Good MM cartridge - any ideas?

I have a Benz 0.4 and it does not put out enough to push the phono preamp.

Clearaudio Aurum Beta S....the more I listened the better I liked it. Sold it only because I had to have a Koetsu.

Shure V15VMR? Hums? Is there another problem?

I use a Clearaudio Virtuoso II in my TNT/JMW-12 rig. It's my current favorite over the Benz Ruby II, Grasshopper and Grado Reference. Transparency, speed, inner detail and timbral accuracy that you'd never expect from an $800 cartridge with 3.6 Mv output. I haven't heard the less expensive Clearaudio MMs, but I'd bet they're worth checking out, as well.

Ligi- I wasn't clear in my previous post- the series of cartridges that the LO.4 is in has a model that is at least 2 mV (I don't recall the exact output) which would easily drive your phono pre. Benz and other manufacturers make series of MC cartridges with two or three output choices. Assuming you liked MC and changing to MM just to get the output to match your phono pre, any thought of going with a high output MC?

Not trying to "sell" you on MC, but would hate to see you not get something you might prefer because you weren't aware it was available.
