HT Preamp-Processors w/ Balanced inputs & outputs


I'm beginning to shop for a new HT Preamp/Processor to replace my Parasound AVC-1800 & I'm not finding many w/balanced inputs as well as balanced outputs.
If I'm using an unbalanced digital coax input to a pre-pro how is the signal modified to balanced output to the amp?...is there any type of signal loss/degradation?

I bought an older Krell HTS 5.1 not the Showcase. It has great sound and does most of what I need for movies. They can be had on Audiogon for $1500.00. They are balanced all around. I am running balanced to my Krell Showcase amp and unbalanced with the digital end. I am using a digital coax from a Denon DVD 9000 player.
my theta casablanca II processor is running with XLR or RCA. lots available on audiogon.
Arcam AVP700 comes to mind as does the Bryston SP2. The Arcam piece is a great bargain. I am a dealer for both if you are interested. Stay away from the Krell Showcase.
