Nice test, Pavel !

Files are not identical hence the difference.
MD5 for alaba3.wav 2092d5b11ddacd0f5262b3c51533c30a

MD5 for alaba4.wav d8b1feca77a2cdeff6e88e39bac312d8

Thank you, I have described the files and the recording here:
John Curl's Blowtorch preamplifier part III

It is this recording
Eric Clapton - I Still Do (Vinyl, LP, 45 RPM, Album) | Discogs
namely the Polydor Europe version. 45rpm vinyl.
Recorded at British Grove, UK.
Engineered by Glyn Johns and Martin Hollis
Mixed by Glyn Johns
Mastered by Bob Ludwig
Vinyl mastering by Bernie Grundman at BGM Mastering

So it goes, such are recordings nowadays. Please note I said not a word about sound quality.

Now the test files:
- one of them I made as a vinyl rip from this record myself
- the second one is the file issued by the producer that you may download if you buy the record. It is not a vinyl rip which you may easily find by file analysis at low frequencies - there is no vinyl surface noise added, but it has another issue at the high frequencies.

So, we have 2 very different files that can be seen in file analysis. It should be very easy then to get a positive ABX result, especially for those who can hear SOTA DAC differences, color of interconnect wires, resistor brands, capacitor brands.

I just did it without paying attention to which is which.......I prefer file 2 if had to choose which one to listen to.
It seems fuller/richer like a blues recording should.

Number one was sharper/more sterile to me.

I a/b’d them several times over apple airplay directly and at my regular listening volume

Gonna do a averaged fr to see if there’s measureable differences at lp

Edit....track 2 shows about 4db gain @ 50-70hz but other than that within 1-2db....93db avg @ lp

I've only just spotted this thread... and I found this one of Pavel's easier tests

They do sound quite different to me, and as mountainbob says, one is much fuller sounding.

Code:
foo_abx 2.0.5 report
foobar2000 v1.4.2
2019-06-19 14:32:05

File A: alaba3.wav
SHA1: f39d3480f6b532805b6ebbe09559f2449c0988c1
File B: alaba4.wav
SHA1: 447311ece0d37f804f328c1621df4599d6aa7aa6

Output:
DS : Primary Sound Driver
Crossfading: NO

14:32:05 : Test started.
14:33:10 : 01/01
14:33:15 : 02/02

Neither of them can be correctly heard,especially the analog one seeing we are listening digitally....

But I also prefer the 2nd file mountainman bob,it sounds more level and like an analogue recording would be..... (W/o the extra un-natural bass,etc) nut I cant really tell seeing im listening digitally.....


Whats the right answers on the files?? (Would be interesting to know)

I thought it was easier than I expected to pick a favorite between the two files. Using the Lossless Audio Checker, which can be downloaded for free here
http://losslessaudiochecker.com, it shows alaba3.wav as Upsampled whereas alaba4.wav is Clean.

It is outright deceit to put up this and not disclose the fiddle. Another for the ignore list.
