Cartridge-- M/M or M/C

First I will state that I am no expert here. I, too, have MMF-7 and after researching this question myself I came to the conclusion that the Pro-ject 9 arm will not mate well with most, if any, MCs that are low compliance carts. If that is the case it does cut down on the field of choice for cartridges. But I think there are alot of decent cartridges left that will mate well with the Pro-ject arm. FWIW, I'm running a Shure V15vxmr and am happy with it, but I am curious what other cartridges are available to use on our MMF-7s that would significantly improve the performance.

Well I am not sure if this info will help but, here is my present system. Rogue M-120 Magnum monoblocs, Rogue Magnum 99 preamp, Rogue Stealth phono stage, Music Hall MMF-7 TT and Proac Studio 250 speakers. And of course last but not least from the digital end, California Audio Labs CL-15 CD player. All with Discovery Cable interconnects and Signal Cable Power cords.And Apature silver speaker cables.
Now with that said, I have never been very fond of the Stealth phono stage. Right from the beginning it sounded thin and bright. And that is what I still have. The stealth is pretty flexible in it's terms of selection of set up parrameters. It has opened up some in the last 9 months of operation but, it is still not to my liking.
But to be honest, I was never sure if it was the Rogue or the Goldring Eroica H cartridge. I would like to darken it just a bit.
Does that help at all?
Thanks guys, Scott

A shorter answer this time: Dan has probably hit the nail on the head. Your cartridge is not suited to your 'table, and your 'table is totally outclassed by the rest of your equipment. And given a chance, the Proacs will sound bright. If you keep your 'table, then the Shure - my personal favorite in the "play music and forget about audio" field - will flesh things out considerably. Being an excellent all-rounder with perhaps the best bass of any cartridge, it will also improve in sound when you get a 'table to match the rest of your system, at which point you can start to consider more exotic and risky cartridges. You can enjoy a larger record collection and get an idea of what your Stealth can really do.

What table combination would you recommend for my system in the $1000 used market?

The proacs sound wonderfull with the CD player. That is what is killing me. I know that the TT should sound better than it does.
