Happy New Year and greetings everyone! I know the folks here at Hydrogen audio have been around and back with regards to these tests... Nonetheless, I've been collecting data from around the audio forums since early Dec 2012.

Since early December 2012, I've opened up a survey to see if music lovers & "audiophiles" around the world can tell the difference between high bitrate ~320kbps MP3 against the original un-lossy-compressed CD audio. I'm only planning to collect data until the end of January 2013.

So far, I have >70 responses from around the world with 5 continents represented. Folks have been using everything from inexpensive (but good) headphones to megabuck separates >$50K for this. There's 2 weeks left so if you've ever been curious about participating in a blind test or just want to add to the dataset, here's your chance :-).

The "test" is relatively simple and consists of 3 musical passages encoded as "Set A" vs. the same songs "Set B"; one of which was MP3 encoded.

Come to my blog to download the music and fill out the survey:

Thanks and have a wonderful 2013!

OOps - the title should have read 'ends Jan 31'... [fixed]

I'm going to decline your invitation Archimago.
You don't want to actually post at a reasonable place like HA, you're just trying to get hits on your blog.

Ain't that a bit cynical?

I know this place is "reasonable" but just the same, I am interested in an honest evaluation for anyone who hasn't already tried a blind test or just wants to be charitable in devoting some time and let me borrow the use of their ears/brain and equipment. Although I love audio gear, I know most of the world doesn't care for the bizarre/cultish/tweaky nature of much of it (frankly neither do I!).

You'll note that my blog has nothing on it other than this. Also, I have no ads and I care not about the # of hits, haven't even signed up for Google Analytics or anything like that...

As of today, there are just >100 responses from around the world! There's about 1.5 weeks left so I would love to get more responses to beef up the stats analysis.
