Forget all the " problems " during LP playback I posted and think for a moment how you or any one could gives " support " or speak of " superiority " to the LP playback when in this medium we can't even READ WITH ACCURACY WITH PRECISION ANY SINGLE GROOVE IN ANY LP!!!!!!!!!!
Raul, this is blatantly false and if you actually believe that then you need to know its not true. Now, it is true that cartridges and arms have certain limits, some being better than others. Like I said before, its the mark of a good mastering engineer to understand those limits so he can produce an LP that can be played but still shows off the master recording (unless its directly to LP...).
Now I did comment directly to this issue of traceability above, but the *generalization* that no groove can be tracked by any cartridge is simply too much of a generalization. If that were true LPs would not still be around.
Again, you should spend some time around a mastering setup to see what the recording was like before it went into the grooves. Then listening to what the cartridge/arm combo thinks is there, sounds to me like you might be quite surprised at what is possible.
Its also helpful to make a recording and then put out an LP and a CD of it. That is perhaps the most telling. I have such recordings- one of the better known ones I have done is Canto General by Mikas Theodorakis (peotry by Pablo Neruda). Its pretty easy to discern that the CD **in no way** is able to keep up with the LP on a decent playback system.
I had a guy come into our room at THE Show this last January. He was somewhat notorious on the AudioAsylum.com website for his rants about phase and digital. He did not know that we had a phase switch on our preamp so he had us play a CD and then said that reversing the phase would make it better. I flipped the switch... so there was maybe a very small difference. Then he as insisting about how much better the digital was over analog if it was 'in-phase'... So I put on the LP for him, which instantly smoked the CD (we had a very nice digital system in that room BTW). So then he proclaimed that if there was an analog master tape involved that what he was talking about didn't apply. It was obviously a face-saving comment- he got up and left as fast as he could. I'm afraid we had a good chuckle at his expense.
Raul, I was pretty sure that you are making a phono stage and a tone arm. These comments of yours sound to me unlike what I would have expected- have you experienced a change of heart?
