I found the Regen to have positive attributes on the first two DACs I used it on, but it was negative on my third and current DAC. It was certainly component dependent in my system.
Try removing your Uptone Audio Regen...
I did and should have a long time ago. I have no doubt it is system-dependent and results will vary. With my Aurender N100H feeding my AMR DP777 with a Wireworld Starlight Platinum 7 usb cable, I discovered that once I removed the Regen my sound took on much more accurate tonal character.
My mistake was simple-I took the Stereophile review as gospel-I inserted the Regen with linear power supply and assumed it improved the sound. I was too lazy physically and intellectually to take it out of my system and trust my own ears, until now.
