Powercord to tame brightness and add musicality

I think the problem is with the Krell gear. I have avoided Krell as I have always found it to be too bright for my taste.

Thank you everyone for your inputs. I love my Krell system for what it is: transparent, dynamic, detailed and revealing. I used to have tube gears so just want some of that magical tube sounds in my current system. I do have dedicated lines and a conditioner.

The madness goes on...

Consider a Tube Preamp to add that magic back into the equation, I don't believe a powercord or even power conditioning can relax Krell control (and the brightness I have found in my past listening experiences) A good balanced conditioner would add some liquidity, plus as others have said the dedicated powerlines is a necessary upgrade.
