Horrible amplifier. Tons of high order harmonic distortion + load dependence of frequency response = worst possible amplifier features.
Sir, you're
not living in the past enough
By the standards of 1980's popular priced 'enthusiast' amps which are now classics, this thing performs really well and better than the emerging high end valve 'confections' fetching a small fortune on the used classic market.
You know, there are a few oldies like me who honestly believe we haven't moved forward in amp design since the 70's, but have gone cheap and backwards... I'm frankly stunned how a little board like this can function as an amp at all, let alone with reasonable of low power and feel sad for those audiophiles stuck in the past who don't realise how much more capable solid state devices (output transistors for example) became as the 90's wore on - all these old behemoths with a dozen or more output transistors a channel for example...
This thing is not terrible and it's VERY cheap! Fine for a simple small desktop system, the speakers hopefully not having a difficult loading.
