Absolutely IMHO/E, one`s mind set/mood can and does have a decided effect on perceived SQ, especially, the onset of the depression, when one`s system sounds like crap, where, a day or two, etc. before, it sounded so wonderful !!
And yes, it was some what much easier, and better, when we knew less, and had less, or no exposure to better playback systems owned by other`s..
And even when we appreciated better, sadly our pocket books often couldn`t accommodate our sonic desire`s/fantasy`s !!
But, some of us had goals in that direction, and pursued it..
While you maybe laughing/crying, I sometimes find myself looking back and shaking my head on my expenditures, effort, and that`s why I stopped chasing the last .01%, I`m just happy all my systems function properly, sound good to my ears(the guy who pays the bills) and I don`t have to screw with it, or pull some errant gear and fix it, because I didn`t purchase reasonably HQ equipment, or in some cases re-store/rebuild it properly, so I can simply use and enjoy what it`s supposed to do : reproduce music in a pleasing/satisfying manner..
Take care Chris, and thank you for the kind words, and best holiday well wishes, and I re-submit the same return, in kind, as well..
Kind regards, Billy Ferris
