Product Description
You could keep using the same old headphone technology that you’ve been rocking for years, or you could upgrade to an entirely new approach that yields astonishing results. Forgoing conventional dynamic or planar magnetic drivers in favor of electrostatic alternatives, the STAX SRS-3170 Electrostatic Earspeaker System features a thin conductive diaphragm between two charged plates Read More
can someone tell me what does the transformer look like? i wanted to buy one from either china (220v ) or japan (110v) but i don't know where to get the proper transformer to get it to work in the US
ArTiK_slaughterA very very delayed reply because I just happened to see if MD ever offered Stax.
No, 132KOhms is correct. These are electrostatic headphones. They require very minimal current <1mA but very high voltage >500V to drive. Some of the electrostatic amps on the market go all the way up to 1500V output. If you look at full electrostatic speakers, it's not uncommon to have drivers that can output >3KV at higher current. A regular coil speaker unit usually requires high current and low voltage to drive (<30V & >10mA).
EDIT: Voltage mentioned here are all VPP, not RMS.
tikkytakAccording to me, yes, they are. I tried the STAX after Senns HD 280 PRO, Beyer DT 770 250 OHMs, AKG K612, HIFIMAN HE 400s etc. None can come even close to the sound and detail quality
kartiksathappanThe amp requires 220V. The US uses 120V AC through your wall. You'll need to use the step-up transformer Massdrop provides you.
While you can get a US power cable and bypass the transofmer entirely, if you plug the amp into a 120V outlet without the step-up converter, It will either:
1) not work at all
2) draw 1/4 the power needed, and not work well
