Alsyvox is in MA at Dr Vinyl.
For me personally, panels do still have a magic all their own. Cones have come a LONG way and have their own magic as well. But I still find Apogees to have a special place in the halls of audio...and if the Alsyvox is essentially a better, stronger version of those...then, for me, they do indeed have the ability to command competitive prices with established designers. The one yet-to-be-proven element is reliability and servicing. If they cover that, good to go!
For me planar magnetic speakers represent the absolute pinnacle of sound reproduction.
They are not necessarily the most euphonic of beasts. But in terms of what the can reveal of the input signal they have no peer.
People think electrostatics are transparent. But they are not as resolving as a good full range planar magnetic. To think or say so in my mind is mistaken.
I like this range of speakers because it is a serious attempt at doing the best that can be done.
But it comes at a high price. High efficiency is expensive in terms of high power magnets. It's cheaper to use a high power amp than design for a pussy powered speaker.
Higher quality Apogees can and are being built. Mine are soon to get another change. I won't say upgrade until I have heard the results. But it is something I have pushed for and in terms of durability (and hence longevity), rigidity, resistance to climate (humidity mainly) but mainly precision it is a step forward.
Accuracy of manufacture/tolerance is of utmost importance. These days with CNC machining available at reasonable cost there's no excuse to be inaccurate. And with large diaphragms and critical magnet to ribbon spacing it's a massively relevant factor.
Anyway, I'm just about to listen to this video on my own planar magnetics, then try the original recording. Bit of fun...
