Very rare Champagne finish. These have just been upgraded to the new top  3.3 and have all new tubes. There are dings to the face plate I have taken close up  pictures of.   Very open, clean, and effortless sound with zero grain or mechanical character.  After hearing these, it flaunts how other amps can have a strong character.  System matching is of course still the main factor for any audio equipment to jump from good to WOW.
