What the heck is Resolution Audio

I can almost rationalize breaking my budget for $3000 by telling myself if I get CD55, I can eliminate pre-amp and go CD only......then it just as if I spent $1500 on each component, but end up with better sound. Really $3000 is a bargain for SOTA CD player, as many are $5-10,000+ range but unless you make six figures still a large investment, regards Sam

Does either the CD50 or CD55 have balanced (XLR) outputs? I need to run long interconnect, if I go directly to the amps. Will they drive 7m interconnect?

Yes, the CD 55 has balanced outputs. I don't know about driving 7 meters of cable.

They both have balanced and sinle ended outputs I have a CD55 in my office system I run one meter balanced out to my BAT power amp and 5 meter single ended out to my REL sub Works just fine They have almost double the out put voltage of most players with volume control It actually is a completely dedicated analog pre-amp built in for volume control

Buy it only if you want your ears pierced.
