As a dealer I have a lot of experience with the 82's. It's definitely a FUN speaker for sure! You are thinking correctly in that the Pass Lab or other high current amplifier will help the 82's. Especially, at low to moderate volume levels. As a Sherbourn dealer as well, their amps are quite beefy, but the monoblock amp you have is not the greatest compared to the Pass Labs, Bel Canto, etc.
Here are some other amplifiers that would work great with the 82's as well.....Parasound Halo A21 and Bryston 4B-SST.
