What is the warmest receiver...

Rotel is the only "warm" one in the bunch. I can't complain about Denon sound but if you put bright sound into it, it will come out bright.
You may have to look into some british integrated amps?

Homer, you don't know how right you are. I recently got a tour of WQED pittsburgh, FM 89.3. I couldn't believe it! Their reference speakers in the studio were B&W 801's , yet they were using dual sony single bit 300 disc changers for air play. Not even an external dac. They were so proud that they were in the process of putting everything on a hard drive to save efforts and the fact that they burn up 300 disc changers. Wow, what's worse than a cheap 300 disc unit? How about using them to compress the recordings onto a hard drive and really lose the resolution.
