@ironrick6 , I'm replying to your message here since Audiogon wants me to verify my phone number (ok...) and a payment method (why?) to respond to your message.
To answer your question, I'm currently using an old 75 ohm Audioquest video cable with an RCA->BNC plug going into the Qutest. I'm looking for a used Audioquest digital cable to see if that makes a difference. I would like to try the USB cable; however, I use an SSD plugged into the N130 USB port so I'll need to do something different to test that option out.
