The HPA-1 sounds wonderful. You guys are in for a treat. The HPA-1 is a contender in the solid-state amp space. I haven't done any comparative listening with other amps yet, but that will come. If anyone is in the SF Bay Area and not on the list I will be bringing the amp with me to the meet in San Jose this Saturday, January 30th. I'll post a full review once my time is up.
