The results you get from upgrading cords and/or power conditioners/regenerators will depend greatly on the weakest link in your system. Example: all those reviews on Audioreview by people who claim Martin Logans or Maggies.....are mediocre at best but power them with A/V receivers. Your components, however, should respond quite significantly to upgrading cords and conditioners.
I have found that upgrading plugs on cords also makes a big difference. Cheap wattgates do NOT sound as good as the Acrolinks, Oyaides, Furutechs, or IeGOs though it can be a balancing act choosing the right plugs. And I've even replaced all my outlets with upgraded ones. The Porter Ports are clean and clear and inexpensive making most others sound veiled. The Maestro outlets take performance up another notch being fuller bodied and presenting a deeper and more developed soundstage.
Keep in mind though that upgrading a single cord, while the other stock cords remain in the system, will only marginally improve your sound. The more cords you upgrade, the less compromised your sound will be and the more you will be able to hear the potential of your cords and ultimately, your system.
