    There is an outfit on the web called Headwize that has several class A headphone amp designs.

    Class A amps aren't too hard to fudge up. The power supply needs to be robust because the idle current is so high. My old SWT headphone amp puts out around .5 watt/channel & dissipates about 90 watts in heat.
