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

"But.... instead of modifying the power supply to be more indifferent to the characteristics of your own mains power, we’re here talking about running mains power through undersized wire gauges? I can’t possibly be the only one who sees the inverted logic of that reasoning."

I’m glad you made the post you did. It was helpful to see where you are at in the hobby.

If you look at most amp designs today they operate much cooler than what you are describing your amp runs. You should look into this to see if your designing is up to par. If I was running my amp as hot as yours I wouldn’t want to have you using my wire either, or anyone’s wire. Last night I put my hand on every amplifier I have on at my place and I didn’t feel anything that was any more than warm, certainly not how you are describing your amp as a fire hazard. In fact all the amps I use have very low transformer heat output, I could easily keep my hand touching them all night.

Kosst, you started off your post "I’m no electrical engineer, but do I really need to point out the obvious?" That to me is what is fairly obvious, you are no engineer. That’s not me being mean that’s me being obvious.

Have you ever designed an amplifier from scratch kosst? Maybe you could find a designer to work with you until you are able to make a product that is not a fire hazard. At that point you could explore wire sizes and how they actually work.

Kosst

I hope you are ok with me taking the time to answer your posts today.

I have a couple of questions for you as well.

Do you know what makes a wire get hot?

Do you know why most codes in the US specify using 12 gauge (solid core) wiring through their houses?

Do you know why 24-20 gauge is the most common gauge for hookup wire?

Do you know why manufacturers choose PVC, Teflon and other materials as jackets on wires?

Have you ever done a heat testing on wires yourself?

To be as clear as I can what makes you think obvious when you have stated you have never been an EE, have you ever studied EE before?

You know saying someone has been selling fire hazards when there has never been even one case of this in over 40 years with anything I have ever been a part of is not only a joke, but makes you look like what you claim to be, an untrained inexperienced hobbyist who hasn’t figured out how to make an amplifier, yet, that runs cool.

At least the Audiogon forum is entertaining if nothing else, when folks come up to show off their knowledge or personal experiences. But when it’s time to put reality to the test there needs to be walking to go with the talking for folks to feel confident enough to engage.

The most important question I have for you Kosst is "are you a pawn or someone who can step up their game of experience past creating fire traps yourself"?

I’ve already done my UL course, why don’t you give it a try? Put a little walking with that talking, it gets boring hitting the Abuse button on the flagging option.

step up bro, be happy to converse with you in the real world

You may serve yourself a little better in some eyes by NOT admitting to flagging people’s posts consistently when they are at odds to your viewpoint or opinions etc.
I have yet to see one of Kosst posts that genuinely fit the description of abuse towards yourself.
Granted he can be very abrasive and not all of his input is absolutely accurate but you do yourself no favours in my eyes by bragging about flagging his posts.
Just my 3.7 cents worth.

@elizabeth why is it when someone brings up a questionable point about your posts you attack the poster instead of addressing the point?
