After reading some old posts on this forum I've decided to start looking for a second hand Lexicon MC-1 but was hoping for a bit of advice on a couple of points before I part with any cash. My current set up includes Monitor Audio 8i main speakers bi-amped by Arcam 10ps, Mission 75c centre powered by the third channel from one of the 10ps and Mission 78ds rears powered by an Arcam 290p. Do you think this will work well with the Lexicon or should I be looking to upgrade this stuff too? I think the speakers will be changed in time anyway but I was hoping to stick with the amps. I was also wondering if there's anything in particular I should be checking for when looking for a second hand MC-1? Thanks in advance for any advice you can give.
