Good moving magnet or cheap moving coil

If you enough gain the ortofon kontrapunkts are a great match for the Ittok$585 here on A gon. The Denon 103 maybe too low output for your system. Also, they are very low compliance artridges, with the 103D being somewhat higher spec. This means the resonance frequency maybe an issue in the Ittok. With the small signal levels involved in cartridges, these are important considerations.

Pbb is right about the Shure, I replaced an $800 high output moving coil with one and it has a believability about the sound that just seems right.

For $600 or less, you can get one of the top Grado Reference models here in Audiogon. Hard to beat, IMO.

Grados and Linns often don't mix electrically. Caution.

Best MM is the Clearaudio Virtuoso - good price with any trade at the Elusive Disc - check out the site. I own one.
