Is mixing RCA and XLR cables bad?

To add to my concerns, just read this from Cable Solutions website:

“When considering the use of adapter cables, please keep in mind that while unbalanced to balanced conversion cables typically work well, the reverse is not true - balanced to unbalanced conversion almost always requires a converter device, such as the Jensen Transformers PC-2XR.”

This is exactly what I’m doing, ugh.  So I’m addition to my question about mixing XLR and RCA cables, am I still creating a problem just by using the XLR to RCA adaptors?

If your new Lyngdorf and your Mac both have balanced out and in why don't you just buy one lower cost balanced cable and use that. why try to make a balanced to RCA cable if you do not need it. Balanced cables are not as susceptible to noise induction so you do not need to spend huge money on balanced cables. 

Paul Mc Gowan from Ps audio has a topic about your sitiuation Jeff.My understanding is you are only getting half the benefit of what balance cable does if you use adapters.I am using  xlr to rca adapters as well made from Cardas.
