Hello Pgtaylor, the original idea of the team around Mr. Robertson-Aikman of SME turned against them.
Indeed - as Atmasphere already pointed out - it is resonance inside the magnesium armpipe. While all done and designed in the best intention,the shape of the magnesium armpipe with the widest diameter at the bearing does somehow amplify and ill-control armwand inherent resonance. The heavy pre-tension of the bearings doesn't ease things in this manner at all.
However - there is something you can do to lessen the effect and better the sonic performance of your SME V:
- do get "blue-tec" or something similar. Do apply small amounts (about the size of a cent) at the widest diameter of the armpipe and close to the headshell. It looks ugly, it will increase the effective moving mass, but it will dampen the unwanted inherent resonance quite well.
The sound will open up and will get more "air".
The SME V is a somehow fine example of a very impressive design approach with very consequent execution - cost little to o object indeed.
However - here two design features implemented with the very best of intentions combined to an unwanted side-effect.
Thank you - and Hiho as well - for your kind comments on my posts. Nice to get some positive feedback.
Cheers,
D.
