Avalon: Eidolon vs Opus vs Opus Ceramique

Hard for me to imagine any Avalon product described as sounding like Cerwin Vega. Imaging problems can be due to any number of factors. Any full range speaker (of which I certainly believe the Eidolon to be) will be more critical of room placement and associated equipment than those with limited bass extension. Also, the Eidolon requires significantly more break-in than the 300 hours discussed in the owner's manual. You can hear the difference between 1,000 and 500 hours easily. IMO this is the single largest reason for sub-optimal demonstrations of Avalon products (in particular the Eidolon and Opus).

A familial quality among different speakers from a single manufacturer is not a unique trait. These three speakers share the same midrange and tweeter drivers, so one would expect a particularly strong resemblance among among them. I am interested in in comments elaborating on the relative merits among them outside of bass response. I don't think the same can be said of the other speakers in Avalon's current product line (i.e. Eclipse Classic, Arcus, Avatar) as these are 2-way designs with vastly different crossover topologies and drivers.
