"Balanced Output" Phono Pre-amp??

Balanced Audo Technology makes two units with balanced output and one that also has balanced inputs. Check out their site balanced.com I have their best unit the VK-P10 on our summer demo sale The ad is on audioweb

Aesthetix IO (as in moon, not ten) is balanced design and has provision for single ended output as plus or minus phase as well. Has well regulated outboard power supply, user adjustable load for phono cartridge, completely adjustable output gain for matching to your preamps inputs and the other components. And, one of the best sounding phono stages ever made. Tubes can alter the sound of this unit to be as soft or aggressive as you choose, depending on what you want.

Thinking of it, a cartridge is the only true balanced source in a stereo system. All phono pre-amps should be balanced, but there are hardly any.
