Up for a sale is the heaudio jade electrostatic headphone and the heaudio tube amp.
the amp is the one heaudio used to build/fine tune the heaudio jade, i assume this amp play a lot in influence/shape how the final sound of the jade like and it probably perceived as good synergy with the jade by the builder? very rare as it is never made into commercial release, took me more then a year to hunt it down.
some detail about the amp:
it's a full differential balance 3 stage all tube amp, with 12au7 as first stage gain，12at7 second stage for push pull, 12bh7 final stage to drive headphone, capacitor coupled in between each stage. has balance and single end input, stax 5 pin output, it's a 580v pro bias , can be used to drive any pro-bias stax headphone. the amp only take 220 v line input.
the heaudio jade headphone is terminated in stax plug, not the 5 pin neutrik xlr plug, the headphone is in excellent condition, box included.
wasn't thinking about selling this combo in the past due to it's collection value, but an opportunity to expensive diy project had come up making me hard to resist, need to raise fund for this diy project.
i have no idea how much this combo cost , as none of this amp was put up for sale, but feel free to pm me an offer, all reasonable offer will be considered. thanks for looking. :)
