Are you certain that 'wow' isn't on the record?

Maybe he hasn't any Bow wow wow records

The cutting lathe has to
have just as consistent speed as the turntable. And then there is the
centring of the hole.

I;ve often wonder whether there;s much differnce between the makers pressing the vinyl from RCA to polydor or whoever.
I have some flexidiscs which are pretty crap, coloured & picture discs some 1980s that are thicker than the norm, then there's 12" imports and 7" and 10" EP I have a bat shaped 7' too.

I'm not convinced they are all of the same manufacting quality or material quality so I;'m not sure if there really is one quality for vinly and of course digital is MP3(various bit rates) ACC, wav, AIFF, FLAC, Apple lossless
etc...
