DWC,
Thanks for the response! I ended up going with the F10. The $169 special on Amazon was just too good to pass up, especially with all the in depth info on this board. It has since gone back to its around $220 price tag.
Gotta say I am happy with it. Its still in break in but the sound is clean, and I get nice "true" textures and tones on the various instruments I have tried to isolate, but curiously not all the time (might have something to do with volume or break in). For $169 - I gotta say I feel like I got a bargain.
But speaking of heat, this little unit gets pretty darn hot on the left side.
BTW - those speakers sound great. That will be my next upgrade. Glad to hear I don't have to shy away from 4 ohms.
Thanks again to all.
