I’m late to the discussion but I am looking to hook up a Cambridge 851D to my HK990.
I contacted Harman Kardon and Cambridge Audio to find out if these components are compatible before purchasing the 851D. Still waiting for a response from HK but here is the response I received from Cambridge Audio…
"You can totally connect the Cambridge Audio Azur 851D to the Harman Kardon HK990. You can do that in several ways. You could use a digital input on the HK, but the best connection you have available would be to use the XLR output connectors on the back of the Cambridge into the HK XLR input. If you don’t have anything hooked to those on the HK you can expect some amazing sound with those hooked ups."
