Good moving magnet or cheap moving coil

Definitely the Dynavector 10X4 for $350 or the 20X-H for $525 (not $600 as has been stated in a previous post)

In my experience there is no better cartridge in this price range than the 20X-H, and the 10X-4 is quite good for the money too. We always recommend them to our customers when looking for cartridges at or under $500.

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.
