I don't see your post there. What do you mean? What did you say back then?
sorry, I didn’t mean post 106. I meant this is the 106th thing I can say I told you so, that SETs are not going to be required on the pendragon

I'm confused, because I wrote that I don't have the desire presently to investigate SETs that I thought I would have.sorry, I didn’t mean post 106. I meant this is the 106th thing I can say I told you so, that SETs are going to be required on the pendragon
LOL! They'll wear you down. I gaze into my crystal ball, and I see an 845 amp looming up in the mists.
A GM70 at Minimum...LOL! They'll wear you down. I gaze into my crystal ball, and I see an 845 amp looming up in the mists.

Finally someone comments what I’ve been wondering about.12db drop from 2-10K seems weird........
No high power Russian tubes for me -- for high power for me it is Eimac or nothing.A GM70 at Minimum...
Ron ... thats pretty damm good for the short time you've spent !
Has anyone suggested moving the bass towers inboard and leaving M/T where it is .. just to get them further away from wall .. just to delay wall reflections ... esp 250hz
Regardless its looking good

I tend to agree with you re offset woofers as 250hz is in the range where you perceive location ( above 170hz supposedly)Thank you, Phil!
Actually, Don Saltzman suggested moving the woofer towers one foot and two feet behind the ribbon panels. I vetoed that idea for now as 1) the woofer towers don't have the continuous phase adjustment (they don't have any phase adjustment) or time delay variability of Gary Koh's more complex Genesis woofer towers, 2) while I am not terribly sensitive to discontinuity, I am hearing no discontinuity between the towers with them right next to each other and I do not want to introduce any discontinuity, and 3) I consider the first stage done, and I just want to enjoy the system playing music for the foreseeable future, playing maybe only with absorption panels to and fro.
Someday in the future when I have the appetite for it I will definitely return to tower repositioning experimentation.
Now that the 20Hz drop off has disappeared I think that TubeTraps may do a respectable job of dampening the 65Hz peak.
12db drop from 2-10K seems weird........
Well, I doubt that Gryphon intended it, but you have an exquisite instrument for amplifier experimentation. Crossed over at 250 Hz, two thirds (maybe even more) of the power band requirement in the bass and lower midrange towers are already handled, leaving a third (maybe even less) of the power band requirement for the ribbons. Even at a nominally stated line array sensitivity of 89db, you wouldn't necessarily need high power for good results. It also doesn't look like it is difficult to splice amplifiers into and out of the ribbons.No high power Russian tubes for me -- for high power for me it is Eimac or nothing.
I stopped using a mobile phone for this purpose two weeks ago.Yes, unfortunately it seems the mobile phone application is not able to smooth spectra or compute slopes.
I was part of the crew who came by last Saturday. This was a celebration amongst friends for the launch of Ron's new system. We talked. We ate. We sipped. We shared great records and tapes. We had a good time!
What did I hear? A combination of components I've not heard before, all in various stages of break-in, playing in a room that I'm not familiar with. I'm not gonna pass judgment on that.
Some of what I heard was stunningly good. The soundstaging was huge! The orchestra seating of Mehta's L.A. Phil performing Mahler 3rd was precisely mapped across the space between the speakers. Low frequency punch was tight and visceral. On the other hand, with a few tracks, at certain levels, those Pendragons really did breath fire. Ouch. But that'll get fixed. We indulged in swapping acoustic treatments while we listened, and we learned a few things from that. But that's not the main reason we were there.
We were there to celebrate Ron's new system.
Mission accomplished!
