I have a dedicated music room in our basement. It has been extensively treated acoustically with bass traps and diffusors in all the right places. This is the best listening room I've ever had. I listen 90+% of the time to classical music. This system does a great job of reproducing acoustic instruments. Violin, cello and piano timbres are rendered very realistically. System dynamics are outstanding. Recently added the Starkrimson class D monoblocks which are undergoing extensive listening trials.
You approach to 2-channel with surround intrigues me as I have never given this any serious consideration. I have a 2-channel preamp with HT pass through and an HT pre/pro.
Having probably done some research into this before you proceeded, can you tell me if I am on the right track?
Send signal from my 2-channel preamp additional output to my pre/pro as another general analog input. Program my pre/pro to treat this component/selection to play with only rear or surround speakers and find and set a delay (my prepro sets delay based on distance from the listening position - so I could play around with that distance based on either what it actually is or change the distance to a result that I like the sound of).
I will need to check if my pre/pro allows me to designate the number of speakers and which speakers by input. Since my surround speakers and my center channel speakers use the same 3 channel amp.
This won't give me just the out of phase information, but will send the whole ball of wax to my pre/pro, then you recommend just playing around with surround programs to figure out what works best?
