Thanks for all the info Satie. I will begin looking for the amp and let you know if I find something of interest. I do have the ADA Audio Designs Associates PF-200 which is MOSFET and will go down to 1/2 ohm. I had a nice conversation with the factory and the amp's designer and he stated that the amp is happier when it is really taxed to a lower ohm load, so I don't think there would be a problem in that area. If I used it for the tweeters, then I could purchase something for the midrange, which may be less critical. What are your thoughts on that approach?

That is perfectly fine.
The midrange would require higher power than the tweeter, particularly since you lose some efficiency from the use of a foil. You would want something rated at least 100W into 4 ohms. You definitely can use the better class D amps, including the BelCanto designs. And you can add in the Tweakaudio/EVS modified nuforce 8 and 8.5 amps to the list in addition to the ones already mentioned. The Wyred 4 Sound ST or STI 250 would also be very useful here.
There are the NAD 208, the Parasounds - the old 2200 (not the "classic" current production) and the A21, The Jungson 88 (its integrated so would have a very handy volume control for PLLXO down the road).
I should add the PSE Studio V and a little less so the Studio 4. The hybrid amps from Monarchy audio, Counterpoint hybrid amps, particularly the Evolution series, and Vincent hybrids. The Musical Fidelity A3CR and 1008.
Again, go over my recommendations from prior posts, I put together a number of lists for various price points.
