Yes and no. For the most part you are correct. As there have been improvements in dynamics and such with the ML line, I still think one of their most musical sounding speakers were the SL3. Depending if you have a moderate sized room, and with the right equipment - they will sing. Looking at your McCormack upgraded gear, I think these would be a great fit with you system. Again, however careful placement (as they have a backwave) is needed. Expect at least 3 feet out from rear walls in general.
I have used the SL3's in the past with a McCormack DNA-2 Deluxe which was a very nice combo. Feel free to shoot me an email if you want more info.
