The amp and speakers you have are an excellent match. I think your problems lie elsewhere. Naim products are excellent on their own, but the upgraded power supplies really take the products to a new level. I would definitely try a HiCap on the Supernait before ditching this combo, as I think it's going to be difficult to achieve better sound without spending a lot more money. Get a HiCap - it really pulls everything together more than you might think. Also, what are your sources?
Amp Suggestions for Harbeth C7es3
I have a pair of C7 pairing with Supernait. In my current room (8'x10' room with speakers placed against 10' side wall), the combination is a bit too expansive. I would appreciate some opinions if I were to change the amp to get a little more high frequence air and better sound stage and sound image definitions. I mostly listen to Classical and Jazz music, occasionally vocal and pop, thus I don't mind losing a bit bottom end punch, as long as the bass definition doesn't suffer. I am also not ready yet to jump to the tube camp yet. Any suggestion would be appreciated.
