Def CD. My wife, occasionally, actually pays attention to what I’m playing. I was listening to my newly received Japanese recorded CD of Days of Future Passed when, from the bedroom around the corner, I heard “wow, that was so clear . . it sounded great.” She did have a basis of comparison as every morning for about 3 weeks before it was DOFP on Spotify streamed through a Mac MB50 to a Mac MA252 to SF Olympica llls. And for me sitting in the sweet spot, the richness and timbre of voices were definitely clearer and fuller on the CD. But, Spotify has given me a universe of music for 10/month. Best of both worlds. And my CD player is a Sony 300 disc changer. Makes me sad to think how much better the CD might sound with a “real” CD player.
