People showing how great their turntables sound Reply #50 – 2010-10-14 11:59:42 Quote from: Arnold B. Krueger on 2010-10-14 11:42:25What I come up with, based on decades of experience trying to do such things, is that the odds of random influences actually compensating for some nonlienar distortion are pretty much slim and none. and mostly none Even when you know what you are doring and you are desperately trying, compensating for distortion by adding other distortion is a tricky business. This is particularly true for nonlinear distortion because nonlinear distortion has so many parameters that you have to hit square on.It's not so random though, is it?I mean, a recording is generally cleaner (in a lot of ways!) than a live event. Vinyl is generally less clean than a CD.Anyway, to make it better in a subjective sense, you don't have to reverse the mathematical effect of the change - you only have to make another change that brings the emotional response of the listener closer to what it would have been, and (for the practical purposes of listening to music), you've got closer to the original experience, even if in pure signal processing terms you could be even further off.Think of the tricks film makers use to create emotion in cinema - which make the (until recently) 2D 24fps presentation even more distorted from reality, but in a way that certain feelings and expressions are conveyed better through the limited medium available.I'm sure sound can and is manipulated in the same way.The only disagreement is probably that most of us think that manipulation should stop when it leaves the studio, while others are happy to let their playback equipment manipulate it a bit more!I have to be bluntly honest here and say that I have several thousands recordings on various formats, and I can't think of one where the audible or barely audible distortions of vinyl conclusively improve it without also degrading it in some way - the only positive examples I have are of recordings where the CD master is clearly inferior to the vinyl master for some reason which has nothing to do with format.But I do have plenty of recordings which I can intentionally change myself to sound better to me - and in some of those cases, I think the changes would generally be appreciated as an improvement by most listeners. So I don't agree with the general implied rule that a recording mustn't change after it leaves the studio.So I don't think it's beyond the realm of possibility that very subtle vinyl characteristics can improve some recordings - which is why I'd love to hear some examples.Cheers,David.
