HIFIMAN JADE II REVIEW
July 17, 2019 § Leave a comment
There is far less to go on regarding the amplifier and what is happening on the inside. What we do know is that it uses a cascode differential circuit of transistors and MOFSETs with an 80W transformer outputting around 1.2W at 1kHz. I would class this as a medium output level solid state amp on par with the 1W into 32Ω Auris HA-2SE for output but much lower than my own e-stats VE Enterprise E Lite at just over 3W per channel.
The amp is also set up with a Pro Bias 540V output so it is compatible not only with Hifiman’s Jade II headphones but also pretty much any electrostatic headphone with a 5-pin pro bias connector.
This is also a single-ended design rather than a balanced amp configuration despite it having a balanced XLR 3-pin input on the rear. It will allow two inputs (dual RCA/XLR) with a switch control and two e-stats headphones can connect to the front at the same time. As a reviewer, being able to compare to headphones from the same amp at the same time without disconnecting and switching is gold.”
