Jafox,
I do not think so. The recent degradation of sound due to quality of electricity is more observable on the better systems then on the dull. The fact that his CD still sounds OK says only about an unfortunate quality of that Accuphase player it even with the good power lines sounds not particularly interesting.
BTW, to your information only during the last week I intentionally auditioned 12 totally deferent systems the sound of which I know very well and ALL of them demonstrated the VERY SAME sonic signature that never was there before. (Also I have a conformations from MANY other listeners). Besides
the problem might and has already been corrected by using the clean power lines
So, I might propose that my diagnoses was correct, or at least VERY plausible.
John, I understand that you have fan to BS about the application of the habitual audiophileic wisdom but unfortunately to sing the songs about the changes of the tubes, apply shielding and end of the life of your funny Koetsu will not work in this case. Fortunately for you, kids, there was an idiot who already went over all imaginary troubles after the sound suddenly died two weeks ago. The idiot knew what he was doing, and went through everything lately (!) event totally rebuilt his phonostage! This idiot was Romy the Cat and he shares it with your guy just in order you do not panic and do not rapid my stupid actions.
I have a number of VERY serious and very credible people who experienced the VERY same result at the SAME TIME in their context of serious and very capable installations. So, I am not kidding, and sincerely proposed that in Carls case it was the electricity. Besides it is very simple to verify. Are any bids accepted?
Good luck,
Romy the Cat
Sitting next to the dead system.
