You said and purchasing, ripping, and selling CDs . I hope you didn't mean that you condone the practice of buying a CD, ripping it then selling it on whilst keeping the rip?

I think this discussion about ripping a CD and what you can or cannot do with is so over.

The test data for this amp look like something out of the deep dark hacker past! I got a little Topping for use with the computer (and some mid-sized old Altec bookshelf speakers) that sounds wonderful including clear, tight bass. For less than $100. Main complaint is lack of power - OK for the computer, but I wouldn't want to try driving anything much bigger or in a bigger room.

looking at the board design this amp was clearly designed by linear amp designer

"If you see toroids in the output filter, shudder. If it's mounted upright, shudder once more." Bruno Putzeys

Its like they read this article on what not to do and then do That.

Everything from transistor positions, ground board design, connector positions, filter components it is Bad i dont think this amp will pass CE FCC.
