Power Cord suggestion please

The lesser expensive Shunyata power cords (or any other brand) as long as you are sure they will fit into your IEC. 
I definitely heard an improvement in the bass, with my Von Schweikert dB 99 speakers when I upgraded the power cords to the Shunyata Diamond Back power cord. I would think any good 12 gauge professionally made or DIY power cord should do the trick.

It would be a wonderful world if changing a piece of wire improved sound quality! Alas ...

@mlapenta,
You need a Cullen Crossover power cord, which is 12awg.
I have 2 Cullen power cords and ordered a new Crossover II for a new preamp in my system.

I have a crossover. Beautiful workmanship. I was and remain a skeptic, but may hear slight bass increases and better soundstage. Pat is a great guy.

I like Pangea and use them on everything. I have also made $400 (just the parts cost) powercords with OFC wire and Furutech plugs.. The Pangea are just as good.        
To any newbie postng a 'what should I buy': You should be suspicious of several posts close together promoting one brand. Usually those are shills or 'fan boy' posts. In all the history of Audio threads no two actual audiophiles EVER agreed on anything. When they DO.. you can be sure it is some effort to steal your money.
