ZYX Omega or UNIverse?

I'm used to finicky. The Replicant stylus on the A90 is something of a spoiled cat, demanding and imperious but worth the effort to win over. As a general rule, where have you settled for VTF and VTA (relative to level) for your UNIverses?

I am using a VAC Sig 2 Preamp with an IO Signature phono with dual power supplies. The Universe sounds fantastic with this combo. I run it at 47K and weight about 1.95 grams.

VTF
This varies by sample so my exact number or anyone else's is irrelevant. I've had UNIverses happiest at 2.00g, others happiest at 1.40g and everywhere in between. In addition, every sample changes its optimal VTF frequently due to aging, weather conditions and even the LP you're playing.

You must learn to adjust VTF by ear, certainly every day, sometimes for every LP. If you don't do this you aren't listening attentively or hearing all the cartridge can do.

I've posted my VTF methodology many times. Very briefly:
a) find the mistracking point
b) play .01-.03g above that
The window of optimal VTF is no more than .01g wide. Listen and learn how to find it. Too light and bass suffers/highs go fuzzy (just before actual mistracking occurs). Too heavy and highs suffer/microdynamics are muffled/slowed.

VTA (more correctly, SRA)
The ZYX stylus is similar to the A90's in terms of finickiness. In general I found the A90 a bit easier to tune, even though I was less familiar with it.

For a starting point, just level the ridge near the bottom of the ZYX body by eyeballing vs. the record surface. Don't spend more than 30 seconds doing this, since it's only a place to start. Fine tune by listening.

Gotcha. Thanks.

How do you compare the universe to the ortofon?
