Schiit Freya + is your best bet. I run it’s balanced outputs to the balanced inputs of my amp. Everything Else in the system is single ended and it converts them to fully balanced. Before running balanced I ran all single ended with hi-end cabling and the system sounds better fully balanced. Please note that my Freya+ took over 200 hours of burn-in before sounding its best.
Truly Balanced Cheaper Preamplifiers?
I recently came into possession of a truly balanced stereo amplifier. In order to get the best out of it, naturally I need to run fully balanced. New or used, tube or SS, preferably at the lower end of the $$$, can you give me examples of truly balanced preamplifiers?
