Hi All, I have experienced the following problem very occasionally for the last 2 years - today was the first time it's happened for about 6 months. When playing vinyl, the P85 suddenly shuts down and the A85 mutes displaying the message "DC OFFSET CHECK CONNECTIONS". After waiting a few seconds and powering back on, I can always play the same record at the same volume without problems. Relevant hardware is Michell GyroDec, Rega RB300 (re-wired with the Incognito kit), Sumiko Blue Point 2 MC cartridge into Musical Fidelity X-LPS phono stage into Arcam A85 and P85 bi-amping Mission 753s. I have checked all connections and used a multimeter to check continuity and there are no shorts anywhere from cartridge tags through to the Audioquest cables from the phono stage to the A85. Any ideas what could be causing this?
