Tonearm - Incognito VS Origin Live

Musical Surroundings shows a compliance figure of 15. That would make it a reasonable candidate for the HIFI Mod on a Silver, though right at the top of the suitable range of compliances.

Perhaps you could try a slightly lighter pair of weights than Twl used for his Denon and Shelter?

Leaving out the eternal bearing vs. unipivot arguement, why not go with Nottingham's arm? I here great things about it. If you don't like the wiring, you can change it out. And in theory it should have more synergy with the table...

Audio Note can provide a pure silver, or copper, wire kit for your Rega arm. An Audio Note service outlet could take your old arm and rewire it with audio note wire (thus turning the arm into an Audio Note ARM 1 or ARM2). The end result is a better sounding unit, once broken in, and a seamless run of wire from the cartridge clips to the RCA termination. No din plugs. The Incognito also uses a seamless wire run whereas the Origin Live does not is my understanding.

A seamless run is always preferable at least from a theoretical point of view.

The stock rega wire might sound better because it is not as revealing as the "better" wire. This would not be uncommon.
