Hi. I have a powering off problem with my Vincent sp 996 amps. Amps are connected to a Sony 840 QS integrated via pre out terminals. I have a pair of Kef Q1:s, which are driven in biwred mode by Vincents. The problem is Vincents to shut down on low level signals in few minutes. If i run a multichannel dvd, and main channels are on low level for sometime, power amps shut down. I also run a Dali swa12 sub via Sony sub pre out, and the autostart/off works fine with Sony. Any suggestions?
