Yes I did. The problem wasn't so much the amp and DAC, it was finding something that used the same mastering in both DSD and PCM. It was also difficult to find a direct DSD recording. Most music on DSD is either legacy analogue recordings or commercial music engineered in PCM. In order to hear pure DSD, you have to find a recording that was recorded and mixed live. It isn't technically possible to mix using DSD. Usually, it is bumped to PCM to mix and then back to DSD again.
If you'd like to hear about my test, I'd be happy to tell you about it. Yes, it was quite difficult to set up.
By the way, if it isn't blind, expectation bias can affect your results. Expectation bias is real. In Sound Science, if you claim to hear clear differences between things that sound the same to everyone else, you need a blind test to prove it. I'm pretty sure your results were the result of either expectation bias or different mastering. I think you are chasing the wrong goal here. You are focused on theoretical sound, not sound you can actually hear. And you have misconceptions about how it all works.
