This is a spin-off from my "Want a little head" thread... What's out there in poweramps that are a "non-standard" form factor? I'm aware of the Clarus, and that's about it. Id buy a Clarus in a heartbeat if they came out with a more powerful one. I'm thinking in the 400W~600W @ 4 Ohm range, and X 2 would be fine, too (always nice to have a channel in reserve, I'm told). I'd prefer not to have to run bridged to get these levels. Is anything like this being made? I know racks are the industry standard, but I'm looking for lightweight portability for use with a SABDDI or something similar.
