Shelter 501 versus Soundsmith Zephr ?

The 501 II does not work that well in my 9 sig in my opinion. Has a sometimes noticable upper mids peak and somewhat weak bottom end. Also has somewhat of a sibilance issue that can be moderated with a headshell weight from VPI.

I think it is not a good match for the 9 Sig. BTW, when you say JMW, you need to be specific. There are many variations.

Good Luck,
Robert

I had a 501 II in my VPI Classic with the standard JWM arm - it was ok, but unlike Robob above I actually found it to be too warm for my liking.

Haven't heard the Zephyr, but had another cart (Sumiko Blackbird) retipped by SoundSmith, and when it came back I was amazed by how good it sounded. I'm still using it (and have since sent the 501 II to them for retipping, though I've set it aside as a backup and haven't installed it since it came back).

Shelters are not good in VPI arms... Zephyr is much better for this application.

I just installed my Zephyr this evening on my Scout with std JMW9. I saw it here for sale last week, and thought I would give it spin out of curiosity.

Super easy to set up, no skating issues, and sounds BIG. Quite a bit more bass and detail than the 10 x 5 that has been installed for a few years. I have read on and on in these forums on how difficult it is to set up the Std JMW9. Either I am damn good, or just lucky. Half hour and enjoying.

my JMW is a 10.0 on an Aries 1 turntable. Just re-wired the tonearm with VPI's regular wire but my junction box got the nordhost valhally wire.

Now I am considering the SMMC1 which has a class A rating, and today just heard a Benz Glider S Low output which also sounded very good, but I have not yet heard any soundsmith cartridges although I started out way back with a Shure and have used Grado. I think moving iron sound must be somewhat different from low output moving coil sound, perhaps nuance versus image solidity and size??

It sounds so far from your responses like a soundsmith may be a better choice even though Shelter and Benz make great cartridges.

The effective mass of my JMW 10.0 according to Mike at VPI is 10.7 grams plus the weight of the screws so around 11 grams which is on the very low end of a medium mass tonearm.
