Looking to upgrade my F/C/R bookshelf home theater speakers. Currently using NHT SuperZero with a Denon X3600H. Lots of love here for the Debut 2.0 but don't hear much about the new Uni-Fi series. Any opinions on the cost/value of the Uni-Fi's over the Debut 5 or 6 series? BTW I don't have any way to audition locally or I would.
