Lon,
I'm following up on the discussion of buying new input tubes every year after 1500-2000 hours of use (30-40 per week) That's the premise.
I use 6922 type tubes that are rated up to 10,000 hours. I recognize the tube is degrading throughout its usable life. Have you tested your one year old tubes? If so, how did they test compared to new? Which tubes have you used and how did those tubes hold up?
I ask these questions to further my understanding of tube life and utility.
If anyone else wants to contribute to this discussion, please do.
If Steve would add his understanding to this, would be greatly appreciated.
I might add that stating one tube is better than another is frought with fragility. All ears aren't created equally. Shape, acuity, and environment are always different. Stereo components are also unequal. No two components are identical in construction. Micro differences in wire length and thickness. Etc, etc, etc. Therefore, any given tube type and brand will be affected. I might have a high frequency hearing deficiency, which has me liking tubes that particularly emphasize such. Just to be clear, hearing deficiencies occur in multiple ways. It isn't just high, mid or low frequency deficits. People suffer different effects from any specific type of hearing loss.
My point to this discourse is that some, including Steve and his being "uniquely able" to make the claim cryotone are the best tubes, will claim a best tube, but it's only best to them. Lon, Will and myself each like different tubes in their respective amps. Each of us have had the Torii. We do not have the same cables, speakers, front end, software (streamed signal, cd, vinyl), rooms, room treatments or lack thereof, so on and so forth. Steve has an opinion and he has probably acknowledged it is just his opinion, when it comes to what sounds best.
Enough said.
Peace
