Writing just for future reference for others.
I steered away from all my initial plans and ended up with Class D monoblocks ! Yay! :D I know, some people are very against Class D sound, however in all AV shows, I was always attracted to Class D amps. My favorite so far being Kii Threes with integrated hypex amps.
I purchased 2 monoblock amps built with Hypex NCore NC500 modules. From a nice and super helpful gentleman named Tibor from Apollon Audio. These specifically:
http://www.apollonaudio.com/hypex-nc500-monoblock-amplifier-apollon-audio-nc800-slm/ I placed the order last week Wednesday, received the amps yesterday! They are looking super fine ! :D Couldn't try their sound yet, since I still don't have a preamp with XLR output. I will have Rotel RC-1590 for home demo this evening. I should be able to get some sound out of the amps :D
If they sound close to what people tell about these online, I will be a very happy listener! Another great advantage of these is that sound goes trough an opamp, which is interchangeable. I ordered it with 2 opamps already, will try both and return the ones I don't like. But later in future I can change opamps to change sound signature. Thinking of trying some Burson opamps in future.
After I try these for a while, I am thinking of ordering either one more monoblock or another stereo but use only 1 channel of it,, for driving center speaker from AVR. I am thinking of B&P IcePower 1200AS based amp, Apollon audio has these as well.
Currently trying to decide for Preamp, it will be either Rotel RC-1590 or Parasound P5 I think. I am also checking passive options, but I am leaning more towards active preamps currently, with ht bypass of course. If I will find the sound too analytical then I might think of a tube preamp to smooth things out. But I think I would be better off playing around with changing opamps on the amp.
Thank you all for your help !
