    Well....

    English is my native language. For better or for worse the thread is currently focused on moi.

    E-Stat let's revisit your post and BoldEagles subsequent response

    E-Stat:I have taken part in true ABX style DBTs and conducted a cable SBT at home. The obvious challenge with single blind tests is to eliminate any contact between tester and me to prevent any cueing. From the outset, I stated that I did so by having her make the switch while I was out of the room (I exit to rear door to another room between each trial) while she entered/exited via the front door and returned upstairs before I reentered. SNIP

    I was accused of being a "typical audiophile not understanding over 35 years of psychoacoustic data". Naturally, I asked this guy why he thought the test was faulty given the test methodology

    BoldEagle:
    --SNIP--
    Not all tests need to be done by blind or DBT to confirm the effects of a change. A measurment where the changes are of a magnitude known to be detectable works just as well; provided the nature of the measured change matches the character of the perceived change. In other words there is a valid pairing of cause and effect. Too often in this hobby, the cause and effect pairings are not valid. (I'm thinking of a coaxial patch cord test by a "cable guru" where perceived differences were attributed to the materials of construction, while the capacitance changes caused by those different materials were not documented or considered). DBT or not, the tests can lead to an erroneous, or at least highly suspect, conclusion. Which in turn leads to the issue of test design and the skill and depth of knowledge of the test designer. In a sci-fi story called "The Answerer", the last line was: "In order to ask a meaningful question, you already have to know most of the answer". This concludes my sermon for this Sunday.
    E-Stat:Amen, preacher! -nt
    I understand this to be Bold Eagle giving you a lecture on why your test may not be as sound as you think it is. You also felt the same way about it but thought it was directed to folks like me (not sure why) because in your response to RJ from the thread you excerpted, you said "The irony of course is that Jerry's sermon was addressed to guys like TAH for whom the reference was targeted. --SNIP--"

    IMO, you very well knew which post I was referring to but decided to play dumb.

    It's a listening test, you do not need to see it to listen to it!
