Hooked the amp up to my RTA12C's & I'm very impressed! Just couldn't imagine that an iPod could sound this good! Stunning! No, of course not as good as a cdp, but waaaaaaay better than I expected. For non critical listening, it's killer!
I'm also running my NAD cdp through the amp & it sounds really good too. On my next day off I'm going to do a comparison w/the tube amp and my NAD integrated. Will post findings.
