cd player with xlr outputs

Here's my take. XLR or balanced connections include a third wire so there is a hot(+), negative(-), and ground. In addition, there is typically some type of signal booster or mini-amplifier at the XLR output stage that boosts the low-level signal from the standard 2volts (via RCA or single-ended connections) and doubling it to 4 volts.

This 2 volt boost and 3 wire configuration is intended to sustain the signal for much greater distances before signal degradation occurs.

The potential negatives of XLR connections is that these little signal boosters or mini-signal amplifiers can inject new or raise existing signal distortion levels and thus degrade listening pleasure. With better equipment, this typically is not an issue.

The potential benefits include allowing for greater cable distances and usually a small boost in macro-dynamics and bass punch.

XLR is only as good as your amp. Is your amp truly balanced? I was a bit amazed to find that using my balanced Audio Aero CD player on the balanced (XLR) inputs on my McIntosh Amp made no differance as the amp is not truly balanced.

My experience with XLR connections is the exact opposite of the above post and I too do not have a truly balanced amp. I'll admit that on other amps, the XLR difference was obvious but mininal.

I find that, with exactly the same cable brand and model number, the XLR always sounds slightly better. My guess is that the things the cable introduces is just cancelled out.
