Ozzie,
The only light I can shed on the long term need to unplug Ground Controls, is that I do not need to. The catch here is that my system is not on 24/7. In fact, it is rarely on for more than 4 hours at a time, perhaps 3 times a week. So, my GC's are certainly discharging.
I will say that it takes a full CD before I have wall to wall floor to ceiling and 30 miles deep sound staging from the system. After that, the imaging and tonality remain stable for as long as I care to play music. But that CD worth of sound field expansion happens every time I turn the system on. I had been ascribing it to the tube power amp getting up to temperature and all of the electrical fields becoming stable, as that has always been the case with this Audio Prism Debut amp I have. Perhaps the GC's are also contributing and I just don't notice a difference. It has been a number of years since I mounted these GC's, so my memory for such trivia must be considered suspect indeed.
