I had the Parsifal Encore and they like to have some power 18wpc won't show you the potential of these speakers. You can also get something with a bit of bit as they are naturally pretty laid back.
The Luxman rec is good but after owning Luxman amps for 15 years I can't really listen to them anymore, maybe bored or just wanting something different.
Great speaker give them some breathing room and enjoy!
