On your second question, that is not an unusual occurrence. Cross talk between inputs is common, even among some pricier components (I used to hear it on my Jadis JPL line stage). Way to fix that, of course, is to turn off the component that you're not listening to.
FM frequencies cut out by CD player
How can these two phenomenon be related?
When I am listening to my Etude tuner and then turn on my Rega CD player, the stations from about 98.1 or so will be cut out completely, as if you are flipping a switch on a tape monitor. The lower frequencies become somewhat fuzzy but still come through. Both components are feeding into an Audible Illusions pre-amp. Also, when the pre-amp is switched to the CD while the tuner is on and you are between discs, you can very faintly hear the music from the tuner through the speakers.
Has anyone else ever heard anything like this? Any ideas??? (The cd player is mounted on a shelf about eight inches above the tuner and the pre-amp is about eight inches below the tuner.)
