Integrated amp: Component weight

I'm an older guy with a bad back looking to spend $5-10K on an integrated amp.  Before I get into functionality, connectivity, or even sound quality, my threshold considerations are price, power, and weight.  My 86dB-sensitivity Harbeths do best with the equivalent of a 200-300wpc solid-state unit, I need to drive a variety of analog & digital sources, hope to keep weight under 40lbs, and want to stay away from "classic" Class D designs.  Been there, done that, D simply didn't work in my system.

My question: Does anybody know of any published listing of amplifiers that compares products by weight or size?

So far, I've only found a few 15-35lb models that meet this initial filter, from sellers like Ayre, Devialet, & Bryston, and, surprisingly, even ARC.  However, there are connectivity & functionality issues that make these otherwise-terrific options a poor fit.

Any suggestions?
