Are we believers in leaving your equipment on 24/7 or not. The first time I tried this, three months in, the DAVE board died a death on me due to demise of cooling fan, this was preceeded by some exceptionally nice amplified static flowing around the speakers causing the amp to cut out. Any comments much appreciated. Burger. System comprises. A22+DAVE P35 DV27. Sunfire Sub. AE1 fronts. Monitor Audio centre and rears.
