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.
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.
