Audio Blind Testing

[Ralf11]

Thx - writing style is odd; was it translated?

[Ralf11]

True, if a magazine evaluation, etc.  (or for Magneplanar deciding if they want to change an existing product).

 

These would be 'cells' in an analysis of variance design.

 

For a person testing equipment for themself, the number of interested audiophiles is 1.  Multiple tests should still be done.

[Ralf11]

which  ear-brain issues are difficult to control for?

Phenomena like stress-induced loss of listening discernment and audio memory.

 

I'd be interested in any citations to the literature finding either of the above.

[Ralf11]

Ron - do a search for SACD + meta-analysis here for a cite I posted some time ago.  It appears there a marginal improvement with SACDs over CDs.

 

GUTB - Thx for posting what you had.  But, it just isn't enough...

[Ralf11]

claiming it DOES exist with no evidence is a LOT worse

 

 

[Ralf11]

The time factor is very relevant when some golden ears guru writes a review of items months apart...

[Ralf11]

I've heard people claim that different masterings are often used for the Redbook layer on SACDs - anybody know for sure?

 

It seems like an odd thing for a recording co. to do...

[Ralf11]

not sure how time is being used in all the posts

 

but if the time difference between listening sessions is considered that may well make it more different for a listener to compare - most sensory phenomena (and their processing in the brain or elsewhere) are 'designed' to do comparisons

 

One good way to do listening comparisons is listen to one short passage on A, and then on B

- this is trivial to setup using 2 different CD players; not so easy with 2 different speakers

 

*** ...not to rule out extended sessions

[Ralf11]

comparisons are nearly pointless without DBTs

 

- there is a huge cognitive psychology literature about this, including cross-modal sensory issues, not to mention "label whore" effects in wine tastings, food tastings, and on and on

 

- the effects are not limited to humans but are known in other mammals and birds

[Ralf11]

Music lovers have no interest in DIY capacitor de-soldering either !!!

 

Your arrogance in attempting to make decisions for "Music lovers" is one of the things that earned you Audio Ayatollah status - a nom de diss I agree with.

[Ralf11]

Dear Audio Ayatollah - please don't mischaracterize me or my position

 

it just makes you look worse than usual

 

BTW, people can use meters to match levels.  Not hard.

[Ralf11]

you know who Bruce Rozenblit is, don't you???

 

 

maybe we should say Audiofools

 

you know, people who reject science and rely on speculation

 

 

[Ralf11]

Really??? Care to make a bet on that?   

[Ralf11]

you should start your own forum - maybe in Iran

True, but they should probably be interested in whether that $5000 cable actually makes an audible difference or if seeing the many zeros in the price tag causes a catastrophic failure of common sense.

 

I can guarantee that an assumed high price will make your wine taste better, and your cables sound better even if they are cheap.

 

The former was tested by scientists with remarkable results, and published in one of those peer-reviewed journals that some try to kick sand at.

 

Confirmation Bias is insidious which is why any prudent purchaser will take steps to guard against it.

[Ralf11]

it was proven that cheap $5 wine tasted as good as $90 wine when you are falsely told the  price was $90

.... All I am saying, the look, price, the room and brand reputation have a role to play in perception.

 

 

I have no problem if someone wants to pay extra for a look they like.  But the consumer needs to make that decision with full knowledge of what $$ put where provides SQ vs. ergonomics, or aesthetic visuals.

 

In act, ergonomics was part of the reason I bought my current pre-amp - it happens sound pretty good too (ARC LS25 Mk II)

... We need to have an open mind ...

 

 

We do experiments so our minds are not open like sieves

 

If you really want the citation to this study I can probably dig it out so contact me.

[Ralf11]

I don't think the Sommelier thing is just luck... people have done fNMR studies and found that when they taste wine the same brain regions are engaged as in novice tasters, but so are other brain regions, not used by the novice tasters (!)

[Ralf11]

yeh, that's why we need double blind listening tests

[Ralf11]

Most deluded people don't give a shit about Logical Fallacies, or for that matter the demands for DBTs every time a member reports an improvement due to confirmation bias...

[Ralf11]

I thought  GUTB's twin was fas2

 

[Ralf11]

be good and I'll give you back the 4

[Ralf11]

your entire posting history is mostly pointless debating and angry personal attacks

 

 

you know, ad hominem stuff
