Decreased volume with Blu-ray
This happened to me recently when I bought my new system. Pioneer elite 94 TXH receiver and BDP-05 player. I had to change the receiver settings and put all 7 speakers to smalll because I have a powered subwoofer. I addition you have to adjust the BD players audio output to bitstream. The volume control on my pioneer is about the same level as my previous Yamaha RXV 2500. They both are supposed to output 140 W/channel. My front speakers are POLK LSI 15's and need power. I have no complaints but I am still experimenting with the amp and BD player. Try this. I hope it works.
