I've just been burning the amp in, so haven't done any critical listening yet.
From another review I've read, this is one heck of an amplifier. I wouldn't want to comment on its position in relation to the Solo, but it's meant to be very very good! It's a different beast to the Voyager too, so I can only assume it's going to be better for people that don't need battery power. I can't wait to have a proper listen after it's done some more hours!
I'm sorry about the stipulation on post count. I know it doesn't prove that someone is more trust-worthy than another, but there's at least some history within the community. You never know... In 12 weeks time you may have over 100 posts
