Question about streamer to "serve" 2 systems

I am 100% CDs guy now.... have dedicated stereo in my basement room but also a decent 5.1 system in my Living room but that's mostly for watching TV....
I want to finally try streaming....but the way I want to do it is as follows:
- Keep my main / critical listening to CDs but also be able to access my music from my other rooms / outdoor patio
The way I am thinking of doing it:
- Buy something like the Wadia M330 (see them used for ~ $1600) - set it up in my main system - connect via XLR to my preamp and use it for listening to internet radio / streaming / trying new artists on my main system while I am in my dedicated room.
- Run about 35 feet SPDIF (do they even sell them that long???) from the Wadia to my SONY ES received in the living room and just power it on remotely and then I'd have the ability to also listen to my music in the living room or outside (zone 2 speakers) if I just want some music playing in the background...

Is that do-able ?
Would Wadia M330 be a good choice for under $2000 or would your recommend something else?
If there are no 35 feet SPDIF cables...could I used ST-ST computer fiber channel cable or would I need to run something else ? I don't think it's good to run such long unbalanced interconnect (RCA).

thank you
