Sound Lab vs Magnepan 20.7

Larry, you should come hear them anew. The PX technology and some other improvements came along after that.

I have the U-1PXs in a large purpose-built room. The last weekend in June I'm having a special event you might not want to miss.

Mgattmch,
Brian Zolner, president of Bricasti Design, plans to visit for demonstrations of the M1 DAC and M28 amplifiers on Saturday June 27 and June 28. Anyone interested in attending is welcome, but registration is strongly encouraged since space is a bit limited and we anticipate a full house.

Larry, come on up from Louisville. There will be no shortage of bass nor volume capability with the conservatively rated M28s. It could be a religious experience :-)

Didn't know you had moved. Well, late June in Chicago is a whole lot nicer than in Florida :-)

Johnnyb53, the technologies of the speakers are entirely different. Planar magnetics with voice coils glued to the membranes with permanent magnets running the height of the speakers plus ribbon tweeters versus full range electrostatics with membranes with a light magnetic coating and a charge applied along with insulated stator wires on both sides of the membrane which are driven by the amplifier via step up transformers. Entirely different. And then there are the radiation pattern differences, i.e. flat diaphragms versus stepwise faceted panels which effect a virtual line source with a figure-8 pattern.
