I don't have any experience with the Denon and Oppo units but would like to provide some hopefully useful input for you.
If you have 75 SACDs (I'm jealous since I only have about a dozen but building), and you're willing to spend some $$$, consider the NAD M5 Master Series multi-channel SACD player at $1799.00. To have an M5 is one of my goals. Right now I'm using a Marantz DV6001 universal player which plays multi-channel SACDs and it sounds fabulous. I can only imagine how much better the M5 will sound. If you're coming off a highly expensive Tri Vista SACD player, how much are you willing to spend on a replacement? While I'm sure the Denon and Oppo units are great, do you want to move up a notch? You didn't specify what your budget is. The M5 has received 5 star reviews and is supposed to sound superb.
