How much can be measured -- and how much cannot?

An understanding of measurements does more than just disqualify mismatched components. Some measurements will indicate specifically how those mismatched components will sound to some degree due to the them being mismatched, it's not just a matter of taste.
Some performance measurements will be more important to some than to others. For example, depending on ones location, a tuners ability to reject adjacent signals might be more important than overall sensitivity, and for others the reverse might be true. If one has to listen through static, everything else might be moot.
Let's not forget that some of today's measurements might be somewhat meaningless because they existed in the first place. There was a time, when not all gear "measured up" the same, but because of measurements they now do. It would be unwise to ignore measurements to the point that might happen again. I think we deserve more published measurements that can give us a better baseline correlation of audio components measurements and their sonic signatures. Perhaps published measurements of amplifiers propagation delays might be useful? How about more availability of harmonic distortions in frequency domain? FWIW, and though it doesn't necessarily exclude those that don't, I've never heard a speaker that publishes good measurements for either a good step response or clean square wave have anything but good imaging and sound stage.
Once again, measurements can be a valuable tool, but listening, though fickle, is more important...But, one doesn't need to choose between the two, both are more than the sum of their parts.
As to why the audio rags don't follow up on differences between subjective listening reviews and objective measuring, well, I suspect it's not in their best business interest. Let the buyer beware!:-)

Newbee,
Thanks for explaining. No problem.

I agree with you about not having enough experience. Years ago I was in the very same position you found yourself in -- not enough experience and lots of information trying to influence my purchases coming from various vested interests. This is a very steep learning curve that really never ends.

This has been a very rewarding if expensive process that is nearing an end because of serious financial constraints. But not only because of the latter. My system has got to such a satisfying level that I am at the point of diminishing returns. It would take a lot of money to get to a much higher level and I don't know if I did get there that all the effort and expense would translate into much more listener enjoyment because of the high level my system has reached.

It's time to sit back and enjoy what I have without chasing the latest and omnipresent breakthrough products with the attendant manufacturer claims. Over the years most of the improvements to my system have been what I would term incremental. Certainly, there have been some increments that have been more impressive than others. Some I would even call game-changers in their class. Nevertheless the effect on the sound has been incremental and improvement has not always come with the addition of an expensive component or cable. Sometimes even a very inexpensive tweak has given a wonderful improvement in the sound.

In spite of the impressive claims of even the most respected manufacturers in favor of a single component or cable being able to transform one's system, there has not been a single purchase that comes to mind that has measured up to the inflated claims of the maker.

Unsound,
The technical points you make are excellent and clearly explained. Regarding "audio rags", I would have thought it would be in their best interest to be as clear as possible although reading some of their reviews leads me to believe they seem to think otherwise. I will not name names but I think you will be able to easily find fine examples of unintelligible use of the English language by perusing some of the major audio review magazines. They often feature the most convoluted and confusing language that I can imagine a writer composing about audio matters. Florid language and audio cliches abound.

For the life of me, I cannot see how contradictory or confusing reports help the interests of audio magazines. They only lead to skepticism on the part of savvy readers, IMO. Each side of the coin in Stereophile reviews is valid. But if the two sides contradict each other and the review leaves it all hanging in mid-air it begs the question: don't these fellows realize their business is unfinished?

An example of this was the Stereophile review of Playback Designs MPS-5. Let me preface my remarks by saying I have no affiliation with Playback, I have never had any contact with them, I don't own their player, I have never heard it and I am completely neutral regarding it. I am not in the audio business and I have no connection with any audio company.

John Atkinson states at the end of his measurements: "So while I was impressed by the player's standard of construction, I can't say the same about its technical performance. The relatively high level of background noise limits the MPS-5's resolution with SACD and external 24-bit data to not much better than 16-bit CD. I am puzzled, therefore, why Michael Fremer liked the sound of this player so much."

Could John Atkinson not have picked up the phone and given Michael Fremer a call to arrange a chat and an audition together of the component in question? I mean, this seems to me to be a no-brainer. They work for the same publication. Are they not on speaking terms? You have one voice pointing north and the other voice pointing south and a little voice is heard in the background saying to their readers "up to you". How have they served their readers other than going to the trouble to confuse them? Frankly, I find this a very curious way for John Atkinson to end a review of one of the major contenders in the high end CD player market.

Unsound, when measurements were added to reviews I applauded it. However, I have seen little correlation between them. Nor have I heard good measuring components to sound better nor good reviewing components to sound better. Related to this is double blind testing. Having participated in several of these and having read critiques of the use of 30 sec. same/different tests in psychology, I find them invalid.

I really think that components should be sent to a known room where we have made a recording and had the performance digitized. Then we compare that component inserted into a known system whose measurements are known. We would then compare the change noted from both the existing system and the actual recording. The closer to the initial recording the better.

Screw all other measurements.

TBG, you've already posted that you've found some speaker measurements helpful. I can't help but wonder if upon further examination, you might find some correlation between some other measurements and some sound characteristics.
I like your proposal, very much!
Again, I think dismissing all other measurements would be imprudent.
