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.
Single ended vs. XLR Connection Advise Needed
What is the impact, if any, of using a single ended connection (RCA) from the CD Player to an integrated amplifier vs. a balanced connection from the CD Player to the amplifier via XLR cables? My integrated amp supports both connections (RCA & XLR) but I am considering a single ended CD Player (that is not balanced). My sense is it will sound fine either way but I am asking for some comments and recommendations. thanks..
