Power cords Essence -Synerg-Ensemble

A Synergistic Reference has beaten everything for me, for either of my amps (KAV-250a, or Rogue 88). The Essence was only marginally better than the Pro Flo, so if you like the sound of the Essence, I'd save my money and get the Pro Flo. I haven't tried the King Cobra yet, but at this rate, it might be a while. I did like the SR much better than the Black Mamba and Sidewinder, and quite a few other cords. It's unbelievably better than the standard Master Coupler, to my mind. The standard one was slow and distorted, and the ref is just as dynamic, and seems to do everything else right too. I have no idea what amp you have, or what your system is like, etc.

ProFlo on my mono tube amps made a great difference, however it is still system dependent. Great value for the $.

Save your bucks til you can afford a used Cobra Powersnake(s). It is amazing! I'm comparing the Cobra to the King Cobra to the EG Fat Boy on my tube monoblocks. Though the King Cobra is very good and my system prefers the Fat Boys on the amps, the Cobra is the hands-down winner when it comes to performance versus cost. Some may actually prefer it to the King Cobra (original version), it is that good. Goodluck.

Almost forgot. The best cord under $500 is the Coincident powercord at about $275 new. It takes a good two to three weeks to sound it's best. As long as you don't listen to the Cobras, you'll love them. Goodluck.

Known name brands may or may not be fine, but overpriced you can pretty well count on. For some ideas on what MAKES a power cord good, why not look at the current STEALTH HAC power cord Audiogon auction? I have three of them in my system, replacing Classe and Cardas, and, especially after adding a dedicated ground, they improved my sound a lot. I would suggest the dedicated ground before ANY new power cord. Be sure to make it at least 10 gauge, though.
