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

@jerryg123 

I am a dog guy @amir_asr just not a one to listen to shills, and liars that hide behind alleged science.

So sad and pathetic.

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 , I did the "blind test" as you posted, that’s it. The $250 is refundable, no risk:

Folks sell ointments online to grow hair with money back guarantee.  That doesn't mean I am going to go and buy them to try and I hope you are not either.  They are hoping that you procrastinate and get stuck with the thing whether it performs or not.  It is the oldest trick in the book for mail order/online selling.  

And it is not free either.  You are not only responsible for return shipping, you must also insure it and go through the hassle of boxing and sending it back.  On top of that, they could complain about it not getting to them, being damaged, etc.:

" We strongly encourage customers to send product returns using a shipping method that is both trackable and fully insured.   It is your responsibility to ensure the returned item arrives to us undamaged.  Mapleshade will not accept responsibility for returned items that are lost or damaged during shipping.  Once received, we will process your return promptly.  Then we will issue your refund or credit -- or ship your exchange item as has been prearranged."

Really, stop acting as PR person for companies and start to advocate for consumer rights here.  Demand that they provide measurements of two audio gear, one with their cable and one with a generic one.  See if the output of your audio system actually changes.  Don't fall for empty claims for the cable.  You don't stick a digital cable into your ear and listen.  You listen to the output of your system. 

And to be clear, there is no way, no how that digital cable improves the sound of your system -- with or without break in.  I will donate $1,000 to your favorite charity if you can properly demonstrate otherwise.

I have added my main listening room components and front and back walls of that room. I have a small amount of reverb, corner echo which the center cloth absorber eliminated. My room isn’t as near perfect like the two @Kota 1 examples show but it’s pretty close.  I feel sorry for Mike for letting Amir in.  In all of the systems I've heard, no one wanted to give me measurements of their room/system/performance and I didn't ask them either.  No one cares, only Amir/ASR members.  Mike is too nice.  

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. The SR Atmosphere X Euphoria was the obviously best cable with no apparent colorations/neutral sounding, bested or equaled all other cables in every sonic aspect. Well worth the money/$1500. However, Grover Huffman’s very inexpensive digital cables $200? are quite good and came in second, mostly lacking in depth, it’s forward sounding. For $10, Monster Cable’s digital cable was rather bland but neutral, lacking dynamics mostly, okay resolution and okay, not great ambiance/depth/width perseption.

@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. The manufacturer or dealer likely feels the return rates are low enough that the policy is profitable since it attracts new customers that otherwise might not try their products..

As a customer I prefer to deal with these types of companies, YMMV.

Just for you @amir_asr you are as much science as the wagon peddlers in the old west.
