Well, I have finally balanced it...


I replaced my single ended cables with the same make/model of balanced interconnects, Tara Decade and Tara Air-2, between my DAC and preamp, and between my preamp and amp.
-Amp - Accuphase P-450
-Preamp - Pass Labs Aleph P, Gain at 12 o'clock
-DAC - Accuphase DC-61
-Transport - Sony 9000ES
-Speakers - Proac Response 3.8

These are my findings:
-The gain increased by 3dB to 6dB.
-Bass was much fuller and stronger.
-Mids were more natural and smooth.
-Highs had a bit more resolution.
-The sound was a bit quieter, more musical than technical.
It was not, however, as large a difference as I expected. When I do my next cable upgrade, I will likely stay with the balanced setup, probably using Tara The One, which is out of my budget range at the moment. (I know, I know... I need a turntable and tubes!)

Blueswan, your thread is very timely as I have just decided to try the same thing. My amp and CDP are both using truly balanced circuits so I will be trying some XLR cables in January. I will keep you posted to compare results.
Hi Blue
Still running that P450 eh? Glad I found one for my own - wonderful amp to go with my C275. The thing is, neither of these, nor anything else that I'm presently using is truly balanced end-to-end, so although I've wondered about trying the same thing that you've done I can't help but wonder if it's the right way to go? I know - just try it - there's just no other way to find out what'll happen. But the balanced interfaces are "tacked on" requiring the signal to pass through *additional circuitry* which I don't believe could possibly help matters. Maybe I'm wrong though - want to trade cable sets for a couple weeks? :) I've just upgraded to Synergistic's X-series Designers Reference with MCC-III, and I'm certainly wowed! Well anyway, thanks much for sharing your experiences!
Hey Bob
After several days of listening to my balanced cables, I have noticed more air, or separation, between individual instruments and vocals across the soundstage left to right as well as front to back. I did not have this to this degree with single ended. I feel the upgrade to balanced was worth it. How do you like your C-275? I would eventually like to get an Accuphase preamp but my Pass Aleph P with its adjustable gain is going to be difficult to part with.
