User Experience: Sophia Electric Aqua 274B Rectifier Tubes

Hola Sue,

Yesterday I finally received the Aqua 274B tubes I ordered from you. They arrived safely due to the good packaging. Congratulations on that. They are really beautiful, but I think I would have preferred a clear/shiny glass envelope to match the rest of my tubes even though I understand the purpose for the lite blue tint.

Into my Artemis Labs DP-2 2a3’s they went and I couldn’t believe what I was hearing. I am not going to bore you with the usual audiophile jiber jargon. These tubes make Eva Cassidy, Rosanne Cash, Norah Jones, Alison Krauss, Willie Nelson, Supertramp, Pink Floyd, Roxy Music and Steely Dan (just last night) come alive through my Avantgarde Duos 2.2.  My wife had to force to turn the system off. Texture, tone, presence, soundstage, silence(lack of electronic noise) and body all were more readily presented without any discernible coloration. Bass is a tad tighter and dryer than my 1957 RCA’s 5u4g but I am sure that will improve with a few hours of break in. 

Great product and even better sounding that my GEC U52.

Keep up the good work. 

Best regards, 

Roberto, Puerto Rico
