I am hearing some hiss and thinking of getting new tubes. Not noticeable when music is playing but detectable from a meter or so from speakers when there is no music signal. None at all if preamp is off. The preamp will be ten years old this year and I am 2nd owner, FWIW.
The original tube complement is two 6DJB/6922 tubes and I bought a two JJ 6922 replacements from AVA a couple years ago.
Current AVA price is $50 for a pair.
I would appreciate any comments on options. While I think my ears are pretty good and I can sometimes hear the differences among different recordings (LP vs CD vs HDCD vs low cost streaming choices) I'm not going after the never-final edge of possible improvements with crazy prices. Paired with an AVA SS amp, I have been satisfied with the sound which favors some warmth, good sound stage, etc and is forgiving of less-than-perfect recordings. Not looking to become a tube roller.
Good sound and longevity and reasonable costs are my criteria. (Is it one of those things that you can have 2 but never 3?) If there's something out there at $100 a pair that would likely boost sound or longevity I'd give them a shot. Other ideas are welcome.
Thanks.
