The Headcase Stax thread

With no inside pics it is hard to tell but I had the Mk1 and it was utter trash and dangerous to the end user.  There are pics here somewhere of that but yeah, utter garbage

Thanks, I would like to get into stats (particularly the CRBN) but it seems nicer if I can use my existing setup.

Good transformers are a great way to do that and are definitely getting more popular.

Yeah a couple of months ago I posted about the BHSE but unfortunately the seller went MIA so that didn’t work out lol.

I am a bit concerned my main amp, a SET 2A3 amp is a bit on the lower power side. In my experience it can drive the 32 Ohm transformer for RAAL Immanis fine but I don’t have much experience with e-stat interfaces.

2-3W or so?  That is very much on the low side but it always depends on overall system gain and how loud you listen.  A Stax SRD-7 Mk2 should work as the ratio on those is on the high side.

Yeah, around that range, if I'm not wrong it's about 2.5W into 32 Ohm load. I noticed that you have a Sansui variant of the SRD-7, will that work nicely as well?

[spritzer]

It should work, the ratio is a bit higher than the Stax ones.  Ultimately it's not about power but voltage in the system or voltage swing rather.

What do you think about these drivers?

can they have good sound?)

[chinsettawong]

They look nice!  I'm sure they can produce good sound.

Hi all.  I've been trying to find measurements of electrostatic amplifiers - other sites typically don't know how to measure them- so looking for HD & IM distortion measurements, max voltage swing, SINAD, and also maybe slew rate.  I've spent some time looking around on this site but haven't stumbled across any yet... if someone could point me to a page here or maybe a site like Mjolnir or some other place that might list some measurements.  I just want to see what's considered good for electrostatic amps....

 

Thanks!
