Just to tell you guys that I have just assembled Audio's Notes Dual 300B. Could manage to use the best components - Silver Wiring, Double C Core Interstage & Output TX, Jensen Caps, Jensen Four Pole caps, Vishay Zfoil resitors, the other resistors are all non-magnetic, Filament supply from Ten Labs etc. Sounding great with my Proac D-28 speakers. The amp is still in teh process of break-in. Usually the output TX takes 500 hours to break-in. I can briefly say that the sound is very open and cannot be compared with any solid state amp. Speakers can handle the load very nicely.
