I really appreciate all of these comments. I had a conversation with Soundmith, but I'm still researching this issue. Since I have a Shelter 501 stereo cartridge (which the mono cartridge will be going up against), I'm leaning toward getting one of similar price/quality...the Soundsmith folks seemed to steer me towards the SMMC1 or SMMC2 as significantly better than the Denon (for more $$$). I had thought that Soundsmith might have steered me towards Denon mods, but they didn't. In this crazy world of high end audio, I'm thinking of roughly $1,000 or less (including discounts). I'm not sure...but my impression is that after this price range of $700 to $1000, one starts to get diminishing returns in cartridges...not sure. The most expensive thing to do in audio, however...I think is getting a case of upgrade-itis. I'd rather spend a little more than the Denon so that, within the next five years or so...I don't feel the need to upgrade as I move up to a better table. Seperately, I like the idea of getting an MM cartridge...just for the sake of getting a different sound...should be fun. Has anybody tried the Cartridge Man Music Maker?
