So you have a great hi end stereo preamp, but

Why can’t the OP use a HT processor that has analog pass through so the analog signal bypasses it’s DAC, straight to the amps?

Oh, he can. For sure. Probably does. So what? Its still ruining the sound merely having the thing in the same room. People probably think I’m kidding, or exaggerating. I am not. I tried all this stuff, and with much better processors than any avr! HT is a wasteland. Guaranteed to bring down any system, any price, even just being in the room and turned on. Not even necessary to connect it to anything. Its that bad.

The great writer Harlan Ellison, speaking of Joan Collins, said, "Her mind is a vast barren plain, across which winds play, endlessly." That’s HT.

I have my AVR surround system in one room and my hi end stereo system in another.  The sound that comes from the hi end system has  depth, air and 3 dimensionality, and the texture of the music.  The AVR system thumps,and punches in a solid 2 dimensions, even though its a surround system.  There is no delicacy.  Some of my friends prefer the AVR system.....

I figured it out.  OP is really Dory from Finding Nemo.  Ugh.

The problem was discussed on different forums before and most common conclusion is to have two separate systems.
