In reflecting back on the comments by the Rockport Antares owner with Dart....I have Rockport Merak/Sheritan II combo with Ayre MX-R...works very nicely...while I have not heard Dart in my home I suspect that the Rockport speakers would do well on the deeper power reserves of the Ayre/MX-R...at least from what I can hear...I suspect the amp's head room contributes to the particularly musical/relaxed/natural sound with the Ayre/Rockport combo...I found no objectionable elements to the sound...wonderful low level detail...great image stability...able to handle shifts from quiet passages to loud passages without any sense that the power bandwidth of the system was changing...which to me is a common issue with many combo of tube amps and relatively inefficient speakers....
