    Hi Jaap,

    Thanks for another interesting review. Inspired by your video tutorial on building your own amplifier, I bought the Soundimport purifi eval6 kit and it sounds great. More recently I bought directly from Purifi audio the luxery front end for the 1ET6525SA Amplifier Modules and that was a clear step up in sound quality.
    In short, you reviewed the original 1ET400sa modules, but in the meantime Purifi – like Hypex – has made interesting steps forwards. Maybe time to revisit them, e.g. the Eval 9 stereo or Eval 10 mono amp kits?

    Best regards,
    MarcelB
