Bill, its worth trying the PLLXO, for sure.

I'm using a 1st order PLLXO (which is silly simple to build) for a CHR70 in a sealed enclosure with Eminence 15As in an OB (ala MJK) and am very satisfied. I've also played with a 2nd order based on those same formulas. Even with reversed polarity on one of the outputs with the 2nd order, so far still I prefer the 1st order. You can cobble up a test with a solderless test board and a few really cheap components.

Of course, going this way is only feasible if you have two amps...

I've been using cheap components so far but have some "higher quality" ones on the way and have built a A/B test rig to see if the sound quality difference is actually significant.
