Well, that WAS informative. I really DO need a hearing aid ! A lot of those cart's were adapted/refurbished in some way, and I'm surprised that this 'survey' wasn't done with standard cart's. Of the 'variations upon a theme' cart's (Denon, e.g.), I didn't detect much difference, esp. in the bass and to be honest, they were all very similar at that frequency. Where the differences came was in the mid frequencies, with more delicate and delineated notes. Not sure why/how these coils had other makes of cantilever or tip as they're not user-replaceable.
I have to say, though, that whereas I thought the Denons were generally as good or better overall, it's the Linn Asaka that concludes the survey which I would choose. I did have a Karma in the eighties, though, so maybe my rose tinted hearing is biassed.
I have to admit that I listened on very old Senn, HD 450s without cushions. It should have been my cheap but modern Grados which my wife pinched. If I can find an adapter, I'll press my Elears or HD650s into service for a re-run.
Now how about a similar experiment with upper Koetsu, Lyra, Miyajima, Benz and Ortofon etc.? That would be music to my (failing) ears.
