I have a HUGE difference on my subs when switching between 6ch input and regular digital input. The subs play much louder when using the digital input. I've tried setting all speakers to small and then setting all speakers to large. Did this on both the DVD player and on the AVR. I've also tried playing with PCM or not output from the DVD player. I can't get a combination that doesn't have about a 20dB delta. Makes it impossible to set the subs right. I listen to 6 ch for DVD-A/SACD and I prefer the digital connection for movies. My system is: Yamaha RXV3000, Denon 2200, VMPS RM2's, VMPS center, a pair of home built ACI subs w/PE 250w amps. Anyone else run into this or have ideas how to fix it?
