Rebbi,
Thanks for the reference. The TAS article notes the CM1 has a sensitivity of 84db. I have listened to them powered by a 50W/ch NAD amp (fairly lifeless and dull combination) and a 500W/ch Rotel switching amp, and the latter really got them up on a plane. For that reason, these may not be the best choice for your application. I suggest auditioning the CM1's through something similar to your PS Audio amplifier in terms of power and current and comparing that to a much higher power unit to see whether you would be under powering them at 70W. I think the Totem Rainmaker (87.5db) or Dynaudio Audience 42 (86db) might be a better match, even running at 4 ohms. Curious to hear your perspective after listening.
