Tube Monoblocks for heavy music on Khorns


What tube monoblocks would drive Khorns the best for big bass/heavy metal music? I obviously can't go the SET route for the BEST sound. I was thinking about some BIG monoblocks to help the Khorns 15" driver REALLY move. My room is small. I could even experiment with adding a large sub like a Velodyne HGS18 in the future, too. However, price is an issue. Another interesting Idea, what horn speakers can really compete with Khorn for around the same money for reproduction of bass, Etc??

No sub should ever be necessary.
I found that my 100 watt threshold amp had tons of bass at any volume.
Many years ago, while being interviewed, Paul K, stated that Mcintosh amps were a perfect match for his horns. I'm thinking MC30's? A classic combo.
1- Khorns
2- tube amp
3- heavy metal
4- small room

IMHO, pick any three. I suggest that you eliminate either 1 or 4.
I'm with Br3098. I had my KHorns in my 12' x 13' room and they are just too big. I found that they need room or that squaker makes your eyeballs bleed when you crank it up.
Out in the big room they are a much better fit and can play loud and sound good.
What about the hybrid (Tube, Tube, SS) running active with crossovers, slopes, delays and equalization done in one digital to analog conversion. This is done with my Apple Minimac and Apple Firewire compatible TC Electronic DAC Preamp?
