Preamp choices:Short list

Nearly all components have massive transformers mounted way over on one side in order to keep them away from sensitive circuits. Because of this its very hard to find anything that is truly balanced. A simpler solution is to just move the springs around to where it sits level.

Can I ask why you want balanced interconnects/gear? 

I had a Rogue RP 5 and it is the single ended version of your preamp., plus a phono stage.  I found it to be very good sounding.

@russ69 , I currently have a 20 ft RCA and get noise. I'd like to get to a fully balanced system. My DAC and mu phonostage are balanced as well

This is an incredible BALANCED preamp (read the TAS review from 3 weeks ago). It will not alter your signal with "enhancements" that a lot of people like. Sounds like your DAC, phono, and speakers (and maybe wires) can add the tone and leave the preamp with no signal enhancements.

I owned the BAT 42VK-SE it is not as good as the 1/3 the price LA4 or HPA4 refereed in the links above. BTW - Vicktor at BAT will always service those units or maybe the guys that bought BAT.
