@w123ale not surprised about Cardas. I heard that wool warm blanket when I tried their Clear Beyond power cord. I’m sure it works well in some systems and sounds good to some listeners but I pass.
few things if I may…
In my experience, when it comes to interconnects, having the best set between the preamp and amp will get the most ROI. Speaker cables and amplifier power cord would also be at the top of the list.
I remember reading your post on Shunyata Delta NR v2 power cord on DAC. If that’s the power cord you ended up with, I’d recommend staying with the same level interconnects and speaker cables.
