Nearly all manufacturers do not advertise/exhibit their product measurements? Why?
After my Audio Science Review review forum, it became apparent that nearly the only way one can determine the measurements of an audio product is wait for a review on line or in a publication. Most equipment is never reviewed or is given a subjective analysis rather than a measurement oriented review. One would think that manufacturers used tests and measurements to design and construct their products.
Manufacturers routinely give the performance characteristics of their products as Specifications. Those are not test measurements.
I searched the Revel speaker site for measurements of any of their speakers and could not find any. Revels are universally lauded for their exceptional reviewed measurements. Lack of published manufacturer measurements is true for nearly every speaker manufacturer I've searched for on line, perhaps several hundred. Same is true for amps, pre-amps, DACs, transports, turntables, well you get the picture. Do they have something to hide? I doubt the good quality products have anything to hide but poor quality products do.
ASR prides itself in providing "true" measurements that will aid in purchase decisions. Why don't the manufacturers provide these measurements so that reviewers can test if they are truthful or not?
Then there are the cables and tweaks for which I suspect that there are inadequate tests available to measure sonically perceived differences but which objectivists believe don't exist or are "snake oil."
Well, please chime in if you have some illuminating thoughts on the subject.
I would have loved to see manufacturers measurements on my equipment and especially those that I rejected.
How to measure a room is a great topic for a new thread. All I would say is whatever software you use get a good calibrated mic. There is DSPeaker, miniDSP, TrueRTA, REW, and of course Audyysey, DIRAC and ARC. If this is a rabbit hole you don’t want to dig you can have a calibrator do it remotely such as www.accucalav.com:

As for checking out virtual systems there is a text box beneath each one with a link "read more" which expands it. The links I mentioned are embedded in the description of my system. As for the topic of "blind testing" it just isn’t necessary or practical. Look, I drop a component in the rack and let it break in for a few weeks. I take it out before the 30 day return period expires. If I can’t tell a difference send it back. If my face freezes in "grinrictus" I leave it in. The people who argue about blind testing are just using it as a crutch to win an argument. Look, you need a panel of "trained listeners", you need the proper setup to switch quickly, and lets not go there. If you insist the best you can do IMO is buy a ABX Comapartor from Van Alstine but without a panel of trained listeners it still amounts to a "Pepsi Challenge" to my ears.

Funny how you regress to passive/aggressive mannerisms when you get called out. Put the multimeter down and try listening with your ears. You might be amazed at what you discover. Go ahead and tell me that my "boutique" audio setup sounds the same with a $30 power cable and a $500 power cable. Go ahead and tell me that again. See, here's the rub. Once you know better, you know. And no one can convince you otherwise. So quit trying to "save the world" from itself, and try listening to the music. Your channel is a joke, pandering to fools who are desperately trying to convince themselves that their $500 (insert piece of equipment here) is just as good as a $15K (insert piece of equipment here). You ought to be ashamed of yourself, really.

BTW- If your room is difficult and you want a top shelf reference Earl Geddes is a fantastic resource, check this out. The title is home theater but the principles appy to two channel as well. If you use a sub check page 236 for setup tips. Earl's PhD thesis was on bass management in small rooms: Premium Home Theater Design and Construction

@fleschler please help me to understand what are you trying to say! is it about cables not measured / disclosed / faulty? Topic: "Nearly all manufacturers do not advertise/exhibit their product measurements? Why?" Post: "My neighbor and friend was ashamed of his system when I lent him ONE power cable for his amp."
