There were also a few modifications of the V15 Type V-MR – the Ultra VST-V, and Shure’s best-ever cartridge, the Ultra 500, which had a tip mass of 0.165mg, and the best trackability of any Shure cartridge. Both had a recommended tracking force slightly higher (1.2g, versus 1g) than the V15 Type V, and hence better trackability due to the higher tracking force. However, the Ultra 500 cost significantly more than the V15 Type V-MR – around 35% more in the USA, according to the 1987 Audio magazine Annual Equipment Directory. The styli were interchangeable between the V15 Type V, Ultra VST-V and Ultra 500.
There were also several models between the V15 Types IV and V, the ML140HE, and its upgraded ‘brother’, the Ultra 400. The ML140HE had a laminated core like the V15 type III, IV and V, but with fewer laminations, which I suppose saved money when manufacturing them, and a nude hyperelliptical stylus on a beryllium tube cantilever. The Ultra 400 was the same, but had a microridge stylus tip – the equivalent moving tip mass was 0.19mg (V15 Type IV 0.29mg, Type V 0.17mg, V15xMR 0.17mg), so it was better in trackability than the Type IV, but not as good as the Type V or V15VxMR.
Thanks for the info on the Type III. Thought that it was simply an aluminum tube. Now I have even more respect for Robert Kita, the designer.
Yes, that was confirmed some years ago by occasional AK member Les Watts, designer of the ML140HE, which he designed to Shure’s brief of a ‘half-price V15 (Type V)’, that the Type III had a beryllium ‘stub’ on the cantilever.The ML140HE was for a time second only to the V15 Type V in the Shure line.
Would you please provide, if possible, a "pecking order"?
Here’s my estimated list of Shure cartridge rankings, best first, rankings based on tip moving mass and trackability, magnetic core type and stylus shape:
- Ultra 500 (V15 Type V-MR modified for lower moving tip mass of 0.165mg)
- V15 Type V-MR, Ultra VST-V (as per Type V, MR tip)
- V15 Type V (HE tip, beryllium tube cantilever, tip mass 0.17mg)
- V15 Type V-G (as per Type V, conical tip)
- V15VxMR (similar trackability, beryllium tube cantilever and MR tip shape to V15 Type V-MR, but non-laminated core, so eddy currents in the core will mean a less-flat high frequency response, tip mass 0.17mg)
- Ultra 400 (ML140HE body with MR tip, laminated core, beryllium tube cantilever, tip mass 0.19mg)
- ML140HE (laminated core, beryllium tube cantilever, HE tip)
- VST-III, V15 Pro/S, Realistic V15-RS (same body as V15VxMR, HE tip, beryllium tube stylus)
- V15 Type IV-MR (the MR tip was a later upgrade for the Type IV stylus)
- V15 Type IV (laminated core, telescopic aluminium tube cantilever with beryllium stub, HE tip, tip mass 0.29mg)
- V15 Type IV-G (as per Type IV except with conical tip)
- Ultra 300 (same body as Ultra 400, ML140HE and ML120HE, telescopic aluminium tube cantilever, MR tip, tip mass 0.3mg)
- ML120HE (laminated core, telescopic aluminium tube cantilever, HE tip)
- V15 Type III-MR (as per Type III, but later upgraded with MR tip stylus)
- V15 Type III-HE (as per Type III, but later upgraded with HE tip stylus)
- V15 Type III (laminated core, aluminium tube cantilever with beryllium stub, elliptical tip, tip mass 0.33mg)
- V15 Type III-G (as per Type III, but with conical stylus)
All of the above cartridges, except for the Type III models, have Shure’s Dynamic Stabiliser brush, which damps tonearm/cartridge resonance, short circuits record static electricity to ground, and removes dust from ahead of the stylus.
Would you please provide, if possible, a "pecking order"?
Or is the suffix number, a progresive indication of sound quality?
Yes, effectively higher type numbers (in the V15 series) are better than lower numbers, because of improved cantilevers, lower moving mass (and hence better trackability), and (usually) better stylus shapes. But Shure usually had a conical stylus shape version of later model V15's, for those who preferred a conical stylus.
I've heard (and owned) some, but not all, of those listed.
