Urs Posted February 17, 2023 Report Share Posted February 17, 2023 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 Urs Quote Link to comment Share on other sites More sharing options...

Thanks & Regards Urs 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. Quote Link to comment Share on other sites More sharing options...

spritzer Posted February 18, 2023 Report Share Posted February 18, 2023 Anybody claiming that Stax bias voltage needs to increased, immediately file that with "doesn't know what the fuck they are talking about". 4 Quote Link to comment Share on other sites More sharing options...
