Home Theater Bypass , why am I hearing this now.

Bottom line: 3 pieces needed

AV Receiver - all surround speakers hooked up as normal, main front L and R come from main pre out

HTBP pre amp - HTBP main L and R in from AV receiver pre out

Power amp to main L and R

Result 1 = 7.2, 9.2, 11.2 or whatever you have for movies works as it should, total movie theater equivelent as to sound

Result 2 = 2 channel streaming to L and R mains, perfect stereo listening

No compromise at all to each. PERFECT integration of theater and 2 channel stereo listening through the same set of main L, R tower speakers. Love it!

 Yes. This is what I have done.
With an integrated amplifier , a Processor , Power amplifiers.
No compromises , perfect integration. But it is expensive.

Sure it is.... at a minimum, you have to purchase the whip snappy AV Receiver 2K, 3k maybe. Then you get to purchase an expensive pre amp and an expensive power amp. BUT..... when you are done........ ooooh, so nice. Switch from Movie surround mode to pristine 2 channel stereo mode with the push of one button on the remote (htbp on; htbp off)...... so slick and perfect.

Wow when I first step seeing some of these responses I was lasting to myself this is what others talk about when they lol audiophiles snobs. Glad to see there are others feel the same as me. I know my setup is good but not as good many on this board. But I believe I did a good job of setting up my 2 channel and then taking care of Home Theater.  Who ever said what is the difference in having a pre with HTBP than just a pre is right.  There really isn’t. Make that sound the best you can do/afford and then add rest.  

The important point is it’s more than doable and there are a lot of options depending on budget.  

I’ve had an a separate amp / pre with HT bypass in the chain with my HT receiver.  I’ve swapped Front speakers, streamers / Streamers around.  I’ve had a class D amplification in my HT receiver and paired it with a much more powerful class A/B amp that costs multiple times the receiver which was not a cheap receiver.  
Today I have an integrated Tube Amp - Primaluna Evo400 (2 Channel w/Hat Bypass) paired with an Anthem MRX-1140.  It pairs well for movies, no issues at all with integration of the Tube amp into my HT set up.  2 channel is the flip of a switch and I’m in 2 channel tube heaven.  
In every set up I have tried and combo the 3 constants I have had are no issues with the integration of the pieces - HT receivers auto calibration tools can work wonders on that front, that the separate amplification / pre for 2 channel always has sounded quite a bit better than the HT Receiver for 2 channel and adding a separate amp to the mix improved the surround sound of the receiver, opened up more power for the other channels.  Key that the HT receiver is totally out of the 2 channel chain, I’ve tried it as a Pre to separate amps and doesn’t deliver the same 2 channel performance, even with direct analogue pass through - unsure why.  
I 100 % agree with Big Greg on how awesome a Movie experience can be with a HT set up.  I watched John Wick 3 last night in Dolby Atmos and it was an experience.  You can’t get that without the HT set up, period.  I felt shot gun blast, felt like I was in the rain storm and that I needed to wipe off the broken glass that had sprayed in my direction.  And then I flipped a switch and enjoyed a little 2 channel listening before calling it an evening. 
What you can argue is that if I took all the money I have into the 2 channel gear over the years or vice versa, the HT gear, if I applied all those funds to one or the other I would have an even better set up for whichever I picked, as long as I selected the right gear.  I love HT and 2 Channel listening and I have 1 space for both and I still am quite happy with the results for both.
