Thanks for your opinions. I think I'll look for a CJ.
Although I have heard that the ARC stuff can be harsh when listening for extended periods, I suppose I was just dreaming that they softened up with a "REFERENCE" preamp.
That's alright Bill, we can all dream. ;^)

Most people giving you advice aren't really knowledgeable about what they are saying.
Well I guess we could have asked your question number 1, cable length. However, many of us non-knowledgeable buffoons know how to perform a basic Google search and find out that his amp, the Classe CA-2200, has an input impedance of 100K ohms, which shouldn't be an issue with any preamp, and answer your question number 2.
Actually, the question that probably should have been asked, which is more important than either of your two questions, is: Are you looking for more resolution or more musicality?
IF he really NEEDS to run balanced, which is highly unlikely, I would recommend BAT over ARC, UNLESS, he is looking for detail, detail and more detail.
Some folks do like ultra high resolution. I've seen folks pair Thiels, ARC and Nordost cables. It's enough to make most folks ears bleed, but in the end, you pays your money, you makes your choices.
FWIW, I've owned CJ and ARC preamps, as well as VAC, Cary, BAT and a slew of SS preamps.
Cheers,
John
