Gsoravil,
y.a.:
>>> What percentage of the overall gain from the stock 309 to the V with cable upgrade would you say was the cable itself? 30%, 50%?<<<
The vdH silver-hybrid is NOT the stock V cable, it is a separate "SME upgrade item" at least that is my understanding.
Only the V arm internal wiring is done with pure silver wire compared to the 309 high purity copper arm wire.
On the 309 I'd say the silver-hybrid phono cable was 10-15% max. improvement with the V definitely more noticeable about 20-25% maybe a bit more, if one would attempt to express this in a figure which is somewhat ~ questionable.
>>> Also, do you get the sense the damping trough would help the 309? <<<
No, I don't think the damping trough is value added with the 309 due to it's more benign high and low frequency behaviour. It starts to make sense with the IV.vi arm which is really not a IV arm, but a stripped down V arm.
>>> Lastly, if you don't mind would you expand on what type of table and cartridge you're running so I have a better idea of equipment class? <<<
As I mentioned, I use(d) a Windfeld (top of Ortofon's range, but also their Jubilee, the runner up).
The table is a SME-10.
Greetings,
