Its hard to believe there is a gain issue, I ran my Blue Point Special with 50db of gain with no problem. On the other hand perhaps there is an issue with this amount of gain into that Rotel pre stage.
Sbank, the Dyna 20x comes in a high and low output version, 2.8mv and .3mv respectively. The Ear should handle the low output version just fine. Sinisterporpoise should get the low output version, this could very well solve the overload problem as well.
Sinister, you could also save yourself the hassle of having cartridges installed for you, learn to mount them yourself. Get something like the DB (I use) or many other fine ones and practice with your lower value cartridge, or buy a real cheapy for practice. Its not rocket science, just need a lot of patience and a steady hand, and some guts when you have a real expensive cartridge.
