Only three manufacturers?

Great responses here and though I am a devoted Thiel fan and owner (CS6s), I also compose and record music in a home studio environment. I have asked Jim Thiel about this too: Hey folks, it matters not a rat's *ss if the production of the recording itself was MONITORED and MIXED on non-time coherent, non-phase coherent MONITORS. Just think, if the engineer is mixing and mastering so as to eliminate or reduce phase shift cancellations by ear, well if the speakers being used to actually do this don't have those features, then how the heck is the MUSIC ever gonna be time and phase correct IN THE RECORDING AND HENCE THE PLAYBACK up to the point of coming out of our speakers????

Jim/Shari/Kathy at Thiel couldn't even tell me studios they know that use phase and time coherent designs to PRODUCE music, so go figure.

My point here is that unless all music is recorded, monitored and mixed on phase and time coherent designs, then we will never benefit from what such designs can deliver.

It's just one of those situations in life that makes me think so much of our energy in listening and enjoyment just gets so bogged down in chit chat (even though it's fun once in a while!)

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.
