Hi Kevin,
I've heard your Gershman speakers and they're surprisingly good with deep bass despite their smallish size. Congrats on having the luxury of a dedicated music room. Regarding your next upgrades, mind if I offer my $0.02 worth? I started with a similar Dedicated music room and found that the largest upgrade was the addition of acoustical treatments, not interconnects! You are likely listening to more indirect sound currently, and when combined with flutter echoes will substantially curtail the sonic dividends your carefully chosen equipment will provide. If you're interested in learning more, then check out Dr. Floyd Toole's book as a good starting place.
Cheers and keep us posted with your progress.
Kevin
