Surprising. The Umami blue is a relatively warm catridge. I agree with suggestions to have set up checked by a professional. Or may be deffective. 80 Ohms is borderline. Of course it dépends of the set up but 100 ohms is recommended. Is the gain to high?
Personaly, I had a Hana SL and upgraded to a Pure Fidelity stratos at 2000$ A bit less detailed, but more Bass punch and sound stage. The reviews on the Stratos are simply outstanding and so is my listening experience.
