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)

Dear @dukebdevil :  I have  serious  doubts that your amplifier be a TRUE balanced design as you posted. Please read these:

 

" The voltage gain (into 8 ohms) was 28.4dB via the unbalanced RCA jack. This is slightly on the high side for a THX-certified design, but 6.7dB lower via the balanced XLR jack, which is very unusual. "

That was measures by in real time by STHP review ( J.Atkinson. ).

Additional to that in the manual operation Rotel stated:

" Rotel's balanced design. "

A true balanced design is only that a true balanced design but not Rotel's or Luxman's or whatever manufacturer name.

I think could be better that you forget about your OP with this amplifier.
