Martin Logan Expression 20+ hours--

After 20+ hours the Expressions are breaking in in the usual ML electrostatic pattern.  Bass is more substantial, detailed, and subjectively faster.  There is more mid and treble detail and greater depth of image.

I expect this pattern to continue.  However, time will tell, and I will report accordingly after 40 hours.

Martin Logan Expression 40+ hours--

At 40+ hours break in continues. The occasional incidents of scratchy highs are gone, bass is perceptually quicker, and there is more information about the size of the recording venue apparent.  Inner voices remain quite clear.  The speakers seem louder than their predecessors (Summit X), for a given volume setting.

Will report further at 60+ hours.

   Martin Logan Expression 60+ hours--

At 60 + hours there are no anomalies in any aspect of the Expression's performance.  Bass is quick.  There is no apparent discontinuity between the woofers and the stators.  There is an excellent sense of the performance venue.  Instruments or singers locate clearly but without any sense of isolation.  Highs are clear.  The mids are superior in clarity and definition to the Summit X.

Will report further at 100+ hours unless there are significant developments prior to that time.

   Martin Logan Expression 100+ hours--

 Beyond 100 hours it is probable that the break in process is largely complete.  I have re-eqed the woofers, a process that took about 15 minutes, to account for expectable low frequency enhancement as woofer suspensions loosen somewhat. Highs are clear without in any way being overbearing.  Mids are detailed, and location of instruments or voices is clear and stable.  Everything is quick and realistic.

Summit X, which preceded the Expression, is an excellent speaker.  Expression takes the Summit X qualities to a higher level in all respects.  This is the best Martin Logan speaker yet in this form factor.
