John, why go retail when I can go wholesale?

I think my first epiphany about audiophoolery happened some years ago after spending some time with a guy who (at the time) was probably the biggest name in audio reviewing. Companies were made and broken at his whim. Very nice fellow, but... he was quite ignorant and proudly so. Didn't faze his readers even a little bit.

As he pontificated on the design flaws of a preamp we were listening to, it struck me that he couldn't even design an RCA jack.

That was the first step in my recovery.
 
Because a "reviwer"could not "design an RCA jack"does not mean that music fans are divided to either diy'ers or "phools".

Who claimed that there are "big names in reviewing"?Like them ("reviewers")are IMO only those who blindly buy whatever these "reviewers" say is good.We all know such people.

I am sure you can be reasonably flexible,but I believe you just don't want to,which is perfectly respected.Not everything is black and white you know.

Where did music fans come into this? Most audiophiles I've dealt with (definitely not all, but most) were not particularly music fans. Most music fans I've dealt with (definitely not all, but most) were not particularly audiophiles.

If one believes that (for example) wire has audible "direction" or that a jar full of rocks has magic audible properties, then one is a plain old fool, no odd spelling needed.
 
Your post has a tiny shade of grey colour at last (not just black or white) and that's good.Maybe the percentages are not the same as yours,but most music fans I know are also trying to improve their audio system's sound too.For me these are healthy audiophiles,and a good number among them are also diy'ers,musicians and engineers.

Can wine critics design a cork? Yesterday I was reading an interesting analysis in the National Interest on American policy errors in Pakistan and noticed the author is Anthony Cordesman, know to most here as a subjective audio reviewer. Painting the field as the domain of superstitious idiots supports jlsem's complaint.
 
SY said:
BTW, competence and intelligence in one field does not make one immune to being a superstitious fool in another.

I was using a familiar example to question whether it was a requirement in a critic. Off the top of my head I can't think of a field where the ability 'to do' is mandatory. For what it's worth, I agree the technical expositions not authored by guests writers are generally train wrecks in those magazines. Maybe working in media for a generation+ lowers the threshold of outrage.
 
The room is a large part of your sound. how can a real audiophile ignore it. In an average room once you get 6 to 10 feet away from the source, the reflections, room modes and reverberations acount for as much of the sound energy reaching your ears as the the direct sound. And so have a lot more influence than the power cord! And other than room modes theres nothing you can do about the room with your system other than moving the speakers and thats usually limited by other factors. Basic room treatment is not that expensive (if you DIY), but it takes some education.

And by the way, you can get rid of the 150hz room resonance with a jar. Its called a Helmholtz resonater, and the rocks adjust the volume which adjusts the frequency it absorbs.
 
Oh, what a precious dear you are.

Thank you.

I speak directly in person and don't give a sod for political correctness. Whether you were my brother, best friend, or someone I have never met except as a name on a screen, I will call it how I see it. If you wish to get offended fine.

My, what a precious dear you are. Where have I ever said I've been offended?

John

I'm beginning to think there must be some kind of political correctness motivated transference of suppressed racism in the direction of audiophiles on this forum. This kind of generalization is unwarranted; why don't you simply call out individuals who offend you and leave out the people you don't know or have never met?

Then what was the point of the above?

It's not a requirement in a critic, but it's a requirement in a critic who ventures to tell practitioners what to do- at least if that critic is to be taken seriously.

Not able to put that more succinctly, perhaps just to add: .... and wears his ignorance like a protective screen, because he cannot handle others who think they know more than he thinks he knows - especially in the presence of the very real threat that they do actually know more than he actually does.

Actually,to be fair with most reviewers,they don't really say to their readers what to do,mostly they end the review expressing their opinion.

Not pardonable enough, Panikos. If you are accepted by others as a person with a particular ability (because it is their right to by virtue of the positon you are in) your task is no longer individual only. You are obliged, within your ability, to lead by what is true and in the interest of your readership, otherwise you become just one more letter-writer in the magazine.
 
Hi John,
Some comments need to be addressed, and I am not really sure what you are trying to accomplish here. You are simply badgering another member (SY) for no apparent reason. Please, what is your intent?
All I can find in the archives relating to the 12AT7 tubes tested and sample size is the following:
SY answered that. However, another excellent source for comparisons made in a similar manner to what SY has done, that is aside from my own unpublished work, can be found in a book by Morgan Jones, "Valve Amplifiers". In this book, the author embarks on a very similar action in quantifying the differences between tubes of the same or similar construction. His method is scientifically sound and verified through listening tests where the differences can be heard.

In post number 466, I defined what it is that makes one tube better than another. This agrees with what SY is doing, and also Morgan Jones. I'm sure many other tube professionals do things in a similar way.

Do you disagree with this at all?

Designing a circuit that operates the tube where it seems to be the most linear (ie: has the lowest distortion) and well within it's ratings is the best design. After all, the refrain I hear most often about high end or great equipment is how close it approaches "a straight wire with gain". I'm not really sure why this mythical wire needs to be straight, but there it is. I imagine a slight bend wouldn't hurt anything as they might be worried about inductance there. A wire with gain with no noise or distortion. Well, the more linear a tubes operation is, the lower the distortion would be. This satisfies the common refrain about really good amplification - yes? In my definition of what makes a good tube, the point was made that consistency from tube to tube is desired (or each tube would have it's own custom circuit, may as well solder them in) and that they produce lower noise and react less to vibration than their brother tubes.

It is a fact that people claim to hear a difference. The hypothesis is they actually do hear it, so there was nothing really to be fixed.
They may or may not, depending on interaction with the associated equipment. Too many uncontrolled variables to draw any conclusions from. That is the basic problem with "controlled observations" from the audiophile community. The tests are never well controlled, especially the test subjects (judges).

Remember too, a tube with differing characteristics from another will react differently with the surrounding circuitry. This might be audible, but is sure is measurable and reproducible.

Now, why on earth would they choose trained musicians to use in the study without at some point making a leap of faith that musicians may actually hear differently than you and I? So then, why are serious researchers recalcitrant to make the same leap of faith in the case of an audiophile who has been comparing audio systems for upwards of 40 years?
John, people are people. Some may be better at certain tasks than others, but no one is perfect like a machine. We do not have a fixed scale to relate things to. In other words, we can only be loosely calibrated, unlike test equipment that can be calibrated to a far lower uncertainty. I am choosing my words here.

It's really not up to the audiophile to push forward with the study any more than the trained musicians in the study cited above had the onus on themselves to show they had a specific aural ability.
Sure it is! Not unless you enjoy being lied to and ripped off. Buyer beware man!

Has there ever been a serious attempt by researchers to organize and fund such a study?
Now that would really kill what's left of the audio market. Truth is a serious adversary to many of the manufacturers out there today.

It's not up to you or anyone else here to decide who owns the onus.
But John, you're the one who has been attempting to put the onus on anyone but yourself here! You are the one questioning, so I have to assume you have evidence (in the properly accepted definition) to the contrary.

When a challenge (such as Randi's) starts off as a simple one (compare Cable A to Cable B) then evolves into an entirely different one by adding a condition that Cable A and Cable B must measure the same, then all bets are off.
Hardly!
He had to put definitions in to keep the challenge to it's original intent. Basically, you have people saying that they can hear things that we cannot measure. Okay, so fine! Take cables that no differences can be measured and tell them apart. What is so outlandish about that? Are these golden eared people so worried that they need two cables that do measure differently to tell the difference?

I can say more, but I'm tired now.

-Chris
