Acoustic energy flying around the site of the tt. Put an acoustic screen around the tt, or better yet, move the tt to another room and I think you will see microphonics disappear.
What causes microphonics in a tonearm?
Several tonearms i'm considering have been accused of being susceptible for microphonics. The tonearms in question are the Pro-Ject(Oracle Paris-RPM 10.1)Rega(P9) and Rega based(OL) tonearms. Is the poor quality stock tonearm cable responsible or is this a design flaw? As always I appreciate your comments.
