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.

A change in source equipment can have a major impact. For example, I recently heard a Modwright Sony 999ES in my system and compared it with my APL Denon 3910. I'm not going to do a shoot out review here...the two players have different flavors, yet are close in performance. I could easily live with the Modwright Sony 999ES. It has a relaxed musicality to it that I believe would be excellent in a system that is "too bright".

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.
