I have mixed both electrostatic, planar and dynamic design.
I have magnepans .05/mglrs-1, OHM'S walsh 2 and 2x0, acoustat spectra 33, eminent technology lft-8a with the push pull, klipsch ss-3 surrounds, dcm 1515 subs,RCA and OPTIMUS lx-5,77 linaeum tweeters for rear/center, even an srs labs klayman signature flat panel. also Wharfedales, yamaha,klipsch and RCA linaeum for center and surrounds. All of these speakers with dakiom stabilizers and BBE sonic maximizers, carver holography, acoustic research spatial enhancer, srslabs enhancer, dbx range controller, peavey kosmos for subs. I DON'T LEAVE ANYTHING TO CHANCE. a COMBINATION OF PLANAR,ELECTROSTAT AND DYNAMICS is always the best method.
i have HORNS even from my klipsch and yamaha. YOu talk about overkill? carver amps/preamps and even compressors and equalizers. MIXING designs and utilizing all at the same time is always the best approach, costly but not really since some of you will spend $20k to $225k for an electrostat or dynamic...
