Nearly all manufacturers do not advertise/exhibit their product measurements? Why?

@kota1 

@amir_asr , you raise an interesting point about risk. As you are a dealer I respect the fact you might not like when a manufacturer or dealer assumes all the risk in a transaction by offering a 30 or 60 day return policy.

Once more, they don't assume all risks.  You have to pay for return shipping and hassle of boxing and shipping it back to them.  Then you sit there waiting for a refund which may or may not come.  And that burn-in period requirement is a sure way to make sure you don't immediately send the thing back.

You are a perfect victim of their marketing if you fall for this scheme.  Here is the wiki for you: 

"The use of money back guarantees has grown significantly over the last few years and has become standard practice in direct marketing across all media. Very often, unreliable businesses use it as a tactic to reel the customer into a false sense of safety....Issues relating to false guarantees have become so common in the United States that the Federal Trade Commission has specifically addressed the issue in the Code of Federal Regulations Handbook (§ 239.1)."

I suggest not being such a gullible consumer.  It is folks like you who let these companies get away with empty and false claims for their products.  Instead of being an advocate of audiophile buyers, you have joined the sellers in promoting junk audio products with zero benefit to fidelity of your system.

@dustyb13 That’s is the opposite to @prof posted on the rebuttal site. He is arguing with other ASR members that listening isn’t meaningless despite measurement results. He is using/preferring an inferior measuring CJ pre-amp instead of a very superior measuring Benchmark pre-amp.

@millercarbon I have in wall activated carbon filtering paneling which effectively removed excess bass nodes in the room. It was designed for six 12" woofers in my current speakers (or future speakers). Excess and uneven bass response is never a problem in my room Slight corner treble echo/reverb is as well as coherence/focus that a simple cloth in a narrow strip on the front wall cures (pending a more aesthetically pleasing panel or covering). When you walk into my room, it is unlike an anechoic chamber but rather quiet and calm. Once voice/music is heard, it is evenly transmitted and a touch on the live side, like a good performance hall. All of those absorption panels on the side walls and ceiling were designed to dampen the reflectivity of the cherry plywood finish. After reading Amir’s comments on Mike Lavigne’s room, maybe my room does "sound" better.

@fleschler 

Amir is so full of it... I tried six digital cables and they all sounded very different. Not just to me, but to five other listeners, two golden ear friends. My wife who is not an audiophile but has a very keen sense of sound gave me her comments.

People who believe in the results of everything from homeopathy, to new age healing crystals, to...name your unscientific belief...give anecdotes just like yours for their beliefs.

Some people just don't know what they don't know, and refuse to learn...and that's how we get a world suffuse with wild belief systems.

Again, as you can see if you read Amir carefully, while he has a good technical basis for being skeptical of some of the claims being made here, the door is not completely shut on any of your claims, or anyone else's.  It's just that he's looking for better, stronger evidence than yet another audiophile saying "My friends and I heard a difference!"  And quite rightly so!  Everything from green pens on CDs, little brass bowls placed on walls, stickers and pebbles placed on components, have had such testimony!

Until you grasp the relevance of listener bias and it's influence on our perception, your continued use of anecdotes to support technically dubious claims will continue to miss the point.

So @amir_asr feel better? Wow that took a lot for you. Did you take a nap? So you are making assumptions based on what you are reading on the internet and you do not know a single thing about me.

You did what you accused me of. Where is the science ?

Now what I do know about you is you have never posted your system or listening room. You have never posted the so called measurements for your room and system. Well not here anyway and I will not go on your site to help you secure donations from your minions.

I also know you are not an EE all you are is some guy with some software (that a member had to teach you how to use) and then you banished him from ASR. Yes that guy was over here saying all kinds of nice stuff about you and your lack of credentials.

So here we are back to that Elixir Salesmen (not the great Heed Integrated). That is you, a wagon peddler and the internet is your wagon and you con people to contribute to you.

When I bought my many systems I consulted professionals that came and measured (I am not anti measurements just anti shills and con men) setup gear and we did demos. We found what SOUNDED right in my home and that there was synergy in all the components across the entire chain, Acoustic treatments, cables, power, sources and amplification. Do you offer that type of service or do you just sell online? Would love to hear of some of your success stories from clients.

See when I am out of my element I do not throw cash at a problem I hire experts and get solutions. I may seek feedback form places like WBF and Agon but that is just part of my process.

I look at your expertise like those guys who claim to have served in the military, you know stolen valor.

You are not an expert, scientist, engineer or a respected reviewer. All my opinion. 

Please have a great evening and go play with your dog.

Why is it that people who have least amount of familiarity with audio science the ones that judge others to not have any such knowledge?  If I asked you how many research papers you have read the answer would be close to zero, right? If I asked you if you have any professional experience in audio, the answer would be zero, right?  If I asked you if you have ever had a mentor who knows audio science, the answer would be zero, right?

Why do you do this?  I answer: because audio science doesn't agree with what you have taught yourself from random individuals online, or improperly conducted listening test evaluations.  Show some emotional maturity in this regard.  Most of equipment I test at ASR forum come from members.  Out of the entire set of what I test, I only recommend about 1/3 of it.  The rest just don't perform.  Yet the people who send them to me are still happy to have done so and like the fact that they finally have some reliable data about their gear.  The move on with optimizing their system that way and routinely wind up with more performance at much less cost.

@amir_asr You are so full of crap!

Many retailers in this channel offer 60 and 90 day returns. No questions asked. Guess your business doesn't have the financial resources to put their money where their mouth is.

Just a few: Upscale, Music Direct, Audio Advisor, and on and on.

Cant run with the big dogs stay on the porch. 

Think we just have a False Profit in you.
