If I were in your shoes, I'd look at: Ayre EX-8 (24 pounds), Aavik I-180 or I-280 (20 pounds), Hegel H390 (40 pounds), or CODA CSiB....but that is definitely pushing it at 50 pounds.
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?
