I'm running a Crest Prolite 2.0 bridged into either a 4 Ohm MESA Powerhouse 4X12 or 4 Ohm MESA Powerhouse 6X10..
Running it with two Sansamp RBI's, one clean, one dirty. I've never turned my rig up past 1/2 on the volume, and I'm really loving the tone of this rig. The power amp only weighs something like 12 lbs, quite comparable to the Peavey IPR series but with less problems IMO.
