There are plenty of affordable high output Tube amps out there.Consonance Cyber 800's,Mesa Baron,Rogue 120/150/88 & 90 to name a few.I've also owned several "Tubey" solid state amps which are capable of driving the 10t's and just about anything else.They include The Muse model 160 series II,Plinius SA 100mk.III.and the venerable Hafler XL600.The Aragon 8008BB is also a very nice sounding amp that will dive whatever speakers you pair it with.
BTW,The VS VR-4SE is an amazing speaker!
