I do not know much about how the Stax pro and normal work. I assume the cable allows to convert from normal to pro. I have a few pairs of Stax normal but trying to get rid of all Stax normal amplifiers. Please let me know if there is a way to convert from normal to pro.
Thank you very much for your warning and advice.
Thank you very much for the advices from several Head-Fier for not using the cable to convert 6 pin normal to 5 pin pro. Otherwise, I would use the cable to connect the normal Sigma HP to the BSHE. I hope some day, I can hear the sound from the sigma normal from BHSE and KGSSHG.
