@richardbrand The condition of the master tapes is an issue that anyone interested in digital has to face. In many cases, they’ve degraded a lot since the original LP was pressed. So the digital release won't be as good.
For this reason, if you are interested in really hearing how the music actually sounded, quite often you have to get the LP even if you are a digital maven.
LPs have considerably less distortion than most digital advocates realize. This is because any stereo mastering system has an enormous amount of feedback, more than most ’hifi’ amplifiers! My Westerex mastering system used 30dB, wrapped around the mastering amp which has feedback of its own.
99% of the ’distortion of the LP’ comes in during playback, due to poor tonearms, poor tonearm match with the cartridge complicance, poor setup and a poor platter pad (whose job it is to control resonance in the vinyl as its being played).
The real weakness of the LP is setup, not its actual fidelity.
I use a copy of ’Soular Energy’ by the Ray Brown Trio as demos at shows. Its an excellent recording in every way.
BTW, the phono preamp is a hidden offender in many cases when it comes to the major objection digital advocates raise: ticks and pops. If the phono section has poor high frequency overload margins and is susceptible to RFI, it can generate ticks and pops that sound like they are on the LP surface. This is a common problem! With LOMC cartridges, this problem has lead to the myth that the cartridge has to be ’loaded’ to sound right. So yes, this is a common problem.
If your phono section has properly dealt with this problem then you can often play LPs with no ticks or pops on the entire side. I’ve been doing that for years without any particular care of the LPs other than proper storage and a carbon fiber dust brush.
