Tubes and Tekton's

I play Tool, Disturbed, Godsmack, Volbeat, etc. on my Tekton Enzo XL with tube preamp and SS amp.  That kind of music will need a little higher power tube amp or a tube preamp + SS amp.... they sound amazing though - cannot even imagine the Double Impact.
I am playing to EXTREMELY loud levels (near concert) with the tube preamp, a small 55-watt B&K solid state amp, the Tekton Enzo XL and a pair of HSU VTF-15H v2 subs.

Recently sold my Enzo XLs and switched to the upgraded DIs and also added a pair of stereo Tekton 4-10 subs on the side of each DI tower - photos in my virtual system.  Changed x-over point on the HSU subs to really low, like 30hz, let the Tekton 4-10 sub towers in at around 50hz.
