I have a Marantz M-CR612 with Monitor Audio Bronze 2 speakers and overall I'm very happy with the performance.

One little irritation with the system. Using the FM tuner, there's a 5+ second pause when changing stations, which I find unusual in a quality tuner. I have an older (5 yrs. approx) Marantz full-size hifi and the tuner changes stations with no delay.

Is a 5 sec. delay normal in receivers or could it be considered a fault as such?

It's an otherwise excellent system. I might add that I use the HEOS app as well as the tuner's remote control but the annoying 5 sec delay is there whichever way I change channels. Internet stations take a little less time to change (3-4 secs)
