Okay, I have had the GC spades on my DeVore Super 8's for about a week now and I am getting the same results as Ozzy. A very nice improvement in sound stage width and front to back layering with a more relaxed and palpable presentation.
Like Ozzy, I too have the SR Power Cell SE, Apex ic's, and Tesla pc's. However, I have found that the SR Power Cell, as good as it is, would increase the sound stage at the expense of added glare. So, I now use an Audience PDC for my integrated amps. This gave me a wonderful sound stage that is relaxed with perfect pitch and the GC spades have taken this to the next level.
Ozzy, have you tried the standard GC rca's yet? I am also curious if you are running your amp into the PowerCell.
