That a preferred vinyl recording could go thru an AD/DA stage and sound the same as if it didn't. So any preference one had for vinyl is not due to vinyl being a more accurate medium. The method is to have the direct phono preamp output, and an ADA stage signal to switch between and compare. sarvsa 1 And always keep in mind: Cognitive biases, like seeing optical illusions are a sign of a normally functioning brain. We all have them, it’s nothing to be ashamed about, but it is something that affects our objective evaluation of reality. Link to comment

A victim of my education and non-audiophile as is currently popular status. YMMV Looked at your links. Only the third, about the Strad, has any actual validity to what I was referring to, and is the same type of listening test. I'm not talking about a professional musician auditioning other musicians, I'm referring to some small difference we strain to hear in audiophile testing. Like does USB device A sound better than USB device B. I doubt the conductor, first violinist, or orchestra administrator auditioning a violinist feels the kind of stress I referred to. It's a different type of listening, IMO. And the better trained your ear is to hear the type of differences you are listening for, the easier and less pressured it is. Not trying to say DBT pr BT has no validity. But not every test is the best test for each situation.

Loads of fun with vinylphiles and digital-creates-drama-philes I've heard and read about demonstrations where a good digital transcription of an LP or tape can't be differentiated from the source-when played back over the same system. John Atkinson famously wrote that he listened to 192k digital transcriptions of from the Ayre QA9 ADC, and couldn't tell the difference from the source, even though he tried till his "ears bled". I think my present ADC setup is much the same. Whenever someone tells me how much better digital is than vinyl, that's the challenge I give them. If vinyl is superior and digital inferior, a digital transcription couldn't reproduce the "vinylness" enough to fool anyone. esldude and kumakuma 2 Main listening (small home office): Main setup: Surge protector +>Isol-8 Mini sub Axis Power Strip/Isolation>QuietPC Low Noise Server>Roon (Audiolense DRC)>Stack Audio Link II>Kii Control>Kii Three (on their own electric circuit) >GIK Room Treatments.

Only the third, about the Strad, has any actual validity Wrong. They are all valid audio tests. All highlight why sighted, uncontrolled "listening" create purely biased, invalid results for audio. Quote I'm referring to some small difference we strain to hear in audiophile testing. What differences? That is purely presumptive and fallacious. It's wishful thinking that the "small" differences are "audio" real, thus must be then tested. Quote Like does USB device A sound better than USB device B. I doubt the conductor, first violinist, or orchestra administrator auditioning a violinist feels the kind of stress I referred to. There is zero "stress" in sitting on ones posterior listening to music. The only "stress" is looking the total fool when the audio results show squat. If that's the case, then yes, audiophiles should indeed avoid/evade reality tests at all cost. Quote Not trying to say DBT pr BT has no validity. But not every test is the best test for each situation. Correct. As I've said numerous times, if you want to find out whether you prefer a watch or a USB widget, no test is needed at all. Tests are only needed for objective verification, of things like sound, or audio, or speed, weight, etc. All objective measures. plissken, esldude and sarvsa 3 Link to comment

Not sure what kind of position the subjectivists needs to take for debate and dialectic with them to be kosher at CA. How about starting here? "4. Individually, remember to stay gracious" ---Archimago, "On Being an Audiophile, Rationality, and Respectability (Thoughts on the Hardware Audiophile Hobby)" he also writes: "Mature people discuss things calmly." https://archimago.blogspot.com/2017/05/musings-on-being-audiophile-rationality.html "Debate and dialectic" is something we could discuss, what they are and what are good rules of thumb for practice. I'm curious what you mean by those terms and how you have learned these practices. It has been my impression that your understading of what is meant by them may be a bit subjectively biased toward your own preferred approach, but I could be wrong. I've practiced debate formally. I'm sure others have here as well. I'm not sure that this type of debate is what we want here. Debate has its place when needed, as does dialectic, which I'd at least like to think that I've studied i(and attempted to practice) in some depth. I would prefer a more conversational approach generally for this forum, but am open to exploration. Teresa, MikeyFresh and Jud 3 Link to comment
