Interconnects and non-believers

Thank you, prof. As a past participant in some eye-opening blind tests, when it comes to anything except speakers I always ignore subjective views and my viewpoint is "if you didn't hear it blind, you didn't hear it." Your last sentence is the logic I've always tried to express, but not as concisely. I hope you don't mind if I steal it.

(... if you think tests in which efforts to really control and account for known variables are unreliable...what in the world make you think tests with fewer controls, which allow for all sort of known bias effects, are MORE reliable????)

A repost

Here is the CANADA HI-FI reporter's take from the NORDOST cables bake-off exhibit actually performed live at TAVES.They stopped at the improving model bakeoff summit at the Valhallas (one below the Odins) with the inference that a move up the model trendline in improvement keeps going further to the ODINs

".....I had a chance to sit in on a couple demonstrations in the Nordost room, giving my feet a well deserved break. I’m very familiar with the benefits of high quality cables and use a full Nordost Heimdall 2 loom with my reference two-channel setup. That being said, I always find the Nordost demonstrations to be an “ear-opening” experience. Michael Taylor from Nordost demonstrated the significant sonic benefits of replacing an OEM cable with a Nordost model – in particular 1) a swap of a single USB cable, from OEM to Nordost Blue Heaven ($250/2m), to Heimdall 2 ($500/2m) and; 2) a swap of a single RCA interconnect, from OEM, to Blue Heaven, to Heimdall 2, to Tyr 2 and finally Valhalla 2. Along with convincing the audience in the room that cables DO matter, I’ve now got the bug to upgrade...."

PS

This is not just anecdotal 3rd party opinion.... I was there too as part of the '000's of witnesses in attendance .

>>>>I don’t think anyone actually made that particular argument. Which would make it a Strawman argument. The general argument against blind tests is pretty much the same as for any test - If a test results are negative no conclusions can be drawn. In other words, a test of a device or a comparison of two cables or whatever by someone in a given system is only One Data Point. As other tests are performed then other data points will appear, perhaps conclusions can be drawn then, with more data points.

Cables tests are particularly prone to error due to directionality of the cables, using new cables for the test, not allowing the cables to “settle”after changing them. For example. A clever cable manufacturer - if he was aware of cable directionality and break-in - could easily rig the test by using a brand new OEM cable or whatever connected in the wrong direction for the comparison. Follow?

I always ignore subjective views and my viewpoint is "if you didn't hear it blind, you didn't hear it."

That's absurd. Most of us hear things all of time, yet we're not living our lives blinded. That doesn't mean that everything we've heard is illusion.

Re the Nordost demo:

One can google some....*ahem*....”interesting” reports on such demos.

If we really wanted to test the claims,  a wise consumer would not want the Manufacturer/Advertiser to be in control of the demo and all the variables.  ;-)
