Happy Holidays Buyfast1.
I have used a number of MIT p/c's on my Lexicon RT-20. The further up the line the better the sound gets with a good player, which I believe your Denon is. I have obtaines a surprisingly refined sound from the RT-20 using the MIT products in my Spectral system.
I suggest looking for the best bargain available from the Shotgun AC1 and up. You will gain experience with MIT and be able to sell & buy up as the next deal comes available. If you simply want to "jump in" then I would look for a used Oracle AC3, a simple non networked cord which is exceptional for any component.
If your player sounds harsh I suggest you also try some conditioning and isolation for it. I found used MIT products excellent value. Perhaps the AC power to your setup is needing power conditioning.
