Modern High end vs. old receiver


So I recently sent in my Aesthetix Janus in for a capacitor upgrade, which leaves me without a pre-amp. In desperation for a little music, I brought in my the Kenwood Kr-3090 that I inherited from my grandmother and have been enjoying in the garage. 25W, made 1978-1981 or so. Damn thing sounds almost as good my Aesthetix Janus and Audio Research VT-100 MkII. Now don't get me wrong, there's a difference, but I can happily sit and listen and fully lose myself in the music.

I am using Acoustic Zen Adagio speakers, which work well with low-powered electronics, as evidenced by Robert Lee's matching them with Triode corporation tubes at the shows. I'm also using my standard front end - Oppo BDP-83 with Brystond BDA-1 and Acoustic Zen Absolute cables. Still.... jeez, it's unreal how much better it sounds than some of the other high-end gear I've had in here.

My learning from this is that the source matters, and you should not look askance at equipment just because it is old or inexpensive.

A point to keep in mind is that the better the quality of the source MATERIAL, the more apparent hardware differences will become, at least upon direct comparison. The inverse, of course, is also true.

Don't know how relevant that may be in this case, but it seems worth noting.

Frogman, I would hazard a guess that among nine out of ten non-audiophiles there would be consensus that the differences are slight. The basic circuit hasn't changed since it's inception. Serious differences only exist among speakers, the weakest link. You conceded to the law of diminishing returns,(which imo sets in by component, not individual person, btw) used the word 'little', and stated 5%. And then concluded the difference is more than slight.

Really?
Al, you're obviously blessed with better ears than me. Although I can hear quality differences with great recordings, it's the poor ones that seem to be a better yard stick for me.
