We tried that. Unfortunately, there was a perception among the gullible that snake oil was not to be called such, but treated with the same dignity and respect as real technology. So... no more snake oil section.

Interesting. This "wobble" (eccentricity accross imbalance) I have sometimes note. Especially if there are a slightly refused motor shaft bearing from the disc motor; then such discs dosn't play without dropouts.
In case of "Blu Ray" RPM's turns the player to an UFO in such cases - so I think.

Degaussing should be magnetic .......isn't it ? You must be refering to the antistatic gun ?

Just throwing this out there.... have any of you ever actaully done a comparison between a treated and non-treated disc (or know of someone you trust you did one)?



We don't want automatically closed minds, even if it looks like bullsh1t and smells like bullsh1t...... well it might be audio grade bullsh1t!!!


The reason I ask is that I have various lathes here and it would be easy enough to replicate what the machine does. Does anyone know the angle of the bevel it uses?

45 degrees

But it may be 135 degrees

as there is a difference.

I'm not here to defend these products, but...

Three things in my limited experience.

- a standard "heavy duty" tape demag unit seems to often have some sort of effect upon the playback.
- a subjective comparison here between two identical model and mfr "decks" running only as a transport easily shows audible "differences" between them
- the subjective quality of CD playback seems to vary all over the map due to things like SPDIF cables, power cables, transports, DACs, etc...

The "bits is bits" idea is fine, but out in the real world it seems to rarely work out that way...

Again, I am not posting in support of these products, just mentioning that apparently there are variables in "digital playback" that cause listeners to report audible differences.

They said 36 degrees "was the sweet spot", I don't know from what axis but presume the shallow one. I'm not sure if you need to do it pre or post cryo .

So is the bevel on the top (label) side or bottom?

And what sort of surface does the machine leave? Is it ground or polished?
