Meridian 508.24: Balanced vs Single-ended outputs?

I run my Meridian 508.24 into a Jeff Rowland Concentra integrated amp with the XLR Harmonic Technologies Pro Silway II cable (1 meter). From my viewpoint, there is less noise and the background is quit. I suggest you borrow an XLR cable and see how it sounds. This is the only accurate way for you to make a decision. At the HE 2003, Harmonic Technologies Pro announced a new Silway III cable. cheers...

I run my 508.24 into a Krell KCT with a 1 meter XLR Harmonic Technologies Pro Silway 2 cable. I previously used a Synergistic Alpha Sterling RCA IC but this sounds better. Now the "noise floor" is simply not there. Total quiet background.

I have used both RCA and XLR on my system with my 508.24. Generally, the RCA will not be as loud (about -3dB quiter). If you are not running huge lengths of interconnect between your CD player and your preamp, RCA is fine. Besides there is a certain symmetry with having one's system be all RCA or all XLR.

RCA shall work good at your system.
