I just received my UNIverse today - and since I didn't have my new phono preamp yet, I installed it on a friends Avid Acutus table for a quick listen. We did this during our lunch hour.
Before installing the UNIverse we listened to his Dynavector XV1s. My initial impression was that the Dynavector sounded great. In the first few minutes of listening, I mentioned to my friend that this was similar to the sound I was looking for. Upon continued listening, I'd say the Dynavector XV1s was somewhat slow, very precise and very refined. To some extent, the Dynavector XV1s and its highly refined character made me wonder if the cartridge would become somewhat boring to listen to over the long term. Instruments were scaled accurately but seemed somewhat recessed as if they were off in the distance - under developed harmonically & far less audible compared to vocals.
While we removed the Dynavector and mounted the ZYX UNIverse, we both commented about the "hi-fi" nature of the Shelter 901. The 901 being less refined somehow made listening more enjoyable - but the paradox is that the Shelter's splashy character always seemed to leave me craving more refinement.
Upon completing the installation of the UNIverse we listened.
What I can say to summarize my quick (15 minutes) with the UNIverse is that it clearly is a great cartridge - new right out of the box. It has similar refinement to the Dynavector but seems to have better developed harmonics which make it more interesting to listen to. Instruments and vocals seemed more balanced and equal. The pace of the UNIverse was to some extent on par with the Dynavector (somewhat slow). I wasn't expecting this because everything I've read about the ZYX cartridges proclaim it to be very fast - which was not my impression at all. Cartridges like the Shelter 901 or Benz LP seem to be much faster than either the XV1s or the UNI.
The UNIverse has a great precision again much like the Dynavector but couples that with an open transparency & sweeter more inviting highs that the Dynavector seems to lack altogether (in comparison).
My friend thought the UNIverse was "tubey" sounding - full bodied and somewhat rich in the mids. Again, this was different than what I expected - particularly having read much about the ZYX cartridges in general.
We both felt the UNIverse (not broken in) may to some extent exaggerate the size of instruments by a small fraction vs. the XV1s.
Well.. that's the best I can do in 15 minutes of listening to the new cartridge. I'll keep y'all posted as this thing breaks in.
So far I am very impressed.
