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)

All of those criteria are met in a proper balanced circuit.

mashif is correct. You would need the first balanced device to have a transformer at its input so as to convert the SE input to balanced.  It would then pass a balanced signal to the downstream balanced device.  But most often, the inputs on balanced devices that can also handle an SE input will simply amplify the SE input; the negative phase is internally grounded for SE and the positive phase (of the balanced circuit) carries the signal.
