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

My car, really most any stock car audio system, helps make all kinds of poor recordings sound decent. My car is not tuned to these poor classic rock recordings etc... No, the fact is there is a sameness that a stock car audio system impacts on all recordings so they all sound decent. Is this fidelity to the actual recording? No. Far from it.

What are we after with our home audio systems? Homogenized sound that allows us to play objectively poor recordings well? Perhaps or perhaps not?
I also want to know more about “freeing” the capacitor? You can’t mean allowing it to vibrate freely? Next to other caps and parts that are loose and perhaps leading to a short? I find well damped caps sound better, not worse? 

I get the wood blocks under gear.  I get the room treatments, but they will never be allowed in my living room nor many others here.  

So take the cover off? Yes, I have found my old tube preamp sounded better that way. It depends on the component and not universal.  

The tube amp referred to is not point to point wired and all the components are certainly affixed pretty darn tightly to those boards. I much prefer point to point wired tube amps sonically. I looked at internal pics. If one does not glue, or bolt, or clamp a part it is not only vibrating with the music it is potentially dangerous in a high voltage amplifier. The best sounding capacitors are made highly damped such as the Duelund CAST caps. How these realities all work together is most interesting. Removing crossover parts from the bombastic bass cavity of a speaker and placing them outboard does improve the sound. This I have also walked the talk on with experience. Why do they sound better outside the speaker cavity? Two main reasons. You correctly state one now has the room to properly space all the parts - particularly inductors. Also, the parts are no longer vibrating, but are now isolated from the cabinet.
I find MG to be a breath of fresh air and a true innovator in a stale industry. I wish this thread did not get derailed. To bad for folks like me who are open to what he has to say. I like hearing views that stretch me. Really sad. Years ago this site was not like this, at least not to this extent. Such a shame.
@uberwaltz.  I was not referring to you really. A little bit of healthy skepticism coupled with your humor is just fine. I grow weary of the long and repetitive argumentative posts from folks who really just need to move on as they will never enjoy this thread.  That’s fine if they can’t learn or agree with MG and others here. However, why continue to derail the thread and waste our precious time as some of us would like to expand our knowledge here. Constantly trying to put a negative spin on someone’s motive and methods is just not what these threads are meant for. Today it seems many think it is exactly what these forums are for. 
@prof
I do not share your perspective. How we all interpret comments and actions is always based on the lens or perspective we view those comments and actions through. If you’re looking for offense you’re going to find it is certainly true in relationships and even here in threads. The lens or perspective you’re using is yours and differs from mine. I don’t see the offenses you see. Time for you to perhaps let this thread breath and have some real value for the rest of us.

Our perspectives are really choices. I have decided to view people and all manner of life situations and events through a lens that I sense is becoming rare in today’s communications and community. A lens colored with shades of intentional curiosity and peacemaking.  No reason for me to look for offenses between the lines as most times they are not real or healthy to dwell on.  
I will add that you seem like a very smart man and one I could learn from.  I honestly view MGs comments and motivation as helpful, fresh and born out of a healthy dose of curiosity. 
I just read these posts and my system still sounds the same? Learned nothing. Perhaps my system sounds worse as my emotional state is not at peace. I guess I’m also out of this thread and one of the weaklings who can’t take the heat. I leave pointing out the fact that the forums here on Audiogon are losing more and more good Agoners who are weary of what this site has become. A lot of good ones are now gone or have decided to stay mostly quiet.

MG is indeed a breath of fresh air and is onto something we could all learn from. The confrontational posts continue to derail any hopes of this and others threads ever amounting to anything of real value. Not every subject matter and thread is about debate and arguing. Can we hear about what tuning measures, devices, stands, platforms, modifications, gear etc.., was used to bring about such engaging music?

@mapman 

I just realized you have over 15,000 posts! Oh my goodness you deserve the trophy!  
Because it keeps getting sidetracked. At least that seems like the obvious and clear answer. This is not to say the off topic posts are completely without merit.  It simply states why the thread is not marching forward with useful tuning information. I define off topic as the picking apart of words and statements looking for perceived ill motives and ammunition to call into question the character of posters.
I am not taking the bait. I just want this thread to be something useful not an ongoing grey matter bantering competition. Prof, you may be right that this thread will never get there. I think the OP intended to get there, but it won’t happen it seems. I like reading your other posts on speakers etc...we just see this one far differently. Let’s enjoy some music and agree that music and audio is one of life’s pleasure. 
Can you please tell us how the Pioneer amp went from rags to riches? I must admit I am almost out of patience with all the vague posts with no specifics.  What mods were done to it...specifically?  If we cannot get any real answers, then I will also need to move on as tuning seems to be all talk with vague and invisible walk. 
My Lyngdorf 2170 sounds better with the top off.  I also noticed this years ago when removing the top off of my TRL Dude tube preamp. The builder suggested I try it. He was right as it simply sounded better. More open and relaxed.  Sure, I know it sound nuts. 
My system is posted on Tuneland. I genuinely wanted to learn more about this tuning thing. Thus far all I have learned is that Tuneland is a very sleepy place and no ideas or help thus far. Heck, I tried to purchase some tone-wood footers and could not even get that done. Seems little talk and no walk. Not impressed. I am most open minded and like to learn how others obtain great sound. Seems Tuneland has nothing to offer but vague language and strangly cluttered listening spaces.


Agreed in that no way many could have rooms as shown on Tuneland. I did post on Tuneland that I could not add all those platforms and wood pieces around my room. That may be why I am not getting any help there.  Those are pretty strange looking spaces that will not accommodate others in the same space.  I bet the rooms and music sounds very good.  
No, one cannot know exactly how a system sounds from a picture. Well, they can actually get a fair idea sometimes. If I see a big TV screen in between the speakers on the same plane , then I know what that does for sound. Same for many speaker placement errors. I used wood platforms and assorted wood diffusion and footers over the years and have a sense for what they do for sound also. So based on my many rigs, set ups and experience I can certainly speculate on many SQ attributes from pictures.

That being said, the Tuneland rooms are extreme and while interesting to me, they will always remain a curiosity as there is no way our living room could ever look like that!


Yes I am aware of dipoles and how they interact. Been there, done that. @trelja is spot on.   I just feel typing every sonic attribute I am aware of with various pieces of gear and how they interact with rooms would have been far too long a post. Yes, a picture can tell part, not all, of the story in SOME cases. 
I would like to buy some closer to $50 each, not $90.  Wish they had a sale.  Two for one deal and I’m all in.  
Seems Geof is spot on regarding wire directionality....

“Directionality in Cables

It’s all about grain structure! The microstructure of copper and silver conductors is actually made up of individual grains of the metal. Unavoidable angular patterns in this grain structure can cause cables to perform differently in both directions. Wireworld cables are manufactured utilizing a proprietary Grain Optimization™ process that specifically controls the grain structure of the metal to produce the highest fidelity when the signal flows in the direction of the arrows printed on the cable. Some other brands of audio interconnects are directional because their shields are only connected at one end of the cable. The shields in Wireworld cables are connected at both ends to provide superior isolation from noise.

For peak performance, always install Wireworld cables with the arrows pointing in the direction of the signal flow.”




I sure miss my Soundlab M1 speakers. They were spooky real and so natural sounding. Very special speakers and I have owned many. I have to say they are at the very top of my list. So musical and meaty. However, thry just take over a room aesthetically. That is the only downside I can think of. I lost my dedicated room and just no way these will ever be in our living room.

I will never forget the wonderful music they produced.
