Obviously Logans video of audio myths created a stir with audio enthusiasts. Most people agreed with what was said but the hardest reaction from the comments was do with mp3 vs flac.
Now there's a software program/plugin you can use to do a blind test between files its called a ABX Comparator. What I was hoping to do is to get a group survey of how well everyone is able to tell between lossy and lossless formats.
Just download foobar (http://www.foobar2000.org)
Then Downlaod & install the ABX plugin (http://www.foobar2000.org/components/view/foo_abx)
Add 2 different music formats of the song to your playlist, right click > utilities > ABX two tracks
It'll have the 2 songs mapped to 4 buttons, the aim is to match the same files blindly.
If you plan to give it a go, please post your results. Give as much detail about your audio setup as possible (DAC, amp, headphones or speakers), the song, quality of the files and where you sourced the lossless files from (cd, hdtracks.com, ect). There are just too many variables in audio.
I briefly compared Step by Vampire Weekend on my computer. Flac was sourced from the Album CD and the MP3 was 320kbps (CBR), I used my M50 headphones connected to a sound blaster ZxR sound card (all sound enhancements and EQ were turned off), I couldn't tell the difference at all, I failed every test. I tried multiple songs from the album and still failed. I haven't had a chance to try it with my proper audio setup yet though, which consists of a NAD amp/dac and my acoustics concept 20 speakers. But it's 1am where I am and I'm tired so I'll do it tomorrow and may be try some different music, tiredness also means there's probably stuff wrong in this post, like gramma, formating and other stuff so sorry)
Download ABX plugin http://www.foobar2000.org/components/view/foo_abx
Compare 2 of your music files
Post results with your audio setup, song and info about the 2 files you used for comparasin
Edit (07/01 6:10pm AEST):
Removed my comments about comparing bit/sample rates because someone claimed that the foobar ABX Comparator up scales the lower bit/sample rate. I haven't been able to find anything that confirms or denies this but for now we can't be sure. Even though I personally believe that should not make a difference it's not fair to act that my opinion is the only one that is right in a thread about hard facts and proper blind testing.
I'm a bit short on time but if someone is able to find a way to properly compare bit/sample rates played at thier intended and original rates I will update this post with the new method. Otherwise I will do my own research when I'm free next.

So far the best information I have been able to find is the foobar ABX comparator will convert both files to 32 bit PCM for comparison. Since both files are being unscaled to 32 bit, both audio files will be changed. This will not degrade quality but it will still change the audio. This also means that unless you are using the WASAPI plugin windows is going to be downscaling it again. Whether this has an effect your audio is up to you. But since both of the files you are comparing are going to be up scaled they are not going to loose or gain any details. The audio theoretically will be different from the original but since both the files will be different I doubt this matters at all in a comparison.
I am not an expert on this so feel free to debate, but for now it should be fine to do an accurate comparison between files of different bit/sample rates. Would also help if someone could find a better source.

The biggest argument so far is that windows is interfering with the audio, to remedy this I'm going to use a use an ABX comparator on a Linux OS. Im going to be using my AKG K702 connected to a NAD D 3020 amp/DAC.
I'll post what linux os and abx comparator I'm going to use once I have everything up and running. Tomorrow of course, its a bit late over here in aus -_-

Well after messing around with linux I was able to play my music at bit perfect audio, first impressions was that even without a abx comparator I was unable to notice any improvement from windows. It was definitely not worth loading up a whole new OS just to listen to my music. I'm pretty much a noob when it comes to linux because I personally haven't had a need for it but I've played around with it in the past. I had trouble getting the abx comparator to play nice with JACK, it was eventually taking too much of my time for something I was not going to continue even if the results were better. Booting into a linux OS just to listen to my music is not something I plan to do anyway.
This does not mean everyone wouldn't want too, if you willing give it a shot.

So here's a neat trick if you want to hear what audio mp3 removes from lossless. In Audacity load both your flac and mp3 files then invert the mp3. The audio in the mp3 that matches the flac will be cancelled out only leaving what the flac has left. Make sure to align the audio as best you can, if their not exactly synced the audio will not cancel out properly.
When I took my flac version of Unbelievers by Vampire Weekend (https://www.youtube.com/watch?v=2_qKmTLbEPc)
Then applied the method to issolate the sounds mp3 removes: http://tinyurl.com/ny9aq4b
