Only three manufacturers?

Bigtee, no argument, your points are well delivered and taken and agree with you from the premise that we must do no more harm than is already done. And that is particularly why I most often find myself playing vinyl from recordings that were kept in the AAA domain. I think it would be great if there were such a label that recorded, monitored and mixed with T&P accurate equipment just so that we would be able to hear once and for all, if keeping things strictly in this mode provides the resolution and accuracy we seek.

It sure would be nice. I wanted to add one last thing. Back a few years ago, B&W did do a recording that corrected time and phase and played it back over their speakers for a blind test to see if it mattered. When the results were tabulated, it was shown, that without fail, that the corrected version was detected almost 100% and was listed as the better recording. Makes you think.

They are right, but are missing some manufacturers. Add Green Mountain Audio. Also Dunlavy, but they are sadly out of business. The audio perfecionist journal will tell you a lot about this topic. A lot that many manufacturers don't want you to hear.
