Baddabob,
I have had a pair of Merlin VSM-SE and VSM-M hooked up to a Bryston 4B-ST amp and, as Bobby said, it just was too damped in the bottem end. The Bryston worked wonderfully with previous speakers (Gershman Acoustics Avant Garde RX-20, Revel F-30, Paradigm Studio 60 v2) but just not with the Merlins. Sold the Bryston upon Bobby's and seemingly everyone else's recommendation and bought a used Belles 150A Hot Rod amp (~$700 US). Solid state, 125 WPC, MOSFET transistors.
Much better fit, and less money to boot!
From a fellow Canuck,
