ha - upon inspecting the internals, i found 8FQ7 tubes instead of the 6FQ7 tubes they're supposed to come with

Yes, I have a 007tA from Japan with 8FQ7s. See the last post on this page: https://www.head-fi.org/threads/the-stax-thread-new.223263/page-151

Looks like you've got a rarity on your hands.

whoa, that's interesting. thanks for the link! i was searching for any references to it but only found a couple listings of 007t's with them

I am very surprise to see you using STAX SRM-323S? (the small stax amp on your table) how can that little thing manage to drive any of your totl electrostatics?

Nope, those are SRM-252S, SRM-212 and the rare SRM-X Pro on the desk. I got no space on the small desk.
Move the KGSSHV on my entertainment unit in my small room.

 

[chocolates]

that's a nice collection! i think i spy an 007t?

do you have a preference among them?

 

[Mach3]

Strange but they all sound different from the baby energizer to the KGSSHV. All the tube have a slight more fuller sound to them like the 007t and the SRM-600.
KGSSHV has the clearest sound of them all with plenty of power.
Preference are tube with leaner sounding Stax like the L300, SR-009.
Other like SR-007 sound better with the KGSSHV

Really? I prefer my 007 on BHSE and the 009 on KGSSHV Carbon...

I haven't heard them on the carbon or the BHSE so I can't comment, plus misses don't want me to get anymore gear. So will be getting rid of a few things before I can get the T2

Good lord, are those Stax ELS-F81s?
Also, nice to see another Quad ESL 63 owner here.

 

[Mach3]

Yes, they are the super rare F81. I was planning to get the Quad 57 & Quad 63 as I just think they are the most natural sounding speakers. I got lucky found a excellent condition F81 so ended with that and the Quad 63 instead. They pretty much compliment each in term of different genre.

whoa, didn't even notice those! must have cost a pretty penny

I think my 007 is even smoother with the BHSE which defiantly don't sounds quite like an electrostatic at all but with all the might of the electrostatic magic. Regarding SR009, kgsshv carbon seems to give a little more bass and treble extension, well tamed highs and a bit better in overall resolution compare to the BHSE, so its seems to be a better match for the 009. But both amp are so good, so I am selling my Stax SRM727A which is decent with the 009 but not satisfy when pair with the 007 at all. again this is to my ears.

that's lots of speaker, how many speaker amp is there? I only got the Martin Logan Summit-X electrostatic speaker but is no where as detail as my STAX SR009 despite its price.
And my long forgotten monitor audio pl100 in the living room...

Bought it off a senior on gumtree who was cleaning out his shed, he just wanted gone as he no longer had time to enjoy them.
I just saw the Stax logo on the ad and enquire how much he wanted them for.
The asking price was less than a third of what I would have paid for a fully restored Quad 57.
I figured if it need the drivers replaced/restored it would still be more cost effective than the Quad 57 which was fetching 4-5K USD
They worked fine when I got them home, but due to age was getting even more inefficient than their stated spec of 73db SPL.
So they are extremely hard to drive, very hard to find an amp that can drive them properly.
Best amp for them is the legendary Stax DMA-X2 (super rare in working condition) I think I've only seen 2-3 in the last 25 years.
Anyway I got in touch with Kent from ElectroStatic Solutions who was an expert in Stax and Quad electrostatic speaker.
I got him to restore the panel to it former glory and got advice to improve the RC board and upgrade the power board.
So it doesn't zap the diaphragm and burn a hole through them when over driving them.
Kent charges are very reasonable, $700 for both panel and shipped back to Australia, which is like halfway across the globe.
Currently can output around 90-92dB with 75 watts on my Primaluna tube amp. A bit more after upgrade all 8x EL34 to KT150 100 watts.
After finding out about Stax F81 and the Stax DMA-X2, made me realized that Stax was so far ahead of their times.
Turn me instantly into a die hard Stax fanboy. #StaxBro

Sent the detail for the voltage selection for you already with photo.

Besides the electrostatic the other two in the photo are ProAc 1sc & ProAc Studio 100. There 3 other in storage as I don't have space (floor stands) ProAc 3.8, ProAc 2.5 & the Rogers LS6a which I'm trying to sell as it's similar to the Studio 100.
Amp is only the Primaluna, Beta22 surprising can power the ProAc 1SC and Studio 100 to decent level and a California Electronics 200 watt power amp.
