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 top edges of 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.
PRICE INCLUDES four SHUNYATA POWER CABLES
May be able to deliver if that is cheaper than shipping.
