Hi. I´m not familiar with the Marten Design speakers, but I currently have at home Ayon Audio Falcon S and Avalon Opus Ceramique speakers. Although they use the same tweeter and midrange section both speakers sound totally different. The Avalon is EXTREMELY coherent with lots of detail and space while on the other side lacks a deep base line and punch. The Ayon is extremely dynamic and has got a lot of punch but is not as stabel (imaging wise) and not as coherent as the Avalon.
Depending on what you want (to spend) you should probably look as well at the Kharma or Lumen White range of spakers. Both use ceramique drivers as well.
