Preamp/AVR suggestions

[kareface]

I have some really specific conditions for a preamp or AVR with preamp options and I wanted to see if anyone had any suggestions. I want to be able to set the crossover for each channel independently (the rears in pairs of course), preouts including ones for bi-amping the front left and right channels while still using the 2 rear channels, HDMI switching, 2 LEF channels would be cool but not a deal breaker, it would be nice if I could drive the surround and rear channels with it, but if it's got all the other options I'd be happy with just a preamp. The last one is something I've only found on a few amps, but they lacked other options or were a little to costly for my taste. I'd like the ability to toggle calibration settings with out having to manually reset them each time. Levels, equalization, crossovers, anything that might change the nature of the sound produced by the amp. Preferably if I didn't have to go into menus to do it. Any suggestions would be welcomed.
