Waking the thread from the dead ...
 
My exstata gave me a shock some days ago!
 
I was listening to some music (moderate levels) with my Lambda Pro when
suddenly the sound started distorting on the left channel and I got some
deep hum too.
 
Unplugged the phones of course and tested them on my srm xh where
they worked properly - so the extata seems to be the problem.
 
I ran through the setup again today and checked all the voltages and
found nothing too alarming. Offset was about 5V on one channel, what
does not seem to be critical (adjusted back to below 1V nonetheless).
 
Now I'm kind of scared to plug in my phones again since I don't have
any clue where the problem might have been.
 
 
Any Idea?

Thanks for reviving this thread. I'm an owner of an Exstata that I bought from Mjolnir Audio last year which is solid state and has an upgraded power supply. I've never been able to find out much info about it, and bought it as an upgrade for my stock Koss ESP energizer.

i was wondering how this model compares to the stock Stax amps and some of the Kevin Gilmore designs, as I'm probably going to buy L700s at some point and want to get an idea of what kind of improvement I might get with something like a KGST, etc.

Sorry to threadjack Sathimas. i'm hoping enough people see this thread again to answer both our questions.

Hello,

Have been thinking of making one of these amps for a while. Now have the time and would like to do so. Perhaps I am missing it, but haven't found yet where I can purchase the PCB's. Are they still available? If not, does anyone have the gerber file so I could have some made?

Currently have the Koss ESP950 headphones with a much better than original power supply.

Any information would be appreciated.
Regards,
Greg
