et tu Koetsu?

Extremephono,once again thanks for your eloquent description.
Verybigamp, if you only use the Onyx 2 % of the time, what is your mainstay cartridge? Also, in your experience, is the Koetsu Onyx Platinum elevated in the high frequencies?
When you say yellow, do you mean lacking resolution?

Any Koetsu you want is possible when you are a close friend of the importer (NOT the distributer). Fortunately for me, that is the case here. Currently I am running a 'prototype' Urushi body with Rosewood Signature innards. Before this I had a Onyx Platinum Diamond Cantilever. Very nice cartridge, but my continuation of the ol' education comes first.

I got to see, touch, and hear the Tiger Eye Diamond Cantilever that HP currently has...SO BEAUTIFUL. Even so, I think my next Koetsu will be a Rosewood Signature Platinum Diamond Cantilever. That is, when I finish school, of course.

Forgot to mention, I've heard a UP that Extremephono desires. The one I heard was a very special cartridge made for the importer I mentioned. Incredible.

I upgraded to an ordinary Rosewood recently. Prior to that had been using an original HO Glider and the Clearaudio Wood Sigma. I like the Sigma, but the Koetsu is miles ahead in musicality and smoothness. I use the Koetsu straight into a cj PV9A and a Mac C29. It is wonderful, period.
