What is the purpose of the 12AT7 in Atma-sphere MP3 line stage only version? Does it have any impact on the sound? Does the brand matter? or is it just important that it be low noise?
I'd check with Ralph first. He's one of the truly good guys of audio and a real straight shooter. Hope you enjoy your MP3 -- I had one for a number of years and found it immensely musical and fleible. -- Bill
