CDP caused tinnitus?

You have several good points here.

I had considered that the dynamics may be different, possibly the high freq might accentuate it, or even the speakers were contributing.

One thing I was interested in is if it were possible the cdp creates any emphasis on higher order harmonics.

The effect is not subtle, it's got to the point that even through headphones plugged into the cdp I can only take a few minutes, even at quite low level listening.

I can't figure out why the TT rig lessens the effect to such a high degree.

Just curious if any others had noticed this at all.

Thanks for the ideas. I will try a different power source and see what happens. For the last few years I've had the cdp plugged into a BPI, I wonder if that could cause any problem here.

Thanks for the tip

Gerardff,

I also have the low freq motor hum. This one comes and goes and I haven't yet figured out the cause. Feels like around 70-100 hz maybe.

The issue I've most suffered is a high freq sound. I don't know the freq range, but seems like is more on the order of 6-8khz or like that. It becomes more intrusive during some music playback. It will then be more pronounced for a period of time then subside again.

I have time available in the next week and will be getting an overall health checkup. At that time I'll see if there may be a systemic cause or what.

Thanks to all for your well thought out replies.
