Is there anyone that has use this 3D adapter kit, How good or bad do this adapter do ?

Good points John.  For me it sort of helps to answer my question but for different reasons. That is: in those instances where i have a fully DDD recording on LP, the CD will probably serve me just as well.  I will note that many early CDs sounded bad because they were made from compressed-for-lp slave copies of master tapes or (in the case of some “twofers” (2 albums on one disc) a smaller size file was used to squeeze all the info on a single disc (zappa’s overnight sensation/apostrophe disc was way tinny sounding and fared much better—after complaints—breaking them out into two discs at fuller CD resolution

Regqrding the sound of vinyl vs CD and distortion “hidden” in the LP, more times than not I was amazed to find out that distortion I heard on vinyl—and which I attributed to my less than perfect condition pressings—were actually on the original recording. I was surprised hearing certain records by Zappa, The Velvet Underground, Dylan, The Moody Blues and others on CD for the first time and discovering that my LPs didnt sound so bad after all ... it was the way the recordings were made!

I do believe that analog masters contain more sonic info than 44.1/16-bit clones would be able to capture.  But I have to assume (unless someone explains otherwise) that for recordings made natively in the digital domain, then those recordings are what they are…. they’ll never be anything more than what the original was recorded at.

So there is probably no good reason to keep a digitally recorded LP if I can get it on CD these days… unless of course it contains a mix that was later changed/remixed

Hi Mark,

This has been my life’s work since about 1978.  We had some of the first digital multitrack recorders that 3M ever built, and a huge part of my life was supervising the cutting of analog (and later digital) tape masters into vinyl, following those lacquers through electroplating, and then the actual pressing into vinyl.  We had our own pressing plant, so I got to see it all happen every day, from trombonists coming through the front door to record jacket fabrication and excess vinyl re-grinding to make audiophile records.

The bigger point is not which sounds “better”—it’s what sounds most like what the mixer heard when he was working on it in the control room.  If you had the privilege, as I did for years, of sitting beside a mixer listening to control room monitors and watching as he went for a particular “sound”, often worrying himself about the accuracy of the speakers and the room acoustics, you would understand that the whole goal was to try to replicate what he heard. 

Analog tape was very good at that, but always lost a bit of transients, and increased the noise floor a bit, simply because of the limitations of tape.  Indeed it was often quite difficult to tell whether you were listening to the console output or the one-second-delayed playback head of the 2-track master.

When digital mastering came on the scene, first on videotape (we used black and white U-matics, which is why the weird sample rate of 44,100 came to be—it’s a multiple of the horizontal sync frequency of black and white videotape) we were all amazed at the transparency.  What we heard coming back from the digital deck was an identical sonic clone to the console itself, indeed showing the limitations of the console electronics.

Many consumers, however, had grown accustomed to the tracking and tracing errors and distortions that vinyl records inherently have.  No vinyl record truly sounded like what we were hearing on the mix console; it was several layers of distortion removed, with the distortions coming from the cutting angle of the cutterhead, the “de-horning” process which cut off the bottom of the grooves so that the vinyl would release from the stamper, and the inherent noise of the vinyl medum itself.

A CD is a much, much closer replica of what the original mixer heard on his board than an LP could ever be.  Now does that mean that you would rather experience what the mixer heard or experience what an LP listener of the era heard?  That’s actually a very serious question.  Almost no one who didn’t work in recording studios heard “clean” audio, and it was a very foreign sound to consumers, resulting in a lot of reluctance to accept digital media.  Consumers simply didn’t understand that they were, for the first time, hearing what we had heard in the production control rooms.  In many cases, the noise floor and distortion of the vinyl helped to cover up the limitations of the original master—making the CD sound “worse”.

I hope this helps, but I fear it may only add to the confusion.

NW. I bet a tactile transducer connected straight to the desk couldn’t even do that.
