Looking for a CD Player w/XLR Outputs...

lots of adapters and cables with mixed ends exist

I used a set of xlr/rca adapters for a while, I did not hear any deterioration

....also, if you have a CD player already, just without XLR, consider keeping that and buying a DAC with XLR out $600.  There is the Denafrips Ares II which can be had for $550 $600 on USAM or other sites today.

If it's not too old for you, the Sony SCD-1 had XLR outs.

I would be extremely cautious with amazon adapters. Unless you don’t value your equipment 

If you already have a dac get audiolab or Cambridge cd transport.
