Jdub39,
I had the same question on the same amp I own - Halo A21. The Parasound brochure does indicate using a XLR input for the best possible sound. But when I asked this same question to Parasound they mentioned that it did not matter. A search on the internet also mentions that use of XLR input on this amp takes it to an altogether new level. I will be interested in experimenting with the XLR inputs when I get my system out of hibernation.
