Synergistic Research Euphoria HC power cord.

What sound characteristics/improvements are you looking for and what are you using now?

Sooo, what improvements and sound characteristics are you looking for?. That’s critical information. 

I’d recommend the AZ Krakatoa PC, and this one seems like a great value that you can probably resell at little/no loss if it doesn’t work for you. Reason I recommend it is because I have a full loom of AZ cables and their level of detailed yet natural and organic presentation is intoxicating, and the depth and 3D imaging/soundstage is outstanding and may save you a boatload of $$$ with little/no risk.

Alternatively, I’m gonna throw out a dark horse candidate that I think offers outstanding performance and value. The LavriCable Grand power cords are made of 5N silver wire and are an incredible value at $533 for a 2m PC. I’ve got several of their cables, and I can say they offer an incredible amount of detail and refinement but with excellent tonality silver cables often miss but with outstanding 3D imaging and huge and transparent soundstage. I think both @ghdprentice and @lak might have their power cords and maybe will chime in here, but I think this company is onto something and offering incredible value for the performance on offer. Whether you choose the AZ or LavriCable PCs I highly doubt you’d be disappointed either way and potentially save thousands of $$$ over the SR cable. Just my $0.02 FWIW. Hope this helps, and best of luck.

BTW, I just splurged $200 for a SR Purple fuse for my recently fully upgraded SMcAudio amp so I’m certainly not against SR products if that’s the way you decide to go. Just wanted you to know I’m in no way a SR hater, and their fuses came very highly recommended from SMcAudio, which is high praise in my book.
