Monoblocks or Bi-Amp


Hey guys,
I'm doing some planning for my future upgrades. I have recently moved to Tubes from SS and was wondering if I should get some Monoblocks or bi-amp my speakers. I was considering the Rogue M-120's or the Rogue Tempest with an extra Rogue Power amp. Or even a SS powerhouse for the bass modules and the tube integrated for the mid and highs.

What have you guys tried and what was the best combination?

System:
Cliffhanger Audio CHS-2 W2 (88db, 4ohms)
Rogue Magnum Tempest 60W Tube Integrated amp
EAD Ultradisk 2000
Virtual Dynamics Ref. Shotgun Speaker cables and Interconnects.

There is 1 advantage of Mono blocks.Short runs of speaker cables.This is a plus.With the Tempest adding a 88 is a very nice option.
Speaker cables draw power & the longer they are the more power they draw from your amp. Larry w.
Well Lwin, that makes lots of sense. Well all the high end guys have monoblocks, so that seems to be where it's at.
Something to shoot for next term. Thanks for all your suggestions everybody.
