I upped the ante and connected a Linum 2.5mm balanced cable to the JH-5s and connected to the balanced out of the AK 120ii - all I can say is...wow. If I heard this kind of sound before, I might not have purchased my Angies.
Then I connected to the balanced out of the CDM and another WOW. I think that's the best the JH-5s will ever sound...deep bass, good mids, and highs and a decent sound stage. For $400 plus the cable: a bargain in my book. It pushes it several notches closer to my Angies...which seems a bit overpriced now...
Back to the music...
