Hi All,
does the world need yet another tonearm, I ask?
Me, - I'm not so sure actually.
But here a few point I took note of:
We were getting our knickers in a twist over dynamic vs. static arm balance (all know by now what this is, yes?).
Along comes the innocent-man talking about a uni-pivot arm. Most of all, that ALL the best arms are uni-pivots - ha, hallo!
And nobody even raised a flag?!
Since we all have listened by now to the apparent 'must have' of dynamic balance ---- show me a uni-pivot with dynamic VTF!
THAT, is a contradiction in terms, and so the best arms (uni-pivot) are now fine sans dynamic balancing??
In fact, even a knife-bearing = pivoted (but not gimbled, like a compass) can NOT use dynamic balancing. The spring action will want to lift the arm off the bearing(s), and make it rattle.
As to the most talked about and therefore = best arms by deduction = uni-pivot --- Anti Skate is almost as problematic too.
The Skating force is not equal from begining to the end of a record, so any Anti-Skate is yet again a sort of compromise. With a uni-pivot it has the tendency to tilt the arm i.e. affect best chosen azimuth.
So then we can carry on by adding magnet stabilizers like AudioCraft and Graham, or add more pivot points like a 4Point Kuzma, but dynamic balancing --- no go!
So are we saying these arms "the most talked about" are also sub-optimal?
I really don't know, but it would suggest some designers are truly busy wasting their time with faulty design principals.
To be complete, all those 'string suspended' arms would of course also fall into the 'sub-optimal', as NO dynamic balance can/aught to be applied there also.
Funny thing is, those arms were all tested and found to sound really very good --- now what?
