As expected, blind tests are very tough and very time consuming, especially when listening for small changes in volume.....

I managed to complete only 6 blind listening comparisons this morning and I decided to stop as it already took me 30 minutes just to do 6 comparisons. I started to get impatient and seem to loss the ability to detect slight change in volume near the end.

The number of tries not yet reached statistical significant.

First 5 correct, last one failed. 5 out of 6 correctly identify which DAC is which.

Test song is Pocket Piano from this album:

The x16 started cold, was turned off for 12 hours. Tests started about 10 minutes after powered on. E30 been on for more than 3 days.

Wife is the one who helped me with the blind tests. :)

She flipped a coin each time to decide which button in RCA quick switch to press before I start my listening. She would make sure both buttons were unselected before she select the button.

I am going to call it quits while I am ahead.

Really, not worth spending more time to investigate as the differences are now too small to bother me. Time to enjoy music!

: p

Again, I thank everyone here for being patient with me and many for providing me tips and advises!
