I should have added earlier. The addition of the chassis ground lug was highly welcomed. I added a Shunyata Altaira to my system last year and was using one of the top chassis screws to ‘ground’ my K50. It made a noticeable difference. The new ground lug is simply easier to use.
I have evolved to using a WW Platinum 8 USB cable and all ROON and have the best SQ I have ever had.
