Mine is 99% through the Sonos network as follows............
FLAC for all CDs/Downloads from a Vortexbox software based system and Internet Radio approx. 95%.
CD's which are played through my Linn Classik, and listened to either in the study or output via it pre-out to Sonos input and broadcast.... at least until it's ripped approx 2%.
Pure DAB/FM or Ipod when either gardening, in the greenhouse, reading or doing DIY approx 3%.
I still have loads of records to RIP, but my NAD 533 has not been touched for over three years (easy) since the 'addiction' to streaming. All my cassettes are in the loft since being ripped - no player now. I have kept a Panasonic portable CD player to plug into the Sonos should the Linn CD player fail, however, when I can get all the artists that I like in FLAC as a 16bit/48khz download (don't need or can't hear HD sound quality), then I expect to 99% streaming, with a small fraction on portable radio or Ipod.
That's progress for you...... sometimes I even yearn for the purchase, take out of sleeve, put on, listen and read sleeve process........ but Sonos is just soooooo much more convenient, faster and fun.
