Why are you blaming the amp? How do you know it was not the source?Update and advice needed.
Returned the 1600 just in case it was faulty, decided to go for the 3700 so big swing from my starting point.
Anyway appears this has a different fault - the audio cut out 3 times whilst watching a movie (for about a second each time, the movie was still playing fine).
So I’m going to return it but wondering whether I stick with the 3700 or go back to the 1600.
Reason is I didn’t really notice any difference in sound quality to justify the extra £620. In fact the base sounded worse then on the 1600.
Maybe my 7000i speakers simply aren’t good enough to go with such a good amp and in a weird way the 1600 might be better suited?
