I would not run the lowthers full range

There is nothing good to be had by trying to force the paraglow and lowthers to handle much below 100 hertz (really anything lower than the horn's cutoff IMHO). So you really need two crossover points, a high pass to the paraglow/lowthers, and a low pass to the sand amp/414's.

Marchand sells a very low cost solution if you don't mind doing a little soldering and building your own "box". Look at the XM1. Their power supply is adequate but you could build something a lot better from scratch. If looks matter you can consider the XM9. Marchand is a lot better than the options you mention. If you really hate the idea of op amps on the lowthers consider the XM46, a passive line level crossover. But it is a very tough load for a tube based preamp. I'd ask Paul Joppa's advice (a step down transformer after the foreplay is one way for example).
