What is the purpose of a balanced circuit. If you want it to reduce hum and noise you need a differential input. The signal does not have to be differential but both legs need to have the same output impedance to ground. The input must have the same impedance on each leg relative to ground but should be lower than the input impedance of the driven device.
question about Balanced signals.
I just purchased the Audio GD Vacuum HE1 MK3 which has true balanced design. I have an amp, Rotel 1080RB that is also true balanced.
my question is regarding sources? what if they only have SE output to the preamp SE inputs? will I at least get some benefit of balanced signal from the preamp?
@atmasphere Thinking of you :) just read "why balanced?" on your website. I need a pair of ICs since I traded in the integrated amp. would be nice to know that XLR for under $200 would be better than same budget for SE. Actually need two pair of balanced since my PS Audio Dac Jr has balanced outputs. Speakers are Martin Logan ESL-X with a SVS micro sub (system total 6- 8" bass drivers)
