The flaws of blind listening tests

Surely that happens often in hi-if. I’ve tried various footers under my amps but in each case preferred the amp sitting directly on the rack. If I hadn’t expected the footers to make an improvement I wouldn’t have tried them. They didn’t so I didn’t buy them, because my initial expectation was unfulfilled. 

 Have you ever tried putting a CD player or something like an Oppo media player directly on a carpet instead of directly in a cabinet to see if it sounds different ?

 I wouldn't expect a normal amplifier which doesn't have sensitive components like Xtal Oscillators to benefit much from using footers, however your preference for sitting the amplifier directly in the rack suggests that something is happening .

I presume that the amplifier doesn't use Vacuum Tubes which can sometimes be sensitive to vibration ?

just as the person espousing the 'artistic' language should realize that they use such language because - sorry to say -- don't know what they are talking about.)  There is plenty of room to learn -- on BOTH sides!!!

 

 

That is not the impression that I get from reading most of your lengthy replies.

 Please remember also, that this is an Audiophile site, where members should not be required to learn " Engineer Speak" in order to convey their messages/thoughts to qualified Electronics Engineers.

 However, quite a few members do have some experience in this area, despite not being qualified E.E.s , and a few like myself also have friends who are qualified E.E.s

  I am not trying to TELL someone that they need the results of my project, as I'll never make any money on it (far far from recouping the 2000+ person hours on the admittedly seemingly  impossible project.) 

 There does not appear to much point to your software unless it's for your own personal use, where you have identified quite a few CDs in your collection that were sloppily mastered for release , AND you play regularly.

 However, if there was made available a list of many of the sloppily mastered CDs that could be a different matter, with some people prepared to pay for the software.

However, being able to compile a list like that sounds a bit like " Mission Impossible"  too .

Both DolbyA and DBX I have their evils.   A lot of recording engineers really hate DolbyA because it creates distortion.  DBX is worse when it comes to noise modulation.  I am trying to mitigate some of the DolbyA evils.

Judging by the marked improvement with " ABBA-DayBeforeYouCame-DHDA" with a great deal of success !
