My point is that audio gurus never do anything that makes a significant difference. They usually boast about things that make little or no difference whilst ignoring obvious things that would make a significant difference.
Regarding sensory testing can you please explain why it is necessary to know what equipment is being tested when the test is based on auditory perception rather than visual perception ??

If that's how you read it Hugh then you must have a guilty conscience 😉
Anyone can build an amplifier but to properly design one takes a bit more than the qualifications from the back of a corn flakes packet or the "audio guru" status that many claim to have 😉
Elitist nonsense is when audio gurus claim to have secrets that nobody else knows about and that you can only hear the improvements and never able to measure any of them. That's what I call elitist nonsense mate !!!

You may not of said that but that is my opinion. And what point are you trying to make anyway ??
Well, Snoopy,
It must have been one helluva upbringing!!
I wish you well in your job applications!
Affectionately,
Hugh

Actually your evidence for this is what ??
In your 20 years of experience did you manage to make any submissions to any credible scientific or audio engineering journals by any chance ?? Is there any references so we can check this out ?? I would be very interested to see your analysis on this matter 😉

I'm surprised noone brings up the regular posts we get along the line of "I am a final year EE student... how do I make a cmoy?"
If it was as simple as measurements and formulas there would be no need for the auditioning of audio hardware... Yet there are many things like lowther drivers which do not correspond to our idea of linear happiness, yet sound good enough to demand top dollar.
Even without being an engineer there is enough material available by now to build up a clear understanding of subcircuits and work your way out from there... How do you choose between a long list of CSS topologies that could all fit the bill for an amp design...? Listening...!!!!!

My own NS-1000M crossovers
Hi All
I spent quite a few months building my second NS-1000M crossover mod, or rather in this case total rebuild.
It's all wired up inside with short runs of QED silver and large WBT terminals. I didn't want the L-pads in the circuit so replaced them with a suitable 12watt Mills resistor for midrange and tweeter.

Isn't this a preferred result compared to sighted test where size/weight/color/cost/brand name/whatever biases listener into believeing they do hear the differences that don't exist ?
DBT is not perfect by a long shot, but sighted test is simply worthless.

Therefore, only a blind person is truly suited to a DBT. Sighted people generally have eyes open, closing them only for sleep.
Bratislav said:
Preferred to the options you mention, not preferred to other forums of testing, but then again, that depends on what your goal is.

My goal is to know up to what point I can hear (as opposed to imagine) the differences between the components in question.
If I hear the difference under DBT, well, I know. If I don't, I can conclude the difference is so small that it most probably won't matter, so I can save for another record or a concert ticket.
Doing sighted tests is nothing but a delusion, and doesn't tell you anything about the components being compared. It might tell you something about yourself, but sometimes you wouldn't want to know about it 😀
There are ways of testing for observational differences that are probably more suited than DBT. Just to clarify, DBT done correctly is not biased towards null results. DBT as employed in most scenarios is.
Trust me, you won't find me making proclamations of huge differences by placing a Totem Beak on my speakers or some magic wire, but I'm not going to allow myself to get trapped into way of thinking that most extreme objectivists have which leads to even less progress than some of their subjectivist counterparts. Falling back on the "impossible! prove it! and only use my form of testing that is bound for failure" idea is counterintuitive to making progress. Unfortunately, the subjectivists generally have no motivation to experiment and objectivists would rather post on the internet about impossibilities and we get stuck at an impass where neither side is making any contructive discoveries.

Let's say you replaced your speakers wires and there were no measurable differences and you had the facilities to attempt a real DBT at home (i know of only 2 people wiht the facilities to pull this off out of hundreds of audio "friends"). But when you listened to these speakers in a casual setting, you system just sounded better than your system did with your last set of speaker wires. Now let's say they were the same price, can you convince yourself to back to your other wires even though they provided less enjoyment because that additional level of satisfaction was just imaginary?
I'm all for spending money wisely, and 99% of the tweaky system stuff is not what I would consider a wise investment of money, but I try to keep an open mind about the possibility that we can observe differences that can't be tested effectively with conventional means.
