Low Output MC recommendations?

Hello all,

I'm completely enamored with the sound of my Denon DL 304 Mk II, and have had no desire to replace it for the last nearly 3 years. I keep wondering about upgrading, but since Denon doesn't make anything higher up, what low-output MC Cartridges can everyone recommend? I'd like to keep the same sound signature, just "more" of everything.

I've experimented with 4 different phono stages, and settled on one that provides maximum flexibility, and is a synergetic match with the Denon (and the rest of my system).
FWIW, the 'table is a hot-rodded Project Classic. Amp is the Kinki Studio EX-M1+ and the speakers are Wharfedale Linton Heritage 85.

My listening is %70 Classical, %10 Jazz, %10 Soundtracks, and %10 Rock/ambient.

Thanks in advance!
