If this is similar to the preamp section of an NAD C-350, I thought it was not too good (imho, of course). Bright and grainy. If you can find a used Classe DR-4 or Four, or maybe tubes?, this would be better. I paid $550 for a slightly used Quicksilver LS and it sounds as good or better than the Classe and you don't have to leave it on all the time.
