Installed in a Transport Pi Digi that sits on top of an Isolator Pi III with the Pure PI PSU. RPi 3 running Gentoo Player and Diretta.
Adding the SC Pure clocks significantly improves all areas. I most noticed vocals, it removes that digital taint.
When I first got my Sennheiser 800S I really didn't enjoy them. After 'fixing' the digital transport I love them.
