Rate my system/advise

I think you maybe consider set up and listen before go hog wild on more gear. A good rack is nice but you want real power in core where most needed. Wife sister have nice rack but maid have strongest core that my advice.

Hahaha I think i get it tubebuffer. Never thought of it that way but you seem to know what you’re talking about. I love a good core.  

Kinda lite on analog.

You do not need to spend the same amount on the gear as the speakers. Get some warm sounding gear for the B&W. My warmest sounding gear is the new KRELL XD line. Which likely would sound killer with the Audio Research and B&W.

I own the model 1 lower than this model linked below. I wanted to get the one on the link but the one I got was cheaper with less power, KRELL 175XD.

I have a NAD M22 V2 on the way to my house next week. When I demoed it a few years ago I found it a little warm, not the utmost in detail, but not bad. This is for some headphones.

$49 well spent to get a laser measure for set up.  Not just distance to front baffle from listening spot, also use it on sides of speakers to set toe-in and on top to set any tilt.  Way more significant than I'd have ever guessed until I fine tuned my position and geometry.  Its when you notice your speakers actually disappear.
