TRUE wattage, not just wattage, and current is also a small detail. The ability to deliver plenty of current means an amp can deliver more than it's rated power without choking. The A65+ is an integrated and does not include any processing or video, so it is less complicated and focuses on the things it is meant to do, not to mention it is 2ch only. Arcam is not building these integrateds to compete with the $300 receiver market either (my friend's A80 cost almost as much as my Marantz 8300). I would take the A65 over most receivers in it's price range

There are tube amps that deliver only 8wpc that will likely perform as well as the A65+.
My Marantz PM7000 is rated at 95x2, but a review showed it to actually deliver 115wpc.
