Stax SR-009 help

post #1 of 18
Thread Starter 

Hello Everyone,


I have been using Stax SR-009 - Woo Audio Wes Combo for year  at least. Suddenly, I started to have a problem with my system.

I use either XLR  or RCA connection, no sound coming out of the Stax, only noise coming out or the right channel.

I am not sure if it is a problem with WES or Stax.

Does any of you guys who lives in Los Angeles area has Stax amp and headphones?

Any recommendation where I can check my system locally in Los Angeles,

I live in West Hollywood.

Thanks in advance.

Sounds like something has blown in the amp.  The headphones would always make some sound even if the diaphragm was in tiny little pieces. 


There are a lot of Stax owners in your area and I'm sure they'll chime in once they wake up.

Thanks a lot for your reply, hopefully someone will break the silence.

If you say it might be an amp, then I have to find any electrostatic amp to try Stax with.

Thanks again.

I'm sure it's the problem with your amp too.

There will be several electrostatic amplifiers at the LA meet next month.

I live a good 70 miles from you (Redlands) and would be happy to let you listen with mine, but wont be able to for 2 weeks.

I would appreciate that.
It would not be any problem for me to wait for several weeks.
Then I can bring my system to share my listening my experience with you.
Let me know at innalnvy@yahoo.com
Thanks a lot
P.S. Could you tell me where the LA meeting will be and when?

Thanks again.

Since it is the Help area:


Can the 009 be driven from the speaker taps a 125WPC SS or tube amp? (Of course, with the correct cable alterations.) Thank you for your consideration.

Without a transformer and a bias supply?  Then no... not a chance.

Thank you. My confusion regarding this 'phone is that I powered Magnepans with Pass 600 monos and thought the Stax phones were the same technology.
Appreciate the education.

All Stax headphones are electrostatics so they need high voltage to polarize the diaphragm and high voltage music signal to drive it.  You can use something like a SRD-7 Mk2 to drive the headphones from a speaker amp.  Stay far away from the Woo Audio WEE unless you want to burn up your amps.

Spritzer, thank you for the advice about the SRD-7 Mk2. A couple of questions, if you don't mind:


1. Are these units currently available?

2. In your opinion, is the SQ compromised?


Best regards.
