Quite simply this is far and away the best "small format" amp I have ever used. I've had the Lepai, Topping, HLLY, Virtue, and several TPA3116 based amps.
Rated at 25 watts/channel and can easily drive any reasonably efficient speaker with ease.
Condition is a solid 9/10. It's fit/finish/build is definitely in a different class compared to the Chinese Tripath based amps.
It will give 10x the price a run for their money. This is way overkill for any computer system that you may have.
It is labeled as a Monoblock on the front, but it is a stereo amp.
This amp sells for $320 USD + shipping from the UK and even at that price is a steal.
I am asking the modest sum of $150 SHIPPED. Comes with a very high quality power supply.
