Anyone Switch from Electrostatic/Planar to Dynamic

Very unlikely (though I never say never) that I will make the switch back to boxes. I have a pair of Apogee Stages and with the stock crossover, there are as many shortcomings as significant advantages. I gutted the cheap capacitors and decent inductors and replaced with NorthCreek Caps and thier 8gauge coils. The improvements were uncanny in all respects. I have owned Proac 2.5's, B&W805's, Thiel 22's and several others and I have yet to hear anything in a box that will change my opinion. The only limitations are absolute SPL levels (the bass ribbon only has so much excusion capability) and even though the lateral sweet spot is as wide as any, the vertical sweet spot is still fairly narrow but not a big deal. They do need current to provide the dynamics and slam that I require/ The ribbons do need current though to provide lifelike dynamics and slam but my Lev 331 really shines there. And considering there is now a source for replacement ribbons and a great usergroup site for information, I could not be happier owning Apogees for the long haul.

Yes Clueless on both counts. I have spent $thousands$ trying to "upgrade" components and cables but I have to say the few hundred $$ I spent upgrading the crossover knocked me out. WAY more than a tweak! George was a great help to me. Being a novice, I liked the information he provides in his website www.northcreekmusic.com especially the info on cascade bypassing capacitors. He helped me piece together the parts list and answered questions along the way. The results were stellar. I've been sharing results with other Apogee owners and I now understand George has packaged a kit to upgrade Apogees.
Years back Stereophile and other reviewers talked enthusistically about the virtues of the Apogee sound but with those kmart crossovers removed and replaced with premium parts I can only imagine what they would have written about them.
