Vibration Source?


Hello Goners. I haven't been able to find any discussions that address this topic, so here goes: As you go up the fidelity chain, in terms of resolution, do any of you encounter vibrations coming from the speakers that seem to be in the recordings themselves? I have a CD only system, and I detect vibrations in about one in ten or so CDs (usually old ones,) but only on certain tracks. The vibrations come from different speakers, depending on the track, but usually in the mid range. The vibrations on any given track sound to be tied to a specific instrument in every case. For example, in a clean electric guitar part, it's as if the vibration is coming from the guitar amp that was used to make the track, not from an issue with my speaker. However the problem pops up with piano and acoustic bass as well. If I put the same CD in my stock car system, it comes across as low level noise, not vibrations. But I rarely seem to encounter any low level white noise at home, only vibrations coming from specific instruments in a track.  Thanks for your insights.

That is a nice system with good resolution.
Could very well be anomalies in the recordings.
If you do get a small sample list together with time stamps some can check their own copies and see if it exists on the recording.  I've had a few GRP and Concord Jazz recordings with brief distortions in them.  
I just played Goodbye by Steve Earle. Listening to the bass, from my right speaker I’m hearing a odd harmonic distortion from the repeated plucked 1/4 notes.  Like a fuzzy articulation to the notes instead of a clean attack and decay. Seems like this indicates a recording anomaly.
