Dynavector XV-1s What is the REAL story?


I have read the performance parameters required for best sound in this cartridge, by the great HP,which I found interesting and perplexing.I then read,what seems to be a complete about face of HP's findings,by Mr Fremer,in Stereophile.Mr. Fremer does make a valid argument(we're talking tracking force)for correct alignment in the coils,and claims the mfgr's suggested force is the way to go.Makes sense,to me, NOT to stray from what the original designer has recommended!Yet,what do I know?It also seemed that MR Fremer was intentionally making the point,that HP was a bit clueless regarding downforce.

Well,now we have the "new audio pioneer"(I do like the guy,alot)Arthur Salvatore,on his "really fun to follow" web pages,stating that after much experience,with the XV-1s,he has concluded that MR Pearson was RIGHT,in recommending a downforce considerably higher than even the mfgr states.Obviously Mr Fremer would be incorrect.Even though his argument follows the line of ultimate reliability,as well as performance.All in a product costing about 4500 bucks--????

So,my argument is this---"WHAT THE HELL IS GOING ON"???

We have a very expensive product that has gotten a considerable amount of press,where the supposedly top reviewers in the industry cannot seem to agree on a parameter that will DEFINITELY affect both sonic performance,as well as long term reliability!

They claim that "Newbees" are in short supply,and the industry is shrinking.Hmm,I wonder why!

Do we ALL cancel our subscriptions,to these "once hobbyist oriented" journels?Do we rely on forums like this to garnish the "TRUTH",where there STILL are those who "jump" at the opportunity to tout their Favorite possessions,and put in a good word for their favorite designer/manufacturers?

Or do we start to rely on our own sense of perceptions,which(believe me)really begin to "sharpen up",after you have spent your hard earned cash!!

Any thoughts are always welcome!!

Dear Sirspeedy: This is what I answer ( off-line ) to the same VTF question of one Audiogoner:

+++++ " I try my XV-1 with damping and with out it and at the end I choose with out it. My XV-1 is on my Micro Seiki RX 5000 and I use a self design phonopreamp ( phono/line in one unit that I love it ), I think that I don't need the damping. I can " see " that you have an excellent TT too: the Acutus ( I like it ).

Now, about the 2.6 gr. On the VTF my opinion is: the manufacturer range is between 1.8 to 2.2 gr. Why all cartridges manufacturers give us that VTF range? : it is because inside that VTF range the cartridge coils are centered and this is a critical point in the cartridge performance.
You choose a VTF out of that range, so the coils are centered-off and the cartridge sound reproduction change. If you like it or not is another issue:
the point here is that your XV-1 is running out of specs. You like more the " colorations " of an off-centered coils, that's ok.
In the long run that " heavy " VTF will do a degradation on the cartridge suspension that could affect in a severe way the future sound reproduction of your cartridge and can ruin your LPs. Take care about and ask directly to Dynavector, maybe they approved it. " +++++

That same day I ask directly to Dynavector in Japan and the Dynavector Technical Director give me this answer:

Before these question/answer I run my Xv-1 at 2.2 grs. with very good performance, after the Dynavector answer I try 2.5 grs and finish in 2.4 grs: great performance.

Now, Mr. Fremer is right on his statements about and I agree with him, at least on this subject.

The opinion of Mr. Pearson ( that I respect ) is totally out of take in count : he speaks of 2.6-2.7 grs, he is totally wrong and he can give that kind of opinion because he maybe don't pay 4.5K for that cartridge and he don't care about his LPs damage. Now, Mr. Pearson has a high frequency problem with its ears, he not only does not care about the VTF manufacturer recomendation, he don't care about load impedance either: he always run any cartridge at 47K, obviously he needs equalization.

From Mr. Salvatore ( that I admire for his constant support to his web site ) he is wrong too.

+++++ " Or do we start to rely on our own sense of perceptions " +++++

Here we can't do that: these kind of cartridges are really expensive and our beloved LPs deserves that we take care about.

Regards and enjoy the music.
Raul.
I track my XV-1 (no 's' FWIW) at 2.2g. I heard absolutely no improvement musically or sonically at higher VTF settings. If anything, I thought the cartridge's high frequency performance was slightly compromised at VTF settings that ran much beyond the manufacturer's recommended 2.2g upper limit.

More importantly, I found that the music's pacing began to suffer at higher VTF settings, which is a serious drawback in my book. Swapping the XV-1's excellent rhythmic drive for a doubtful improvement in sound effects is a lousy trade if you care about musical involvement.

Based on their writing and/or equipment choices, it seems that HP, HW, and Salvatore (and Fremer too, for that matter) are basically clueless, or at best indifferent, when it comes to reproducing music with its timing and drive intact.

I spoke with Mike Pranka (the US distributor for Dynavector) about this, and he said the manufacturer cautions that 2.5 grams VTF is the upper limit that the XV-1 should safely be able to handle. I think it's reasonable to assume that exceeding that limit would cause premature wear or damage, skew the SRA, and certainly throw the moving coil out of alignment with the magnetic gap's sweet spot.
Why the assumption that there is a single correct VTF? It's been my recent experience that VTF does effect multiple aspects of sound quality. It's possible that given their respective systems and listening preferences that two perfectly competent people could arrive at different setup settings. I must admit that the difference is quite large in this particular case.
I have owned the XV-1 for 6 years now well before the so-called reviewers started glamourising the cartridge. I have tried it at the so-called HP 2.6 - 2.8 gms and in my system with my normal ears it just sounded different. HP is full of crap stating that it does not track correctly unless you track it at 2.6gm's. I also load my XV-1 at 47k thru my Pass Xono.

The cartridge tracks just fine and sounds just fine at 2 or 2.2gms. I think dynavector knows a bit more about cartridges, especially its own than HP. Fremer is correct, follow the manufacturers specs.

BTW, I think Raul got confirmation from dyna that you can safely use the XV-1 at 2.4gms without any potential increase in wear and tear on the cartridge.

cheers
