What's your budget? I use to own an AA Capitole Reference SE. I ran MIT Oracle V3.1's with great success. I have also used Stealth & Nordost will decent results.

For your information, AA plyers are not true balanced designs, the balanced output is derived from the single ended output through a device. I was told that by the designer himself at the Montréal Son & Image show a few years ago. So unless you run a long interconnect (that's what I do, as I use my AA Prestige as my preamp also) or that the component where it's plugged in has only balanced connextion, for ultimate fidelity, the RCA output should be the better one.
As far as cable goes, I use a 20 feet run of Van den Hul D-102. It's pretty neutral and is affordable for a long run.
Hope this helps.
