One thing I notice about the kind of speakers that tend to be keepers is that the designers seem to think the speakers are worth keeping in their lineup without radical changes to an original design idea - if you get it right the first time no need a new idea every two years. Vandersteen, Maggies, Merlins, Soundlab, etc. their is a pattern - these companies also seem to last and be successful without design revolutions, but gradual evolutionary developments. I wish I had a chance to hear the Apogees with the right amp at some point.
