I have heard good things about the bass control and extension of a good 845 design, such as the deHavilland. It is one of the few single-tube amps that can supply enough power. However, driving Maggies with it is another thing. I understand that they are a hard load for any amp. It's hard to believe that it will have the guts to be loud and have good bass control.
Anybody out there use tubes with Maggies?
