I did have the fronts set to large, and yes, I do have a subwoofer.
During my search of prior posts this small/large thing came up so I checked and reset them to small.
I havnt tested since, was waiting til I got finished with the new banana plugs.
I also found little fingers had unscrewed one of the surround sound speaker cables from their posts
A little history to shed light on the possibility of lack of pwer :
I
used to be able to run this LOUD (at reference level) and just wondered what had changed to make this start cutting out at such a reduced volume.
I'lll finish up the banana plugs and test drive it this afternoon.
Thanks for the help so far!
PS ... The new Denon 3806 looks sooo inviting as an upgrade if power does turn out to be an issue.
