refers to acoustical engineering, and is the study of how sound behaves.
		The sound pressures we study in acoustics are measured in decibels (dB).
		When speaking of acoustics, one must be sure to differentiate between sound pressure levels[?] and sound power levels[?].

	General concepts
		Bel is the logarithm of the ratio of two power values.
		Hence the Bel unit is considerably large, one tenth of it is used (the same concept as discussed above for more frequency resolution), and the resulting unit is called decibel or (dB).
		Noise reduction coefficient NRC is the arithmetic average of the sound absorption coefficients at 250, 500, 1000, and 2000 Hz, then this average is rounded to the multiples of 0.05.

		When a speaker (or anything else that has the ability to vibrate) moves forward, the air molecules in front of the cone are compressed, causing the molecules to run into each other moving them all forward.
		A Bel is the difference in loudness produced by a ten fold increase in power.
		The ear drum acts as an âacoustic suspensionâ system, using the air trapped in the middle ear to control its movement.

	SN Letters to Editor
		The “bel” is really just a method of notation that signals when data is being presented as a logarithm of a ratio.
		To use the “bel” in a meaningful way, the reference value must be stated because the “bel” is used in several engineering disciplines.
		For example, in acoustics, sound pressure is presented using a reference of 20 mPa (an SI unit) and sound power is presented using a reference of 10-12 W (also an SI unit).

		The d is therefore lowercase, as it is the SI prefix deci-, and the B is capitalized, as it is an abbreviation of a name-derived unit, the bel, named for Alexander Graham Bell.

		Each of these masters of 19th century opera is represented by two scenes on a disc made in the splendid acoustics of the Masonic Temple of New York with the Orchestra of St Luke's, conducted by Patrick Summers, Music Director of the Houston Grand Opera.
		In fact, the early part of Fleming's career was dominated by bel canto opera, long before she became famous and admired for the music of Mozart and Strauss.
		As she says: "I feel that bel canto is the very definition of everything that is great singing in that it requires the greatest accomplishment of all of the vocal repertoire.

		But to put things back into perspective, the DAC2 is a LOT more affordable and a lot more realistic of a purchase for most of us, yet it goes a surprisingly long way towards approaching the PLayer's performance.
		Now if unreasonable expectations resulting from a much more expensive Bel Canto source component experience are unfair, than unreasonable expectations resulting from Bel Canto's Evo4 amplifier are downright wrong.
		The DAC2 gives you a good taste of the Bel Canto house sound for barely over a grand: strong dynamics and bass, natural but not overwhelming detail, and a sense of palpability through the midrange.
