Dynavector XV-1s What is the REAL story?

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.

For some reason on my last two carts I much preffered them at max. reccomended force when they were new and at much lower force when I had several (50-100) hours on them. Don't know if this means diddly, but yea, liking the same brand cart at two very different settings did happen, twice.
Also, I've read that some of the high end carts can have a tight sweet spot that varies with things like humidity. FWIW.

Dear Jeff: You are right. When a cartridge is new the suspension is to rigid and sometimes needs the max VTF but over the play hours the suspension is right on target and with less VTF sounds right.

Van denHul recomended this for my Colibri and really works.

Rigfht now I'm on that " game " with the XV-1 but I don't have yet any conclusion about on it.

Regards and enjoy the music.

most people use higher vtf to counter mistracing. remember putting the penny on the tonearm. I don't remeber what arm he was using with dynavector xv-1. Also HP tends to match what he thinks is the absolute best cartridge with the absolute best arm. Sometimes they are an ideal match sometimes not. Maybe he needs to experiment with other arms.

BTW,Raul--I knew,in advance of posing my question,that your response would be quite interesting,and in this case,seemingly plausable,as well.

Also,I'm not really surprised with the discrepencies displayed by some industry people,as you know.Alot of what we are exposed to is simply the marketing engine,at work!Do we really need more stuff?As regularly as we are told,we do?Do you really believe that there are "levels of improvement",that appear as regularly as the next issue of TAS,or Stereophile,with the "components of the moment"?Go to a dealer,or show event,and try to listen beyond the hype.If you've been at this for a long time,ask yourself if what you are hearing is really better than what you have assembled,over the time you have spent,in this hobby.Especially if you are an active hobbyist.You may be surprised,with the answer.

My point is that it is of paramount importance to trust your own intuitive senses!Not what we are told should be best!!Also,sure it's fun to get as technical,as we see in these forums,but in all truthfulness it is merely an exercise in technospeak!!ANY "newbee" out there,trust your own judgements,you will seldom make a gross enough error,that will dampen your enjoyment of musi Best!
