I previously used a Jasmine with various 103 variants and it was a nice phono and the de facto recommendation for Denons, but a hundred or so out of your range...
Lately I replaced the Jasmine with an older Monolithic PS-1 phono pre and am happier with its core sound, being more organic and natural with similar transparency and staging qualities. Dynamics may be a bit muted by comparison, but I have an HC-1B psu on the way which I suspect will give the Monolitich the advantage. Give it a look in your budget, I enjoy mine.
My other recommendation would be the Vista Audio phono pre AC addition for $300.
