Wilson X-1 series I. The longest most boring one hour listening session ever. No cabinet resonances--can't complain there. But nothing really spectacular ever stood out. Soundstaging and imaging were only mediocre--my little Thiels did a better job on the Q sound material (as did the avalons). Not even worth $10K. "most over-rated, over-priced, over-hyped speaker"
Klipsch Epic series II. $100 in dynamat smoothed out and deepened the bass nicely, and the lower midrage opened up a bit. But the high frequencies still scraped your eardrums (classical sounded horrible). I've never like anything by klipsch. The units maybe worth hearing (that I haven't) are the old school line: klipschorn, chorus, forte, etc. But for the most part they suck.
