good power cord under $200

Initially, I didn't care for it. Thought it bright/harsh. After some hours now it seems to have settled in and I like it. Have only the stock cord and a DIY to compare it to, however.

Shunyata Diamondback. I used this on my pre amp and it was great there. It also worked on the amp but I put the python helix there. Since you need it for integrated tube, I think this would work. My pre amp was tube. Every system is different though but this is the cord I'd look for in that budget.

my problem with the mac was it was slow and a little muddy in the bass.
