ty 89dB or more, 10 ~ 20W of pure class A amplifier can meet the requirements of the general appreciation. If we allow our ears in that environment dance hall in a large volume of long-term bear hearing will gradually diminish. Besides, fights neighbors no peace, but also inappropriate. So, if some of the power produced in better quality sound around 15W amplifier, static power at 100W or less, will certainly be a market. Unfortunately, this type of amplifier is a blank. Japan has a golden voice A20, Pure Class A amplifier for each channel 20W, sound reputation, but the prices are prohibitive. Now, the domestic production of power amplifier manufacturers seem to competition, power bigger and bigger, bigger and heavy weight, but sales did not necessarily good. Why not make some delicious not expensive, the amplifier to serve the market The spirit of this idea, we designed this 15W Pure Class A amplifier, trying to do something to try in this regard.
