motion_blur,

You can download the results of all listeners and compare them with yours. http://listening-tests.hydrogenaudio.org/i...ous/results.zip
They are too different.

Also why do you post samples with samplerate 96 kHz?



Hi, Chris,
I had also hard time to understand the bootstrap analysis.
Please, wait for detailed answer on it

As of Christoph's results, all of them were excluded. http://www.hydrogenaudio.org/forums/index....st&p=751768

Some presentation suggestions:
1. Codec versions and settings should be in the results or one clearly marked click away. I don't consider what is now to be clearly marked.
2. Links to results of older tests would be welcome.
3. I can't wait for the bitrate table. wink.gif
