I suspect you should run them like burn in, I don’t think the denon receiver and your cable are the right one for the 805 ,silver are good for those speakers..clear day cables are silver affordable , to get the most out of it....get good receiver...
B&W 805 Nautilus for PC?
I picked up a used pair of 805 Nautilus at an estate sale for $500. I could not test them and had to take a gamble. My plan was to use them for my computer as I spend a lot of time working at my desk and wanted something better than my horrible Bose multimedia speakers. I am in search of a good integrated amp but in the meantime I am using an old Denon 1908 receiver to run them. They sound terrible. I am not sure if it is the Denon or the speakers. Is there a good integrated you would recommend that might make these things sing?
