We definitely don’t know it all. In fact nothing could be further from the truth. If we knew it all we couldn’t learn anything from the piles and piles of records we listen to every day.
On practically every shootout we learn something new about our favorite records. That, more than anything else, is what makes the kind of tedious, time-consuming, mentally exhausting work we do fun.
The stuff we were wrong about, and there has been plenty, you can find right here on the blog, often under the heading Live and Learn.
It should be said that most audiophiles, at least the ones I know well, do not have the patience to critically analyze ten different copies of the same record for hours on end. For me (and everybody else who sits in the listening chair), it’s all in a day’s work.
I learned to critically listen for extended periods of time back in the early ’80s. I got heavily into — obsessed with might be more accurate — tweaking my table setup, system components, wires, vibration controlling devices and the like.
Listening for differences in interconnects and listening for differences in pressings calls upon precisely the same set of skills. If you can do it all day, if you actually like tweaking and analyzing the sound of your stereo for hours and hours, you will undoubtedly end up with a much better sounding system, as well as one helluva high quality collection of records (not to mention very finely honed listening skills).
Here’s a good way to chart your progress.
