rlb61, Okay. I understand you are not interested in streaming and running an Ethernet connection to the 2nd floor is impossible. Please note that using an Ethernet over power connection works fine for your application. This technology sends the Ethernet signal using your electrical power lines using a small box connected at each end (source end and the router end).
For example, see the NETGEAR PowerLINE 1000 Mbps, 1 Gigabit Port with Pass-Through, Extra Outlet (PLP1000-100PAS) below:

Once you finish ripping your existing CD's to your hard drive, what are you going to play them on? I am not familiar with this the Sony Hap-Z1ES you mentioned above. I believe (please confirm) that you can copy your ripped CD's to the Sony and play them. My guess is the Sony will run without an Internet connection but I do not know.
I recommend you rip your files using an uncompressed format such as the Audio Interchange File Format (AIFF). It is an audio file format standard used for storing sound data for personal computers and other electronic audio devices. The Free lossless Audio Codec (FLAC) is another audio coding for lossless compression of digital audio.
