Analog outputs on Accuphase DP-75v

sorry Rich the experment isn't valid if using different cables

Consider Linkster's post: the player isn't internally balanced by design. In order to achieve a balanced output, they tack on a differential line driver circuit following the unbalanced output. Additional electronics are now involved in that interface - it theoretically shouldn't be any better - how could it possibly be?

Thank you all.

The Stereophile review eludes that the RCA and XLR outputs do sound different. The XLR being quieter, harmonically richer, with the highs being sweeter. The RCA is described as more color, faster.

I compared the RCA and XLR outputs yesterday by connecting both to my preamp and switching inputs. (I do understand that XLR invert polarity). I did hear more high frequency information via the RCA.

For my experiment, I had to use different cables. TARA The One on the XLR and Discovery Essence on the RCA. I am wondering if the difference I heard was due more to the outputs or to the cables.

I have an Accuphase DC-61 DAc and recently switched from RCA to XLR to go to my Pass Aleph P preamp. I noticed a difference... a bit more open and musical but a bit less resolution. Since it is not a slam dunk either way, I will need more experimentation, perhaps with different cables, before I settle on a choice.

RCA definitely sounds better in most applications (that is with a quality interconnect and reasonable length runs). Refer to Stereophile's original review of the DP-75V of several years ago. Given that your downstream components (either power amp or pre-amp) are not balanced will tend to magnify the degree of improvement by using the RCA (i.e. single-ended) outputs. None of Accuphase's single box players are internally balanced so this intuitively makes sense- in normal applications single-ended connections always sound better unless components are balanced designs and henced optimized for balanced connections (e.g. Rowland's Synergy preamp is balanced and doesn't even have single-ended inputs/outputs).
