OL silver vs. Clearaudio Unify

The Clearaudio Unify specs show a 9 gram effective mass.
It is a unipivot.

The OL Silver specs show a 13.5 gram effective mass.
It is a gimbal-bearing arm with good quality bearings.

The Shelter 501 is a low compliance cartridge, with a 9cu compliance rating.

With the info posted above, I would say that when matching a tonearm to the Shelter 501 cartridge, the OL Silver tonearm has a better set of matching characteristics than the Clearaudio Unify.

Johnnantais, thanks for your comments. I expected that he knew the mass of the cartridge that he was planning to use. I certainly am aware of it, since I use that cartridge on an OL Silver tonearm, on a Teres turntable.

While I can understand your liking of unipivot tonearms, I would be careful about applying that to this particular set of choices in question. The cartridge in question is not a Decca.

Joel, yes you can do that, but it has its drawbacks too. Most methods like tonearm wraps will add mass, but will do it in both planes of motion. It is desireable to have lower mass in the vertical plane for good warp tracking, but desireable to have higher mass in the horizontal plane for better cartridge stability. The amount needed will vary, depending upon the other factors involved.

Additionally, the added mass may solve the mass/resonance need, but does nothing for the stability problem regarding unstabilized unipivots and low compliance cartridges.

John, nice response.
I have been around on these analog pages for awhile. You might have noticed some of my other posts. I actually have done some tonearm mods(called the HiFi) and made them available to the members, and have designed some turntables and tonearms that are destined for market in the future.
I do some analog design and other design work for a fairly well known audio company.
