Single ended vs. XLR Connection Advise Needed

Balanced connections theoretically will povide a tad more intertransient silence, but often you will discern no difference between the two, if your setup is low on noise anyway. I happily use both types in my system, but prefer XLRs for practical rather than sonic reasons. Your sense, that it will sound fine either way is probably right on the dot. Besides, as Craig rightly says: To each his own.
Cheers,

There is more sonic difference's between XLR vs RCA, take for example the single box CD/Players with Digitial or Analog Volume, The out-put on the single ended out of the units use (in most cases) 1 dac per channel where as the balanced outs (if they have it) use 2-6. In the case of preamps, most preamps have a higher voltage output with XLR vs RCA, witch in turn giveing you a higher gain at lower volumes. I have a balanced & single ended preamp that in balanced gives out 4x12db gain and in single mode only gives out 2X6db. I am a XLR guy, Its dead quiet and hassle free when I am doing any cable switching, those locking WBT's can be a pain in the A#$, if you know what I mean.

Caes in point. The Theta Miles ballanced version was far more better then the single ended, this had to do with the 2 dacs per channel out on the XLR path

True of course, but according to Hgeifman's post, that is not the point here IMHO.

In my experience, balanced IC's gain a progressive advantage over SE's as the length of run increases. This makes intuitive sense, since longer runs are more susceptable to RF interference, etc. At runs of 1-2m in a quality system, differences can be very subtle.
