Yes, thank you. I know that. (I have had line source loudspeakers for 30 years.)

Yes, thank you. I know that. (I have had line source loudspeakers for 30 years.)
I'm afraid I've lost track several pages ago of the question y'all are trying to answer. What are you trying to figure out?
I think there is a misconception that Ron is unhappy with the sound of his system with VTL amps, i think he is just doing all the experiments he has been dying to do all these years waiting to finally have a system ! 
And still dialing in everything !

Wow! That’s loud.
I also see that Mr. Cali has the Gryphon Kodo and full Gryphon system now.
Could you see yourself with Gryphon amps rather than trying to match a high power tube amp to your Pendragons?
Manufacturers know about it and usually the sensitivity referred in the speaker specifications is the "equivalent" sensitivity - the sensitivity of a point like speaker that would generate the same sound level at a typical listening distance with the same power. Also , due to the usual more artisanal manufacture of planar speakers most of them do not have the large anechoic chambers needed to measure the sensitivity with accuracy.
BTW, the quadratic drop is only valid in anechoic conditions - the real dependence depends a lot on room characteristics. IMO, most of the time the needed power calculators existing online are highly misleading - they assume ideal amplifiers with ideal speakers in anechoic rooms! Experience and practice is needed in such affairs.
That is too simple given your background.
How far off from establishing yourself at the forefront of classy (Class E power amplification) digital reproduction?
comes to the operating point of the el 34 tube at 430volts 35mA would be described as warm.
at 430volt/50mA it sounds very neutral, high resolution with low distortion. you can tune something like that to your hearing. (430 volt usual anode voltage push pull amps)

I think it's just realistic actual concert level SPL, no?
Aren't we supposed to be reproducing the experience of a live concert?
Yes! I am very happy for Joe, and I can't wait to go over to hear them!
no

I am afraid I don't understand either of these sentences.
You state numerous years in wireless radio were formative to your present state of audio pursuits.
Digital? I won't recite the cadre of names you've recently noted provided a welcome nudge to justify this line of inquiry. Suffice to say the world is going wireless.
Nobody, least of all me, expected that solitary comment to impose on your stated task of exploring the prescribed path one can ease down making/registering acceptable choices at every junction. The entire purpose was to create a sharp, and thus (
) humorous, contrast by drawing a parallel.Not unless you want permanent hearing loss! 95 db (avg., not peaks) is the equivalent of having a motorcycle in your listening room.
I don’t feel it’s necessary to play music in a small room at the same volume as you would hear at an amplified concert or full Symphony orchestra from the 10th row in order to have a realistic facsimile of live sound.
Yes, amateur radio. My prior interest in amateur radio has nothing to do with high-end audio. But it did afford me a basic, if now stale, understanding of grounding, RFI/EMI and elementary electronics.

Perhaps if Google offers a Rando-to-English translator you could run this post through that and let us know the resulting translation. Thank you.
the idea is for the music to become physical. part of which is the PRAT and micro dynamics. part of it is the speakers hooking up in the room. and the source matters too. it need not be loud.
lots of volume should be very sparingly applied. you don't want the SPL's of a large venue on a regular basis. it is important to have headroom in your system and room acoustics. so it can handle peaks properly.
My apologies for intruding upon your system thread to express uninterpretable notions.
Furthermore, I withdraw any mention of digital. Which clearly lacks topical or momentary relevance.
I was thinking Klingon to English translator right before you wrote this Ron ! But Rando to English is probably the more correct translation !

Yes, thank you. I saw that. But I need two matched quads. I don't want to just got a single random quad.
Somewhat one of the Achilles heals where multi output valve topologies are concerned, especially when attempting to match increasingly hard to source and ever more expensive NOS valves .Here the first half Ei kt90
