I am about halfway through building a sound system. I have a Marantz AV Receiver, Martin Logan Motion 35XT left & right, and Dynamo 1000W subwoofer.
I am still saving up for a Martin Logan 50XT center channel, but found a deal for some Martin Logan Preface standing speakers. The Preface line is now discontinued, but they look decent for someone not trying to spend crazy money (understanding that in most of the world outside of America, just owning any speaker is a crazy luxury). Would it mess up my system to venture outside of the Motion Series? I'll use the same system for music and movies, with the eventual goal to build a surround sound system.
Here is the Preface speaker spec list:
