I bet they sound great with the Levinson amp (also owned a 23.5 in the past although I was driving the Gems with a Krell FPB-300). Are you using the Eddie Current as a preamp?
Good luck with the room treatments. They can really provide a nice improvement. I'm a fan of diffusors behind the speakers. With the rear-firing tweeter on the Gems, this can add a lot of airiness and depth to the soundstage.
