Home Amp/Preamp Asylum

Looking for a new Amp or Preamp? If you're after tubes, post over here.

You missed a few good criterion.

You want minimal crossover distortion in class B amps, class AB amps show worse crossover distortion which can be audible.

Sure higher bias sounds better, and you may not leave class A operation depeding on your listening habits, but.............

IME and IMO, there is no comparision between class A and class AB or B, Class A amps do sound superior.

You also want a high PSRR overall as well as for each individual stage. This can make or break an amp's performance often making power supply quality less of an issue.

You want good open loop performance, meaning gain and frequency response. Feedback should be used as/if/when needed and should not be shunned, IMO.

I would chose lateral mosfets as output devices. In my limited desgin/building expereience they do sound superior to BJTs, all things not being equal.


Never attribute to malice that which can be adequately explained by stupidity.
