I am extremely satisfied with this set up, finally. I believe I've hit the point of diminishing returns untill I get to about double the retail of this.
I'm kinda in the same boat as you. Trying to increase the 2ch performance in a HT setup. No, a TV in the middle does not help anything out.
-Does you pre/pro have analog pass thru? This might help. -Install dedicated power lines. This was by far the most cost effective improvement I ever did. Tons of threads here about them, keep things simple. Basically run a wire from point A to point B. Sounds more difficult than it really is, but even for professional installation the cost/performance is get, in my case. -Vinyl....I'm still strongly thinking about this. I heard really good vinyl and it was great. Whole different topic here, but if you want great 2ch performance......
In reality for a truly deep sound stage I think you need really, really big speakers. Something I heard once. I have the ML Heron-I's across the front and they really only scratch the surface in my opinion.
I think if you made any major change, start with the pre/pro as this can really affect the soundstage. Amps seems to really make more bass in a generic sum up.
