This is a review and detailed measurements of the Hifiman HE6se planar magnetic headphone. It is on kind loan from a member and costs US $1,800. I had previously reviewed the now discontinued Hifiman HE6 so great to see how the replacement performs. The HE6se distinguishes itself with new headband, cups, etc.: Very unusual ultralight "tube like" cable comes with the headphone: It has a clear silicone like outer jacket and possible Litz wiring inside. It... Read more

This is a review, detailed measurements and comparison of Apple's USB-C adapter to the current and last version of Google Pixel headphone adapters. The Apple adapter costs just $9 including one day shipping for free. The Google dongle costs $12. Not that any of these are large by any stretch but Apple's is also the smallest of the three: ​ Oddly there is no apple logo or markings on the device. The others don't have it either but I thought Apple would insist on that... Read more

I bought a Tangent PowerAmpster II. final stage in my small music system at home. My speaker is a Klipsch R-28F with a tuned switch. I had an SDS-470C final stage before it, it had no problems, only its performance was excessive. The Tangent PowerAmpster II sounds very nice, but when it is turned on, it has an audible noise in the default position....its connection is quite strange (unfortunately, I am not a very good technician, electronics). The input has a panel (pcb) that accepts... Read more

A lot has changed since the last version, so I thought it was time for a new thread. FXRoute has basically been rebuilt from the ground up. It now has its own fast DSP engine, runs headless on x86 and ARM, and integrates Spotify, TIDAL and Qobuz (unofficial). The goal is simple: powerful audio processing without turning the system into an IT project. The whole interface is web-based, mobile-friendly and designed to integrate the important functions in one place. Download &... ​ Read more

The software that implements the room EQ system is almost ready for release and you will be able to play with it. I am very interested to see if it does audibly deliver. Pierre Notes: You can find the latest version on GitHub and... Read more

The Dirac room correction suite is included - Dirac Live Room Correction, Bass... Read more
