power cords fo monoblocks

What have you tried? What did you like and what didn't work with past components? What is your budget?

Signalcable.com ....Try the Magic Power cord! you will not regret it. It dosen't cost a bunch either. Tip...order 2 ft more than you need, the cable dosent bend easily.

+1 for Signal Cable. Excellent performance for the price!

If you are going to buy something without a demo first, ESP Essence and Richard Grey are probably the safest choices I can think of. With the exception of my Ayre gear, those 2 cables never sound worse than stock cords. That's very rare. Still, you should listen to them first.

I'm looking for cables that will add just a tad of warmth and also a benefit of a closer soundstage.

Have you tried moving speakers closer together or increase toe in for a closer soundstage?
