ZYX Ultimate with carbon fiber cantilevers -- listener reviews?


Dear listeners,
Any "early adopters"/owners of the new ZYX cartridges that now use carbon fiber (instead of boron) for their cantilevers? If yes, would you please share your impressions and/or comparisons?
Thanks and happy listening,
Harvey

@unchilled  I've owned low output copper Premium 4D with silver base for some time, it was step-up from my silver coil Zyx Airy. On Live18 shell with dedicated pre-preamp (Zyx CPP-1) they were good on Technics EPA-100 tonearm. But after a few years of hardcore digging for vintage MM and MC i must say that Zyx was not my favorite cartridge, but it was the most expensive cartridge i have ever owned. So its not nescessary to pay more than $3500 for a cartridge if you're not sure it is "your sound". Not to mension all those vintage cartridges available 10 times cheaper in price, including vintage MMs to blow your mind.  

I still love Zyx pre-preamp CPP-1, haven't used for a while, but last night connected my 0.2mv Argent MC110 via Zyx CPP-1 pre-preamp to JLTi phono stage it was breathtakingly good.    
I have a r100 ultimate I'm going to try soon... will report in with my impressions in due course 

Mehran swears it bests the old Yatra and Fuji...  I won't be able to establish that but I'll consider it against my AT Art 9 and Koetsu Black...
@jjss49 i hope you know than R100 is an old model, lower that R1000 Airy 3 and way different from the Premium 4D. I doubt it can beat the ART-9, even my ART-2000 was as good or even better than more expensive R1000 Airy3. instead of the old ZYX you can also try vintage Monster Cable cartridges designed by Nakatsuka San. Even ADC-TRX MM was Nakatsuka San's design.     
@lewm you're right about UNI PRE cantilever - it's a kind of metal. I assume it's boron. But I do think you're a bit too cynical about the Zyx line as you put it. There is a substantive difference between the UNI II and the premium in my experience. I hear it pretty much the way Mr. Mak does in his review: the top end stays extended but the mid range thickens up (in a good way) and the bass goes deeper while remaining taught and detailed. It's not just repackaging to exploit the market imho. I bumped up to the premium when my UNI II broke and I didn't want to spend more money to stay in the same place. I didn't spend MSRP on the premium (and wouldn't) but I don't begrudge anyone who makes that choice. I mean, how is a $3k cartridge more 'logical' in the grand scheme of things than one that costs 3x more?
