I have this amplifier with RCA 6V6GT tubes and all other tubes are RCA too. A Marantz UD9004 superaudio CD and a couple of Altec Lansing A7-500 speakers are the rest of the system. The sound the A300 provides with this system is outstandingly HIFI. Sound is clear and refined without over-sweetness or gross distorsion. Vocals and jazz and solo violin and cello are at their best here: Diana Krall, Stacey Kent, Jose Feliciano...

I bought my A300 on CL a few years and recently had it restored by a friend of mine. I will never, ever sell this amp. It is my opinion of sonic perfection.
