I am sure this has been asked before, but not in the last year anyway afaik.

I'm aware of the theoretical benefits of balanced connection to a power amp vs. unbalanced. Right now I have a G91 and a G57 - connected unbalanced of course - and I am looking at getting a G68. I had been looking for a G68AXV or G68XXV on the principle that long runs to rear speakers would be better served over balanced interconnects with the power amp for the rears located near the rear speakers.

But I have an opportunity to get a used G68J at a good price - i.e. no balanced. So in real world practice - how much difference would I really gain from balanced?

One other consideration - at some point in the future I may move to a Classe CA-3200 for the front 3 speakers and use the G57 for the rears. Speakers are currently B&W Nautilus 804 (used with G57) with a (someday when the stock market recovers) plan of acquiring B&W 802D and HTM2D or HTM1D for the fronts and moving the current pair of N804 to become the rears.

many thanks for any advice
