Can you explain the details of this 'contamination'? If the water is
described as 'distilled' I'd expect it to be free from any precipitates. Or
are you saying that the sellers are selling water that has *not* been
distilled as 'distilled'?...


Whether High Frequencies are lost when wet-playing is a moot point. *I*
wouldn't wet-play, as mentioned - but it could be that the lack/
lowering of surface noise gives *the impression* of less HF - similar to
hiss on FM stereo appearing to 'brighten' the sound...although I can see
the argument that water could 'smooth-over'/'fill-in' fine groove
detail..


I can see that a change in the noise may affect the impression of the HF
level, but I am unclear how the liquid would otherwise affect HF unless the
stylus is aquaplaning... The contact pressures and accellerations for HF
replay are very high. I've not seen any evidence that 'wet' playing affects
this, so I'd be interested in any.

Slainte,

Jim
