I use one of those in the car, and it sounds like utter shit. I think it's the bandwidth limitations of the transmitter, but music sounds like it's in a fog when played through it. Overall playback level is very quiet, lows end is way disproportionately loud, high end is poorly defined...
It may be my particular model, but if you're expecting the sound you know and love, you wont get it.
I worked with engineer Matthew Ellard quite a bit back in the day, and he almost always brought a boom box with him to his sessions for the exact purpose that you describe. His box had a pair of RCA ins, and he had two tt to RCA cables, took a feed right from the patch bay.
If you're handy with a souldering iron, I'd think there should be an easy way to interrupt the CD player feed. But I'm not much of an Elec Engineer, so I can't speak to specific mods...
