Both my Bryston Bit-15 "Enormous Transformer in a Box" power conditioner (bought because it was on sale and has lots of outlets), and my fabulous sounding Pass XA-25 (among other components) are being used with the supplied heavy duty but NOT "boutique" power cords. I challenge anyone to listen to my gear heap and tell me why I need expensive AC cables. However, nobody can meet this challenge as I’m not letting them near my house, and if I find somebody has snuck in I’ll kick them out. That said, I do have a few large fancy power cables because I like they way they look.
