"@westcoastaudiophile ...tube amp changes sound every hour.. listeners age as well! LOL"
Ya know it's a really good point on both fronts. I have been listening to my tube amps at 2hrs vs 6hrs over the past 4+ years, and question myself sometimes if its the changes in the tube amps for different reasons, or my hearing changing more as I get older in the same day listening session. Strangely enough, listening on a late Sunday night after a nice long weekend, can sound amazing for whatever reasons, less static in the air -or- less static in the brain after some nice relaxation and rest. I just hope I can maintain hearing long enough to still enjoy it. Cheers :)
