STAX QUERY - variable Polarization Voltage ?

[Urs]

Dear all,

I’m currently considering to  up-dating my STAX-compatible  HeadAmp with an extra-option of  a variable Polarization Voltage .

Reportedly, the SR-007 Mk2 may benefit from such a higher voltage

Who has experience with such a feature ?

Thanks & Regards

No... just no.

if you make the bias voltage too high there will be a spark from the diaphragm to one of the audio grids. This will burn holes in the diaphragm and result in a very costly strip down and repair not to mention the possibility of damaging the Stax amp. Stax choose 580V bias for a reason it works and is reliable.

Thanks a lot  to both of  you !

Case closed !

Anybody claiming that Stax bias voltage needs to increased, immediately file that with "doesn't know what the fuck they are talking about".
