Shadorne, good catch... Yeah I would bet fact is the richness and harmonic resonance of vinyl is in fact part of the whole equation.. However I have been lucky as of recent to find the miracle of room acoustics, I just treated my whole room with Killer results! Digital sounds nearly just as smooth, not all recordings hit rock bottom, but more of the panels I add keeps getting the room deeper and deeper in the gut region. Now of course you can overdue it, and I am done adding panels, very excellent balance, However I will probably get some of the little foam corner wedges to run along the long part of the ceiling soon cutting off that one major 90 degree angle left over.
As for balance, My Digital and Analog sources come SUPER close now, some albums show very rich bass, but the Cd's that are done low compete very well now too. Also for a good solid dose of analog bass in a digital system, I can't recommend Highly enough of giving a Cardas Digital cable a shot, this is the most analog I have heard CD since getting a hold of one for the Coax digital duties.
