I believe that I've hooked up everything correctly because I have no problem getting audio (or video for that matter). But whenever I turn on my system, I hear a loud pop which I never used to hear before hooking up the amp. Although the pop is not very loud, I'm worried that over time it may damage the B&W speakers. I've tried disconnecting the trigger but that did not resolve the problem. But when I turn down the input controls at the back of the amp, the pop is not as loud anymore. But I feel that by turning down the input controls, I'm also not using the full potential of the amp.
Does anyone have any suggestions for how I could eliminate the popping sound I am hearing? Do I need to ditch the B&K amp and try a different amp. The Emotiva XPA-5 appears to be on sale right now and I could try one for 30 days to see if it makes a difference.
Thanks for your help.

The older B&K's are still very good amps by today's standards, and have been known to be more likely to "pop" at startup do to the sensitivity of the line-in circuit when used with newer receivers. Before you move to a new amp, you might want to try an autosensing power strip first. Here's one that a number have used with success in eliminating the pop, http://www.amazon.com/Smart-Energy-S...ef=pd_sim_hi_1. I use one with my older Carver amp that doesn't have a remote trigger, and it works flawlessly!
