Best cartridge for JMW 12.5 tonearm?

Ceilalex,

Great phono stage. Since you have the gain and impedance flexibility to handle most LOMC's, it seems right to choose one of those, especially for jazz and classical.

Do you know your arm's effective mass? I can't find the specs on VPI's site.

The UNIverse is an outstanding cartridge, though Doug Deacon will tell you the copper wired UNIverse is better than the silver wire.

Almost. The copper is more to my taste and, perhaps, to the taste of most who've had the opportunity to compare them.

The copper provides cleaner, crisper more lifelike transients, particularly on leading edges. This gives the music a lifelike jump and pace.

The silver slightly burnishes leading edges, which imparts a more relaxed, less physically present tone.

Copper says Po-Tay-Toe, silver says pO-tAH-tOE. ;-)
