I assume it's main only, and no battery, but the size looks portable

A late reply

 
My friend recently bought one with the matching PSU, based on my brief experience of this amp, I would describe the sound as pacey, punchy, and damn quick, if you crave smoothness and warmth I would say it doesn't offer that kind of presentation, instead if you like a fast foot tapping sound it would be right up your street.
 
  Adding the PSU refines the sound and the bass response is deeper.

I own the HA-2 with the matching power supply and it is very smooth sounding especially with good cabling. I really like the HA-2. If the new version of the HA-1 sounds near as good then it must be nice. I'm enjoying my HA-2.
