It works mostly, but occasionally the audio will drop out for a moment. As I am using ABC A1 it kind of manifests itself as a very deep and slight thud emitted from the sub. I have been in touch with REL who seem reluctant to allow me to buy the part so I can fit it myself. It looks to be a simple soldering job and I don't really want to pay for the privilege of having my Strata shipped and repaired when I'm fairly sure I can do the job myself. Anyone have any advice? Perhaps another way around the slightly dodgy connection on the switch?
