hello
I previously owned a pioneer VSA-EO3 and bought a Denon 1909. I never liked the Denon. When it came to upgrade, I really wanted the Pioneer LX73 (precursor to the 75). I demo'd the 73 and used the Denon 3312 as a 'stalking horse' on the basis that it was the best Denon currently available, so would sound similar to (but better than) my 1909, but would show the LX73's class.
I bought the Denon (much to my surprise!).
Please audition both (and a comperable Yamaha and Onkyo).
Good luck!
