Which MM cartridge?

I own both the Ortofon 2m black and the Clearaudio Virtuoso Wood. Both are Stereophile Class B. Well, for my taste (classical and some jazz) I prefer the Ortofon.
It's sound more vividly, fast and clear. I don't know if the output is the reason, the Ortofon is 5.5 mv and the Clearaudio is 3.5 mm. For me, the Clearaudio Virtuoso Wood (as all cartridge from Clearaudio) are overpriced.
Ortofon 2m black price is $669 and the Clearaudio Virtuoso Wood is $875.
Good Hunting.

On a previous turntable (Rega P3 with RB300) I went from a Dynavector 10x4Mk2 to a Clearaudio Virtuoso Wood to a Dynavector 20xH. My order of preference was 20xH>10x4Mk2>Virtuoso. Of course these things are subjective but I found something about the Virtuoso un-natural sounding and ultimately disappointing, especially for the price. The less expensive Dynavector cartridges were far superior in my opinion. In fact, I'd say that the 20xH is among the finest cartridges I've heard for less than $1500. IMO a "special" product that performs well above what its price range...

As an owner of an MP-50, I will second the Nagoaka suggestion. I haven't actually heard the 500, but it is speculated to be the same cartridge as the 50.

Mine is sounding great on a Well Tempered Reference feeding a Ray Sammuels Audio Nighthawk.

I recently picked up a used Grado Reference Sonata 1 and I like it better than any other MM cart I've heard, including the Ortofon 2Ms. Great value if you can find a good one used.

Clearaudio Maestro is very worthy.
