Rear Channel fill

I have to start out by saying I was in high school, when the 4 channel or quad hi-fi made it's debut.  The discrete quad was very different, but appealing.  I remember in Nashville, on WKDA, they would broad cast the Quad hour.  That's not what it was called, but close.  Of course it was nothing like the quad LP's that were sold.  Real quad is mind bending.  Alas-no more.  Now, the debut of 5.1 surround, has let dad or husband get pretty good sound "for the family."
Sometimes, I enjoy adding rear channel speakers, at a low level, as "fill."  Some say they want to experience the live concert experience, but the only concert experiences I recall, that were of great quality, were classical concerts I had to attend for school.  In the right venue-wow.
I mostly listen to old classic rock, some hybrid bluegrass and progressive jazz.  About the only thing I can say about live rock concerts is that some of them, when mixed properly, are ass kicking, as far as sound that drives me into my chair-when sitting down,  Anyway, sometimes I like to add a little rear channel fill.  Am I alone?  I've had some say I'm not reproducing the "real' concert sound.
I dig it-occasionally.

I'm not wanting a real concert sound.  From my experience, I can produce better than concert sound.  In the last few months, I have had the privilege of seeing Roger Waters in two different states, David Gilmour in Chicago, which was the absolute best experience I've ever had, Mike Mcdonald, at the Ryman and several Eagles concerts that to me were primo.  I think I have the ability to better real concert sound, with one exception.  Gilmore in Chicago.  Best sound I've ever experienced.

It's amazing to me, how people can get off on tangents.  I'm talking about rear speaker fill, with the same source as the front speakers.  Da...

So you mean speakers behind the listening position making the same sound as the front speakers? Not anything I would want to do or hear, and imo not a desirable thing. But to each their own!

The digital time delay of yore was the best for rear channels, since the rear channels should produce only the ambient sound that is comprised mostly of reverberant decay. The rear channels were rolled off above 7 kHz as I recall. I had the six channel Audio Pulse Model Two time delay set up with all six channels. Whoa, Nellie!

My Denon AVR has Multi channel stereo mode, the front left channel signals are output to the surround and surround back signal left channels, the front right channel signals are output to the surround and surround back signal right channels, and the in-phase component of the left and right channels is output to the center channel, all channel level can be adjusted and unlike most DSP modes there is no delay built in, its fill up the room with sound nicely.
