Dumb question HT bypass

Not sure if any AVRs have balanced pre-outs, but I use XLR cables from processor to preamp. Setup works just as Reuben describes. Source is either balanced stereo direct to preamp or HDMI to processor that sends balanced front LR to preamp.

Thanx Good explain.
Probably why I couldn’t get head around it, no pre outs on my AVR. 5.1 SQ now is quite enjoyable without extra cabling.
I knew that it was for sharing main speakers just not the logistics.
I actually asked for another brainstorm.
Thank ya.

Excellent explanation. I do the same and actually rarely use my 5.1 preamp at all because it just doesn't sound very good compared to the preamp I use for stereo listening. I don't know of an AVR that has XLR's, but maybe. There are multi-channel preamps that have XLR's.

The preferred method for HT bypass is to disconnect the AVR and leave it by the curb.

As I understand it, if you send HDMI to a processor or AVR that sends front LR to the by-pass input of a preamp, you're relying on the DAC in the processor, so it better be good.  I use a Bryston SP3, and its DAC appears to be very good.
