DrWho Posted October 14, 2004 Share Posted October 14, 2004 For what it's worth, I too have used materials to reduce the vibration of my CD player and have had only good results; though the best part of my mods was that the CD no longer skipped during bass heavy passages. My intent for disccusing any of this was to find a technical reason for reducing vibrations...not to argue if it sounds better as that is a subjective test. I really don't think jitter is the issue and I think most of the music industry doesn't understand what jitter actually is or how it comes about. If jitter was the issue, then you should also notice the existence of jitter when using the digital output on your cd player; which is something I'm yet to hear. As far as vibrating tubes sounding worse than stable tubes...I don't have enough experience with tubes to have experienced such an issue. However, I am sure there are REASONS for the different sounds that you get. Quote Link to comment Share on other sites More sharing options...

lynnm Posted October 14, 2004 Share Posted October 14, 2004 LOL I find Celine Dion frustrating because she does have a great voice but rarely sings anything below a shriek. I had the same problem with Arthur Fiedler when he led the Boston Pops.....everything at full throttle pretty much all the time! Quote Link to comment Share on other sites More sharing options...

Yes, you are correct, the perceived degree of sonic degradation is subjective, but that still does not dismiss the reality that it exists.

Analogman ---------------- Well then, how exactly does "PIEZOELECTRIC MECHANICAL VIBRATION" alter the signal path? To me, it's just a random term thrown out there.

ben. Posted October 14, 2004 Share Posted October 14, 2004 Piezoelectric refers to the process of converting vibration to electricity. Surely you you knew that. What effect do you suppose external vibrational disturbances would have upon a system that derives timing for a digital clock from a microscopically vibrating quartz crystal?

Now it sounds like the vibrations are too big Quote Link to comment Share on other sites More sharing options...

I will admit that I'm not really all that knowledgable about this specifically, but logical conclusions can be drawn. Physics is physics.
