I purchased a B&K AVR-307 first part of this year & had a TERRIBLE exp with it.This thing gave me fits from the start. First time it was hooked up, it sent a LOUD popping sound through all of my speakers each time I turned it off. I sent it back to B&K, Was told it had a wire crimp and that it was fixed. Second time I hooked it up, It did EXACTLY the same thing. I sent it back a second time. They said it had an additional problem they had missed the first time around and this time it was fixed correctly. I got it back, hooked it up a THIRD time and the popping was fixed, but now it would not let me access my higher number movie channels (HBO,Showtime,Etc) At this point, I was sick of the entire B&K adventure, So I returned it and swapped for a Denon AVR 5803. BEST move i've ever made! I suppose it's possible I just had very bad luck, But this has left a bad taste for all things B&K and I will not ever buy anything else with their name on it... Good Luck, and if you want to discuss this furthur e-mail me and i'll give you my phone number. Phil Griffin.
