Talk but not walk?


Hi Guys

This isn't meant to start a fight, but it is important to on lookers. As a qualifier, I have my own audio forum where we report on audio issues as we empirically test them. It helps us short cut on theories and developing methods of listening. We have a wide range of systems and they are all over the world adding their experiences to the mix. Some are engineers, some are artist and others are audiophiles both new and old. One question I am almost always asked while I am visiting other forums, from some of my members and also members of the forum I am visiting is, why do so many HEA hobbyist talk theory without any, or very limited, empirical testing or experience?

I have been around empirical testing labs since I was a kid, and one thing that is certain is, you can always tell if someone is talking without walking. Right now on this forum there are easily 20 threads going on where folks are talking theory and there is absolutely no doubt to any of us who have actually done the testing needed, that the guy talking has never done the actual empirical testing themselves. I've seen this happen with HEA reviewers and designers and a ton of hobbyist. My question is this, why?

You would think that this hobby would be about listening and experience, so why are there so many myths created and why, in this hobby in particular, do people claim they know something without ever experimenting or being part of a team of empirical science folks. It's not that hard to setup a real empirical testing ground, so why don't we see this happen?

I'm not asking for peoples credentials, and I'm not asking to be trolled, I'm simply asking why talk and not walk? In many ways HEA is on pause while the rest of audio innovation is moving forward. I'm also not asking you guys to defend HEA, we've all heard it been there done it. What I'm asking is a very simple question in a hobby that is suppose to be based on "doing", why fake it?

thanks, be polite

By the way there are a couple of very obvious reasons why some records (or CDs for that matter) sound better than others and there’s not too much you can do about it. Those two things are (1) Absolute Polarity and (2) overly aggressive dynamic range compression. For the former you can switch Polarity for each record and pick the one that sounds best. Or employ a Polarity switch. Otherwise, you get what you get. News flash! At least 50% of audiophile records are actually in inverted Polarity. Alas, even in Audioland there are no standards for Polarity. Who dropped the ball on that one?

For overly aggressive dynamic range compression, the only recourse one has really is to search out earlier issues of the recording that weren’t compressed as much. Otherwise you’re what they refer to as shirt out of luck. Of course, there are many other reasons why some records inherently sound better than others, e.g., they were made back when vacuum tubes were used in the tape recorders and mastering process, the engineers were superior, the recording venues were superior, etc.

No matter how much you wind up with in the END you would have had EVEN MORE if you had started out with MORE. - old audiophile axiom, the Law of Maximization 😢
I agree about the percentage of inverted polarity recordings.
With my latest upgrades, I can hear it almost all the time. And lucky have my polarity switch right at hand.
Sometimes it makes a big difference. Other times not much difference either way. Depends on the recording.
As for compression..
I was listening to Patti Smith CD "Horses' and laughed when as she was clearly singing louder and harder.. the volume level stayed exactly the same. Compression. (I should play the LP and compare?)
On the other hand, my speakers are still breaking in, and in Classical music, the softest have to be raised a bit , then the volume dropped to not blast at the climaxes.. 45dB range from pianissimo to   fortississimo on plenty of my Classical CDs.. And another 10dB down to silence. (If I sneeze next to the meter, I gain another 20dB over the top..)

The vinyl version of Horses is exactly the same fwiw.
I do not think I have played it again after my purchase
For the site, comparing different "Horses" issues..
Interesting the WORST DR are the 24/96 HD tracks !!!
