What if a high end speaker measures really badly?


You know, it's true that I feel listening is more important than measurements and that it's generally difficult to really tie together measurements with pleasure.  Below 0.05% THD do I care?  No I do not.  I really don't care. The number tells me nothing about whether I'd like the amp more or not anymore.

In this one memorable review for the Alta Audio Adam speaker, I really felt shivers go up my spine when I looked at the measurements, especially at ~$20kUSD.   This looks like an absolute hot mess.  Does it sound this bad though?  I certainly don't have the $20K to test that out myself. What do you all think?

That is a valid point. It is interesting how one’s point of view affects the interpretation of was was written.

I was thinking more about the affect on "salability". That is where I was coming from.

Which is more influential, bad measurements or bad subjective opinion? My guess is the latter.

 

@helomech That is BS. Who trained them to hear that way. I would say fine, if they were a trained musician. Not supposed golden ears. I have been when a few were fooled by low-cost systems when they couldn’t see the system playing.

I went through taste training, when I worked at a distillery. I was not as good at others, that is the truth, so unless there is a standard training I don’t believe ’Golden Ears’ audiophiles. Since I know the rigor that goes into training ONE sense, that is standardized in the industry.

It’s true there is no industry-wide standard for listening, however, Toole and Harman have an established training and ability standard for the listeners it employs in its DBX comparisons. I would bet it’s similar for the wine industry too, you would probably see different standards had you attended training elsewhere (though the whole analogy is a straw-man argument anyhow, since we don’t hear with our tongues).

Regardless, I wasn’t implying that some of us are simply blessed with golden ears, I was merely pointing out the facts that 1) the majority who engage in the “hobby” are well into their retirement years, and it’s statistically true that most have suffered 10s of dB hearing loss relative to someone in their 20s or 30s. 2) I was also pointing to the poster’s mention of his experience with DIY and modifications, which the vast majority of audiophiles lack. Such experience can be very educational for correlating measurements with subjective sound quality. I don’t think it’s a stretch to presume the majority of audiophiles have never built their own speakers or designed a crossover, or even read some of Dr. Toole’s and Olive’s research for the matter. I would bet the vast majority cannot interpret measurement graphs beyond a simple on-axis impulse response.

Regarding experience, it also helps to purchase and/or listen to speakers for which 3rd-party measurements are published. For example, of the ≈35 speaker pairs I’ve owned over the last decade, there are published measurements available for at least 20 of them, probably more. So if I hear something offensive, I can subsequently reference the graphs to see whether there is a blatant or likely culprit (which of course requires comprehension of said graphs). More often than not, the cause is rather obvious if the measurement suit is thorough. Sometimes the cause is not so blatant, but that’s typically the case when the offense is relatively minor, or in cases of “sins of omission.” For example, if I find a speaker has a tendency to be fatiguing only after lengthy listening sessions, it could be that it has a driver break up mode that isn’t apparent without a waterfall/CSD graph or distortion data to reference.

Again, my comment was not to imply that some are simply gifted with golden ears and those listeners prefer textbook measurements. I was merely pointing to the facts that some have experience in correlating measurements to sound quality that many (if not most) lack, and of course, we all tend to suffer hearing decline as we age. So if someone in their early 20s tells me they are fatigued by a speaker that trends upward in the highs, I realize I may not conclude the same speaker is fatiguing to my ears.

I hope that clarifies the intent of my post.

 

I am lucky, because at 63, I can still hear 16K in one ear and 13K in the other since I have been in medical monitoring at work. I use ear protection and ear plugs when it gets too loud, like at concerts and work.

 

@helomech How many 'Golden ears' have been through that training. I bet one could count the number on one hand. That IS THE POINT. No standards.

I will no longer consider a speaker that has not been independently measured.  It is not that a good set of measurements guarantee a good sounding speaker.  I am looking at the measurements to understand the designer's background and motivation.  I want the speaker that the designer made for himself through a combination of good engineering and listening evaluation.  As opposed to made per the marketing department, or worse was designed by someone in the marketing department using a newly purchased copy of the Loudspeaker Cookbook.
