Hello everyone!

I know some people have strong feelings about digital upsampling filters and there's especially the notion of minimum phase filters being superior or more "natural" sounding than the typical linear filters used in most DACs. The main reason given has been the idea that one can remove the "pre-echo" with minimum phase settings.

Here's an opportunity to try it out for yourself and let me know if you hear a difference! Come and add to my survey.

Note that the files are high-resolution 24/176 so please make sure your DAC is capable of this bit- and sample-rate.

Test will conclude on June 25th so please submit your results by that time. As usual, I want to compile the data and see if conclusions can be made empirically.
