Koetsu Blue Lace Onyx vs. Coralstone

No complaints. To each is own, and glad you're enjoying the A90. I would think Koetsu owners may be curious what you use for a phono stage, and what TT/arm you used. That said, all that matters is you are happy w/ your Ortofon.

Fjn04 - Phono stage is Whest Ref V, arms I've used the carts with include Origin Live Conqueror, SME V, Ortofon 309-d (12"). TT is a Consonance LP5.0 Mk2.

I have not tried the SME 5 w/ my Jade, but it seems to be the arm recommended most w/ the heavier stone body Platinum's.
I don't know the Whest, but is recognized as a top tier phono stage. Certainly it seems as if you gave the Koetsu a fair shot, but simply prefer the Ortofon. Enjoy.

Dear Sprog, What tonearm? No surprise that you like the A90 better than your Koetsu. Apparently many others would prefer it as well. Koetsu is not my religion, but I hope you will pardon me if I say I still enjoy my Urushi and will continue to do so. (Never heard a stone-bodied Koetsu.)

I certainly would not be among those who would trash you or the A90. In fact, I own and enjoy several different cartridges and have had some thoughts about acquiring an A90 myself. But I heard an A90 in direct comparison to the new Allnic Puritas cartridge, both on the same turntable and in the same brand of tonearm. (Two arms mounted on the same tt.) I have to say that the A90 was very fine, but the Puritas was a shade less mechanical, more "musical". I hate when folks use that word as a descriptor of audio gear, but there it is.

Sprog, Sorry for my redundant question. I see now that you listed your tonearms ahead of my request that you do so. I have inadvertently learned lately that the Urushi does its best in what one would call "high mass" tonearms, i.e., 20 gm, minimum, FWIW.
