VPI Classic and ZYX 4D


Hi guys,

I am finally setting the TT and I was hoping to give it a shoot today but apparently problems never end.
I mounted the pick up on the tonenarm leveled the tonearm and I was just about to regulate the reading weight when I realized that even puching the counterweight all the way in I barely reach 1.2gr.
I own a ZYX 4D with the SB@ option which accordingly to the manufaturer it weights 7.9gr which should be perfectly ok.
I think the Dynavector Diamond is 7.5gr or something like that.
I have never seen anybody having this issues...I tried to reasearch but nothing.
I contacted my dealer but he has no clue.
I tried to call VPI but they are unfortunately close till the 13th!!!!
So I don't know what else to do.

If anybody can give me some help I would really appreciate.

Thank you so much.

Best,
Stefano.

What I wonder then, is where does the blame for such get placed? Is it then the sole fault of the Cartridge, the possibility of a mismatch of Arm Mass-Cartridge, or is it perhaps also a fault of the Arm design, being a Unipivot?

I know Myles previously mentioned the attributes of the use of a Damping Fluid being nothing more than a bandaid, and he is probably correct with this classification.

I know a number of times, Doug Deacon had made mention of not liking ZYX with Unipivot Arms, and I seem to recall the term used by him in his listening tests as "wooly".

Would/could this what Doug is perhaps getting at, because of the Unipivot Design, its lack of being able to be a compliment, and compatible to such a Cartridge?

It was the initial reason I suggested to perhaps try Damping the Arm slightly. Might be worth a try, and the results can always be easily reversed if not favorable. Mark
Hi Mark,

thanks for your post.
If have noted there is another user that had the same exact result but using a SME and Gra tonearms.
Neither one of them is unipivot.
So I guess it is not the toneare none is the matching since I have ran resonance (later and vertical) test and it is withing range.
The sound in outstanding, don't get me wrong.
I am just trying to understand if there is way to match the test tracks ot not.
I am starting to think that ZYX are designed not to track those tracks...I don't know it is something strange.
If the cartridge is extracting a Looott of details and information, why can't it track those test tracks that instead my old rega and denon did with much less retrivial information and detail and everything.

I will probably try damping fluid too.

Thank you for your tip.
Funny - your problems sound EXACTLY like mine with my UNIverse - I'm the guy who posted about the SME and Graham arms. I'm mostly using it in the SME V which of course is not a unipivot arm and my tracking results are exactly the same as yours - with distortion coming in the right channel no matter how high I track and how high I set the antiskating. I also hear occasional mistracking on normal records - more commonly towards the end of the side and most common with either dynamic piano or female vocals. On the other hand - I concur with you on the cartridges incredible ability to extract detail - I just wonder if there's anything I can do to improve tracking and extract even more distortion-free detail!

Please do keep us posted - especially if you find some sort of solution. Goodness knows I've tried EVERYTHING and basically just "given up" and put up with occasional mistracking...
right....I saw your post here and I was referring to you.

A question though:

I assume that sme has an antiskating system on the arm.
Do you have it down to zero or set?

I personally start thinking that ZYX are so particular that they are meant to be this way.
Nevertheless after I got the 12dB right and increased tracking force to 2.15gr I don't hear any mre noticeable mistracking..but all in all I have been listening to it for few hours.

I will definitely keep you guys postet on the eventual progress.

BTW speaking with Mike from VPI he told me that I should be able to get the 14dB and 16dB's one..but I don't know if he was being optimistic or what :)

I will find that out hopefully next week.
@Mark: I'm using the ZYX Omega-S Gold LO cartridge right now in a VPI JMW10.5i arm with no problems at all.

@Stefanoo: How many hours do you have on the cartridge? I've found with most new cartridges that they don't track real well until they have at least 50 hrs of playing under their stylus.
