Order TalentCell:

I use a Note9 with Neutron as a Player.
Works great

you really need the 6AH battery for 10 hours of playing time.

srm252 with a decent sized 12V lithium ion battery glued to the top or bottom

it has 280V..

252 is pro bias only.
srm-Xh, Srm212, SRM252 are all pro bias only.
fairly easy to modify if you want standard bias.

Order TalentCell:

And a reverse polarity adaptor to use the supplied cable since the SRM-252 requires a centre negative power supply.

In that case I want 12 hours plus

Sketch of the CCS-mode board for the SRM-600. Moving forward little by little Mr. Gilmore, mr. Lin, thank you!

Finally I developed and manufactured a board for CCS-MOD for my SRM-600. I'm starting to solder the parts

Does such a board exist in any form for the T1 series?

I have not seen a similar board for T1 with mounts on existing screws. But the T1 has a different layout of tubes and plate resistors, so my form-factor is not exactly suitable, you need to develop another one.

do you think it's worth upgrading from the 252s to the 323?

Well it won't be 'portable' anymore, so there's that. What aspect of the 252 are you unsatisfied with?

To explain to myself:
I have already overcome the high-end phase and am aware of the sense and nonsense of high-end devices.
But I have no experience with electrostatic headphones, so I wonder what influence an amplifier can have in this case

Actually has anyone ever done a sound comparison between the SRD-X pro and the smaller stax amps? I have a normal bias SRD-X, somewhere, and the full-sized amps are definitely a lot better in every way. Still not too bad for something running on six D-cell batteries.

Higher peak-to-peak voltage swing, more current, better THD and SNR. The voltage (and power) requirements of the Stax headphones differ a bit, the SR-007 is apparently the hardest to drive. I'm not aware of any objective measurements of the resulting effect. Since you have a 252, I'd suggest taking that and your own headphones to a dealer that has some amps to compare it to. I'd recommend MSP in Cologne, I think the last time I've been there, they've had a 353 and a 007t on display. Alternatively, if it doesn't get cancelled, the German Stax importer is usually at http://www.westdeutsche-hifi-tage.de/, but they are in a noisy shared room on the ground floor.
