1/2 stack is the way to go. I'm loving mine. Its a single channel w/ a drive switch - so I'm getting used to it. I'd preffer a dual channel head, but for the price I paid, I'll work it out! $990 off of $1800 was a pretty good deal. I sure miss my Crate Blue Voodoo though - that was a killer rig. I've heard good things about HK but never used one.
