Just an interjection - I think you'll have more trouble getting wide range from your speakers than from your amps. It has nothing to do with your question about amps, but it does go to the point. If you're worried about 25Hz from tube amps, I'd probably be more focused on the speakers than the amp. Most high efficiency designs are 40Hz and up, and many are more like 60Hz or 80Hz up.
