Voxativ and Charney (with Voxativ driver) are among the better full range systems I've heard. The best full range driver I've heard is probably the old Jensen/ERPI M-10 field coil driver. But, even with this driver, I prefer the sound with a tweeter on top (the M-10 run full range with a simple 6 db/octave high pass to a tweeter, preferably a 597 field coil tweeter).
I heard a friend's home made SIT amp that utilized the First Watt schematic. I really like that amp. I heard it on a custom-built horn system, so I don't know how it sounds in a system that is harder to drive. I would wager that it would work well with Audio Note speakers which are somewhat efficient and are easy to drive.
