HD350 and 1001RB-II (the newer 700W one). I almost bought a Gorm, but the weight turned me off, plus I like the flexibility of having a head I can do whatever I want with regarding speakers. For example, I just picked up a pair of Aguilar GS112's, as I'm trying to go to a "high power micro-rig" kinda' thing. My other cabs are a pair of Eden 210XLT's, which I love, but they're a lot bigger and heavier.
IMHO, even tho the EBS is only a "350W" head, i'd put it up against any 500W (or more) head any day... PLENTY of guts, and so light weight! As a side note, I got it kinda' unexpectedly. I wasn't even lookin' for a head, but someone had this one up for sale at $600, so I couldn't pass it up.
In case yer interested, here's my current "micro powerhouse". I really love it!
