I myself would pick up a little more head room and this one has a built in fan to stay running cooler.
The Hertz is 5 watts RMS if that in real life output of which you will not be able to tell by ear, but does provide Auto / Remote turn on wireless feature, is about all I can see the difference in the two.More headroom is what Id look for for your 80 rms speakers. I think looking at 60-65rms will be leaving you disappointed and wanting more power for your speakers to shine on the front stage and end up in the Clipping Zone
