This is what I do as well. I have digital subscriptions to Stereophile and TAS and flip through them every month to look for new music to buy. Hi-Fi News out of the UK also has good music reviews. I rarely, if ever, read an article unless it's focused on music or the making of music.

I don't mean "you could do this ... handwave" ... I mean the actual distinctions that a person can make within minutes by listening. I didn't mean to drag Stereophile into this, aside from the fact that the measurements given tell us nothing that would actually answer the question. AFAIK, the actual amp designers use a combination of researching parts specs, modeling, building & measuring as well as listening. No one has given me an iota of convincing reason why I shouldn't similarly do research including read reviews and lookup measurements, and then actually listen before purchasing. Without getting into a bunch of prose, I consider the "J2" more accurate and this was apparent after listening for a few minutes and this has been borne out over time. I felt no inclination to do measurements to prove this to myself. Now if I were building one or the other and the sound wasn't identical to the real thing then yes I would do measurements. Nice.... Of course, it's the anti-audiophile trolls whose goal is to argue on the internet; read about others (poor tests) measuring results. Then, extrapolate that to the/a whole system in the room. No proof will ever be adequate for them, as they will never, ever, in their life allow themselves to sit down in front of a system or enter the gates of CES or any other "event" or test. (It becomes a naysaying religion). And back to Jud's OP; the answer is trolling, and the release of their anger & frustration that they have pent up from their daily life... Chris is correct in that no one will convince anyone of anything, - so they turn to sarcastic, generalized, insults, - as direct ones are not permitted. This becomes a very thin line: as this is 98% of an audiophile site, - a brief glance at the review list, or of the items discussed in the forums reflects questions & reviews about the products and people who want to enhance the recorded event listening experience.

So the more you know, the more biased you are toward the facts, and this is a problem? I’m not being completely serious - you still have to be aware your design may not perform as expected. That’s of course why people test, measure, and listen. Since very, very few designers are equipped with full research labs plus people to serve as blind testers plus people familiar with blind testing protocols and research to run the tests for them, much of the equipment you and I own may have survived all the tests and measurements, and then the people who listened to the prototypes that got that far may have been influenced by all those objective tests and measurements. I don’t find myself overly much bothered by that. jabbr and Teresa 2 One never knows, do one? - Fats Waller The fairest thing we can experience is the mysterious.

First, - FWIW, - I am not including you in the "anti-audiophile" group. On Accuracy: undefined, - it becomes a moving target. My friend the producer had a very valid argument as to why the Sophia was more accurate. And maybe it is more accurate. Beyond coming to an agreement on the definition of accuracy: the speaker and its measurements don't exist in a vacuum of accuracy or not. The amplification, source, & room also can play a role in making a speaker more accurate. And, that's not even mentioning the recording. It is why several, and certain speaker and amp manufacturers very strongly advocate certain brands of gear that "perform best" with their components.... And who we are is not static. Accuracy is not static. We LEARN that a recording featuring a Stradivarius is more accurate by hearing and comparing those violins live, and knowing the difference between a Stradivarius and a Yamaha. And whether or not the recording & the playback gear make the instruments sound right. We don't have "golden ears," - but we do know when a Stradivarius sounds "right." The best way to know this is to pile up listening experiences.... ""Designers are engineers, not artists." Designers are engineers who build ARTISAN PRODUCTs. Properly combining synergistic components enhances the art. ""The art is in the music." and the recording. Teresa, Superdad and jabbr 3 Link to comment

esldude Posted June 30, 2017 Share Posted June 30, 2017 One millionth of a watt. Yes, ONE MILLIONTH of one WATT! The link to the rant about low power. I think the fellow stated it poorly, but in context of his rant, I believe (perhaps incorrectly) he was referring to listening levels of about 80 db and the low level details some 60 db lower than that. So we have the 90 db at 1 watt at 1 meter speaker. Someone noted he needed 4 watts at a distance of 4 meters to get 90 db. True, if one were outdoors or in an anechoic chamber. Indoors with reflections it would be somewhat less than that. Also at 80 db one only needs about 1/3 of a watt. So yes it is quite likely that in room at 3 or 4 meters one will get about 80 db with a watt or maybe 2 watts or maybe not quite a watt. So what about 60 db lower? This is where you have low level air, ambience, and fine detail. It is these details which can give sense of size, and space and dimensionality of sound. If amplifiers differ in how this is handled vs high level signals these aspects of listening to good recordings could sound very different. 60 db lower is 1/1000th the voltage and will result in 1/1000th the current which both combine for 1/1,000,000th the power. So with the above speaker depending on room details we would have 1 millionth of one watt or two watts or perhaps a touch less than a watt. I also would note I once posted some music clips with noise added at various levels. I think I put up files that had noise at -40 to -90 db in 10 db steps. I asked people leave their volume in its usual position and listen to see at which level they could hear the noise. Most answers were for -70db with some at -60 and one at -80 db. So those levels which would be something like a millionth or few millionths of a watt are audible. 60 db down is near the surface noise of LPs, it isn't far from the noise floor of some tubed gear if of fairly high power. I think the near audibility of it is part of the reason these have a bit more air, space and 3D quality for some music. So yes, really, one millionth of a watt is no hyperbole. You can hear that level of power over many speakers. semente 1 And always keep in mind: Cognitive biases, like seeing optical illusions are a sign of a normally functioning brain.
