I am hearing some hiss and thinking of getting new tubes. Not noticeable when music is playing but detectible 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 6922 replacements from AVA a couple years ago.
Current AVA price is $50 for a pair.
I would appreciate any comments on options. Note that while I think my ears are pretty good and I can sometimes hear the difference between 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.
Good sound and longevity and reasonable costs are my criteria.
Thanks.
Jay
