Sorry I didn’t respond sooner, my internet was down.
It turn out it was only 2 of the ifii products, the usb3.0 and the itube2. The iusb3 did nothing and the itube2 sounded worse on all but one setting, don't remember which setting and that one did nothing.
I tried these on my old system, I can’t try the tube2 agin because it is RCA and my systems inputs are either XLR or optical now. I will try the iusb3 in my bedroom system this weekend and see what it does.
