MM cartridges


I recently picked up a used Merrill table and having an audiomods arm installed. I am interested in installing a MM cartridge only. My choices are Grado reference, Soundsmith Aida, or Decca London super gold. Has anyone tried these cartridges and can offer feedback?

Right Pryso, Kuzma arms come standard with continuous wiring from cartridge clips-to-Eichmann Copper Bullet RCA plugs (THE way to do it, IMO), with a choice of copper or silver (at extra cost). Robert Levi has his London Reference on a copper wired Helius Omega, feeling silver wire will be too brash with the London. My phono and line stages are both tube (as is my power amp), so either will probably be fine, silver providing a little more resolution and low-level detail. Powder1, the Audiomods arm is also available with copper or silver---which does yours have?
As I said, I sold my Kuzma arm and table. Mine came with Straight Wire - copper wire with black braided wrap. Looked like this only without the DIN plug, it was continuous..

I bought mine years ago and don't remember being offered a choice with the wire.
The choice of wire may be a recent development. It's not mentioned anywhere on the Kuzma site, I only learned of it when speaking with Scot Markwell. Silver wire increases the price of the arm quite a bit, more than seems justifiable. There's nothing "wrong" with copper wire, after all! But I'm glad arm makers are starting to do the internal wiring in one continuous piece, from cartridge clips to RCA plugs. It's standard on all Kuzma arms, and an option with both Audiomods and Helius.
