Chris, Fons, ok, this could be an issue. A while back I mentioned that I never build usable audio circuits on a stripboard, while the same circuits were usable on etched circuit boards. The route of short conducting paths and especially grounding paths already could make a difference. Cable length here usually is between 1.5 m and 3.0 m. Maybe it makes a difference were connecting "-" to ground. I'm still sceptic, that it does cause the issues for the Focusrite. It at least seems not to be impossible. The problem is, that nothing in the user manual gives a hint, to avoid plugging in TS jacks into the balanced outputs. Regards, Ralf PS: When I worked for Brauner, I soldered some of the Klaus Heyne Edition, my claim is that all Klaus Heyne changes are fraud. Reminds me of freeze-dried, neutral point earthing, peas and power strips http://www.vovox.com/en/home-audio-hifi/products/power-supply/ "Yes, power cords too, have an influence on sound quality. This is hard to believe and even harder to explain. But it nevertheless cannot be denied, once you have tried it. Often it is precisely this cable that transforms a good audio chain into a peak unit . A truly rewarding way to perfect high-end systems." - http://www.vovox.com/en/home-audio-hifi/products/power-supply/textura-power/ https://www.thomann.de/gb/vovox_initio_power_100.htm https://www.thomann.de/gb/glockenklang_high_end_powercable.htm?ref=prod_rel_251684_2 _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
