Is a Koetsu Rosewood Sig Overkill for my JMW 9Sig?


My system has evolved wonderfully over the recent past.
I'm running a few year old ZYX Airy Vintage on a Scoutmaster with center & ring weights via a Cardas Neutral reference into an EAR 864 full function preamp.
My Cary V12 drives Wilson Audio Sophia I's.
Will the 9 Sig (With 3 gm headshell weight) allow the Koetsu to perform its' magic? Is is a worthwile upgrade?
My musical tastes range from vocals to classic rock to chamber music to symphonic extravaganzas.
I'm not at all unhappy with the ZYX (just the opposite). Just looking for another flavor of magic. I'll probably keep it as well.

Thanks for your explaination Bill.
FWIW, I would say that overall I agree with you.

However, I do not regret the year I spent with a ZYX UNIverse on a JMW 10.5 arm. I would say that the it was immediately obvious how good the ZYX was upon installation on the 10.5.
I will also say that I am hearing even more now with it mounted on my Vector 3 arm.
So IMHO, the VPI arms are good enough to hear the differences between top shelf cartridges, and I would not be ashamed to put any cartridge on one.
However, there are other arms out there that are capable of better showcasing what a top shelf cartridge is truely capable of.

If Harry from VPI can recommend a dyna XV-1 on his scoutmaster, I am sure the Koetsu will do just fine and sound great.

Let me know how the Koetsu sounds, as i just may buy one for my HRX

cheers
Audiofeil -

Do you feel that VPI's 10 inch arms (10.5i) are in the same category of arms as the 9 series? ie. not optimized for top shelf cartridges with lower compliances like the Shelter, zyx, xv1s etc?

Do you feel the same way about all unipivots?
Goat,
I sent you a private email but to capsulize:

I like the 10.5 better than the 9. Is it the best match for the UNIverse and/or XV-1? No, but better than the 9.

I have nothing against unipivots. Actually I sell a line of unipivots.

Look, I've posted my opinions based on my experiences. If you find them similiar to your own, fine. That's great. If you don't and disagree, that's fine, too.

I don't care.
Does anyone have experience replacing the Scoutmaster's JMW 9 tonearm with something better?
What did you choose?
