Unless I am misunderstanding what you are attempting to do, just split the CD player's left and right channel analog outputs to feed the stereo inputs of your two separate analog components. I'm assuming your "Yamaha DSP" is an integrated amp and the other unit is a receiver or another integrated amp--you are vague on this. It would've been helpful to provide the specific models.
Use these or something similar:
Music room: Cary SLI-80 tube integrated amplifier, McIntosh MA6500 integrated amplifier, Quad 99 preamp, Quad 909 power amp, Acoustic Research AR9 loudspeakers, Yamaha CD-N500 CD player, Teac UD-503 DSD DAC, Phase Linear 8000 II linear-tracking turntable.
Theater room: Panasonic 65S60 plasma television; Yamaha RX-A2020 (preamp section); Adcom GFA-5503 and GFA-5400 amplifiers; Polk LSi25, LSiC, and LSiF/X loudspeaker system; Velodyne FSR-18 servo-subwoofer.
