Denon made a fine receiver, but it's clearly the major limiting factor in your system. Put the money you're about to spend on a cartridge toward your new integrated amplifier instead. It will be a night-and-day difference.
The Creek Evo is a great integrated amp. But if you like Denon and the Denon sound -- and you clearly must to have stuck with your little receiver for 21 years -- then how about a refurbished PMA-2000R for around $500?
It's extremely well made, very powerful, and has an excellent MM/MC phono stage. You can afford it right now and it will take better control of your speakers, offering enhanced detail, resolution and articulation.

Cartridges are a matter of personal taste. But I don't think any cartridge line offers more bang for the buck than Denon. The $180 DL-160 was a bargain 10 years ago...today, it's a ridiculous value. It's a moving coil that has high enough output that it can (and should) be treated as a moving magnet. For a few dollars more, the DL-103 is a low-output classic and the DL-301 for $349 is a steal as well. Both will work fine with the Xpression's arm and the PMA-2000R's built-in phono stage.
The Audio-Technica AT-150MLX will offer you a boost in treble detail but it can sound a bit shrill to some ears. I also think the much less expensive AT-440MLX offers 90% of the 150's performance. You might also look at the $100 Ortofon 2M Red or $200 2M Blue.
But...deal with the amplification first.
