You both make very good points. Prices are getting steep and the quality control isn’t there. I will note that vinyl isn’t my preferred medium as I have significantly more invested in my digital source, and more than I should in vinyl. But they can both be satisfying mediums and disappointing mediums at times. So, I’d prefer to not let this discuss devolve into what’s better.
The question I originally posed has been answered: not much noise is acceptable. It’s an imperfect medium but close to silent is achievable.
That said - as I noted earlier, even silence may not be the only goal. The Norah Jones album I purchased (and am returning as it had too many defects) also sounded poor. Why there are so many remasters of so many greats is bewildering. I am becoming ever more skeptical of anything with a “remastered” in its name.
