“The Pangea AC-14SE MkII C7 Signature Power Cable is well built and provides noise-free power to my MacIntosh headphone amp. Glad I bought the cord. The C7 plug is a bit heavy and bulky. When added to the weight of the cable, it seems like all that weight might pull it out since C7 is not a very secure fit. I might have to secure it to the Amp with tape to keep it falling out.”
