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

Uh, Robert, we’ve already covered the dodgy subject of why low mass systems have advantages over, you could even say they’re superior to, high mass systems. Your friend and humble scribe laid out all the gory details the other day. Were you on holiday? Here it is again in compressed form. I am not trying to put words in Michael’s mouth, by the way. He almost certainly has his own words. These are my own observations with my own low mass system. Ooops, there’s that word again! Observations.

Low Mass System Advantages

No big honking 🦆 transformer or one that has been removed and relocated elsewhere.

No big capacitors that vibrate and shift the phase.

No large chassis that vibrates.

No fuse to worry about.

Minimizes internal wiring, about 50% of which is soldered in the wrong direction anyway. Plus there is simply LESS things to distort the signal or vibrate.

Lightweight components are easier to isolate from vibration.

Cost is much lower. You can spend more on tweaks or whatever. 😄

If the low mass system is battery powered (like mine) you get all the advantages of getting off the grid, eliminating ground issues and power cord issues, including RF coming in on the AC line. Also, no fuse, no transformer, no interconnects, no speaker cable. No more teacher’s dirty looks. 🤨

Oh, my. jf47t, I believe that is what's called having your a*s handed to you....

thecarpathian,


I was quoted on Tuneland for saying people here have been polite enough not to infiltrate Tuneland. They got named "cockroaches" although for cockroaches better word would probably be "infest". I warned Audiogon crowd would have a field day there and it is better that two sites stay divided. Well, the dam has broken and Tuneland is here now, for better or worse. If nothing else, it will increase the traffic at Tuneland which may be a fair trade-off.
"Also, no fuse, no transformer, no interconnects, no speaker cable."

Could a headphone cord be considered an interconnect or, more likely, a speaker cable?
