@cleeds @perazzi280 @atmasphere the pass xp-15 (and new 17) does not have a balanced input. My only source is a TT. I asked Pass Labs directly why no balanced in? FWIW, I received the following response:
”Probably because there are no phono cartridges with a center tap (6-wires) . So in terms of what we do with a balanced circuit you'd have to emulate that imaginary mid point.. At those signal levels it's always been a step backwards at the first gain stage. The super-symmetry circuit does that quite nicely but only at higher signal levels. Secondary is SE cables generally have lower reactance per foot than balanced cables.”
