CDP caused tinnitus?

The CDP does not cause the tinnitus, it only helps to present the audible affects. Tinnitus is a ringing in the ear. Your CD player, and many are delivering frequencies that are instigating the affects of your ailment. It is likely that when the same music is played through your turntable, that these specific and likely higher frequencies are being rolled off and therefore not instigating the same inner ear affects. Tinnitus can be a sign of several different things, some of which can be very serious. I would consult initially with an audiologist and/or an ENT.

Arkprof, from a sufferer of tinnitus (as you have stated) it surprises me that you are making such a statement. My wife is an audiologist with 10 years of undergraduate and post graduate training and another 15 years of practice. The idea that tinnitus may be set-off by certain audible situations (one of which could certainly be music/sound related) is not unusually rare, though not necessarily common either. Unfortunately, many people who suffer from tinnitus may simply be less congnizant of the situations preceding specific occurances.

On another note, I cannot sleep with my watch on, as the noise of the watch (with my wrist underneath) my pillow keeps me awake. I cannot hear my watch through just air when it is more than 12" away from my ear. If I am driving down the road during the summer with my window open, I can hear the power lines hum/buzz (if the lines are running next to the road). When I mentioned this to my wife she said this was impossible, that the noise from the open window in the moving car would overpower the hum/buzz from the power lines. She later tested my hearing in the sound booth at her clinic. She stated that I could hear certain frequencies at volumes that were lower than what normal human hearing should be able to discern. Don't get me wrong, I certainly am not one of those golden eared people that can hear super subtle differences, such as changing some cables (I can hear differences in some cases, just not all) or the difference when cables are on stilts vs. just on the floor. Also, I cannot sing worth S*#T, to me it always sounds like I am perfectly on key - but everyone around tells me I am no where close!
