I have a TWL Obsession and a Digital American for my transport and Dac.A Cullen Crossover all on my ss amp.ZenWave psr on the tube amp,Audio Envy on the pre.I don't like the TWL cords on the amps and pre but the noise filtering they do make them perfect for digital components to me.The Cullen is very good, I don't think you could go wrong with that choice. A good solid powerful sound no matter what component I tried it on.
