Shelter 501 questions/concerns


Ok, I've read all the archives from Twl and others, but I'm curious if there is anyone who is actually using a unipivot with the 501, or has heard such a setup. I got a good price on one from a dealer and I just pulled the trigger. My arm (Bluenote Borromeo) is a unipivot, so I guess I am taking a chance. But it does appear that a few JMW owners are having some success.

BTW, the Borromeo has an off-center additional weight behind the counterweight to aid in tracking duties. I think I will be ok, but would like some feedback from anyone with a personal experience to share.

Thanks,

I only voice concerns based upon trying to give conservative advise. I have heard of the Nottingham Space Arm, WB arms, and Graham 2.2 giving what the owners called good results with the 501. It is possible that your arm may work well also. I'm not sure.

My concerns, as stated in the past, regard not whether it will play in the arm, but how close to optimum it will be. This is something that you will have to decide for yourself. If you feel that it works well, please pass the information on to us, so that we can have some good user info to work with on future questions.

My general advise is to buy a tonearm with the cartridges that you plan to use, in mind. Then you don't get caught in a position where you already have Tonearm X, and then hope that it matches with Cartridge Y.

If the 501 works well for you in that arm, you are in for a treat, because the 501 is a really nice cartridge.
I had a 501 (known then as the "Crown Jewel," distributed by Sounds of Silence several years ago when I bought it) mounted on a Graham 1.5 t/c (medium mass) unipivot on a VPI HW19III. I had no problems with it, and it sounded pretty good. I don't know if I was able to get the nth degree of performance as TWL describes. Both Fremer and Pearson reviewed the Crown Jewel favorably in the magazines. I don't remember their setups, but I think it's likely that at least one of them used a unipivot during his review. I don't remember any negative comments. Good luck.
As I have previously posted (more times than anyone else likely wants to hear) the 501 sounds GREAT with my 'Not Spacearm uni. That said, Tom Fletcher has incorporated stabilizer bars within the arm pivot so as to improve lateral stability on that arm. I did have occasion to hear the 501 just this weekend with an OL Silver arm (without Twl mods!) mounted on my Spacedeck and really could NOT tell any appreciable difference between it and the Spacearm on that table. The OL Illustrious, yes - big difference; the Silver, no.

I am totally unfamiliar with your arm, so what I relate may be meaningless to you.
