I was looking for concrete specs, though. There is a limit for any headphone where it doesn't need more power, and also a limit where more power could damage the drivers.
Haha! I wouldn't be surprised if you came here because I did. XD
For future reference, electrostatic headphones require either a dedicated electrostatic headphone amplifier (not a conventional one) or an electrostatic converter connected to a speaker amp in order to use them at all. I'm sure all three headphones offer unique things, and I'm interested in them all, but I need to factor everything into whatever budget I have when the time comes. Ironically, it may cost me less to get an SR-009 system than the HE-1000, if it needs much more power than my current amp can provide. Imported from Japan, the SR-009 and STAX SRM-323S amp are less than $3,400. If the HE-1000 launches at $2,500 and I need a much more powerful amp, it would cost $4,199 to get it with the Schiit Ragnarok. I'm assuming the EF-1000 would be far costlier. Of course, a TOTL electrostat amp would be an extra $4K+, but it's not necessary.
In my prior research, I saw your post:
Would you be able to elaborate upon this?
