There are many reports on Chord Groundarays and CAD usb control plugged into CH P gear being helpful.
I own a few and like what they do.
Did you try or maybe even compare with Furutech clear line RCA, XLR, USB, etc?
Do you have any experience with blind caps on RCA, BNC whatever plugs being helpful for better sound with CH P?
I found out how to switch off unused inputs of my L1, so no need for blind caps anymore.
Any input about Chord Groundaray LAN, USB vs. Furutech clear line LAN, USB vs. CAD usb control in CH Ps’ many slots?
