HDMI over Analog or other connections

Hi Folks, I have recently purchased a Sony XA5400ES CDP and will connect to a Cambridge 840E pre amp. My question is what connection will provide highest 2 channel audio quality? HDMI, RCA, XLR, Optical Out, Coaxia Digital..?

Inputs: 8 pairs gold plated RCA stereo phono inputs

Audio Outputs: 2 pairs gold plated RCA stereo phono outputs 1 pair XLR balanced outputs

Dont see anything about HDMI....
IF you actually had a receiver that came with HDMI inputs.. Then it would depend on the quality of the decoders. The biggest reason to use HDMI is ease. One wire instead of up to eight separate wires.
