I have not heard the QuickSilver monos but at one time owned the CODA #8 and now own the CODA #16. For the price of the #8 I would get this instead.
Krell Duo 300 XD Like new Dealer Ad - US Audio Mart
I owned 2 of these Duo XD amps before and liked them more than the #8. They are smoother sounding than the #8. The amp that I linked above is 300 watts of iBias Class A. It sounds amazing. What that means is that the amp is not super-hot nor wasting a lot of electricity. It is not heavy either.
