I have only initial impressions of Clarisys.
As far as Pendragon versus Clarisys I have the very preliminary sensation that Clarisys might be even more differentiating of different recordings than is Pendragon. Clarisys is at least as transparent and at least as resolving as Pendragon but with no edginess or brightness or any frequency response anomaly I can discern.
I continue to think the Gryphon powered woofer tower is completely brilliant. I'm not sure anything can better it from 20Hz to 200Hz. Of course dedicated subwoofers like Goebel Sovereign and REL No.32 6 Pack and Wilson Master Subsonics should better it from around 30Hz on down to the infrasonic region. If Elliot dropped two Sovereigns into my Christmas stocking I wouldn't turn them away.
From 20Hz to 500Hz the Auditorium overall is a more consistent and satisfying and relaxing and natural experience, because there is no anomaly in any crossover. It's very nice and satisfying to have one 20 Hz-capable driver covering all the way up to the lower midrange.
Piano sounds completely amazing, maybe even as good as any big front-loaded horn I have ever heard. It is similar to Magnepan bass in sonic concept, but significantly more powerful and impactful, and maybe more resolving.
During the listening session on Saturday somebody put on an electronic music track via streaming. There was a very low rumbling sound which the commenter thought was around 30Hz. The commenter thought that it sounded like the ribbon woofer panel was bottoming, so loud and strong was this rumbling sound. Someone else in the group volunteered that he was very familiar with this particular recording and that that is exactly how it was supposed to sound, and we were simply hearing the speaker reproduce accurately the depth and power of that sound on the recording.
From top to bottom, the Clarisys is truly a full range loudspeaker. And I am somebody who would put subwoofers on a ham sandwich.
The Studio Plus sounded good right out of the box, with no fuss, no muss. There is no edginess, no frequency balance problems, no fussiness. The speaker just works right out of the box.
The critical frequency range of upper bass to lower midrange needs no excuse, like it does on the various Martin-Logans I had my whole life, on other electrostatic loudspeakers, on other hybrid loudspeakers, and even on the Pendragons. It all sounds very natural right out of the box. And everyone reports to me that it will only get better after about 200 hours.
My initial reported positive impressions from AXPONA of last year are confirmed in all respects. Unsurprisingly I like tubes on the Clarisys, and my listening room is the first time I have heard them with tubes.
