I haven't heard the EX-M1+ but I owned the EX-M1 and although I loved 99% of its sound, it sounded a touch dry to me. I replaced the opamps and this helped but my subconscious kept telling me that something wasn't quite right. The best way I can explain it is that it sounded harmonically incomplete or overdamped and as much as I loved the amp I couldn't ignore this trait and ended up selling it.
Once I hooked up my tube amp again, my subconscious relaxed and the nagging was gone.
However, the new owner of the EX-M1 likes it so much that he has now sold his tube amp.
