As I said the problem is not in the phono stage ( I mean the main
problem. ) but the huge differences that exist in both proccess:
recording and play where digital is way way different to how things goes
with analog where almost all " thousands " of steps/stages where the
signal pass through degrades the signal and you can't argue nothing
about because are facts, no matter what. Example other that how the bass
is recorded in digital:
@rauliruegas This is one of those areas that because you are not in the recording industry, there are things that you don't know, and you don't know that you don't know them.
Here is an example: When a project is mastered for CD or other digital release, quite often it is compressed. This is because CDs are played in cars. When the same project is mastered to LP, the compression is less or non-existent. This is because there is no expectation that the LP will be played in a car. You can talk all you want about dynamic range, but the fact is the industry doesn't care and they want it to work in a car.
Several other points- the LP has since the late 1950s bandwidth well past 30KHz. Playback apparatus has had that ability since the late 1960s. Our (older) mastering electronics are bandwidth limited to 42KHz but could go much higher without the filter at the output of the mastering amps. Digital has never had this sort of bandwidth.
Actually the EQ used by the LP system works pretty well. If we record a 20-20KHz sweep tone, we can play it back with no variation (within 1/2db) on our playback system that we use for testing of cuts, which consists of an old Technics SL-1200 with a Grado Gold, running into a Harmon Kardon HK430 receiver made in the 1970s. Your remonstrations notwithstanding, LP EQ is far more accurate than you make out; the real devil in the details is actually the master recording itself and how much EQ was applied to that before we ever see it.
So 'Nah' is simply 'what is'; right now the digital isn't out there to do the job. I have hopes that it will be and by all indications it is still improving. But you have to wonder why in the heck vinyl is so much easier to find these days (1992 was the year of least vinyl production, over a quarter of a century ago); if it isn't obvious, it is that as a prior art, the succeeding art failed to be better and the market knows it. That simple fact is really all anyone needs to know about this.
