A bit different to my findings here...

The Tsunami gives much better RFI reduction than the Eupen or dearer RA Kimber leads I've got to hand for comparison.  Well at least that's my conclusion going by the least hashy sound it gives on the digital components compared to the other two.

My power amp should like the Tsunami but it doesn't.  Not enough dynamic current delivery for it, so something else gets used instead.

Just for a laugh, I tried the RA Kimber power kord on the computer monitor, as I had a spare one lying around doing nothing.  Nothing new to the a/v guys who know the benefits of such things I guess, but even to my rather lazy eyes I can see a difference...  blacker blacks and much more vibrant colours and a rock solid stability has been gained to the whole image - it's like somone turned the contrast control up a notch or two .  So if the Tsunami is long enough, maybe Ian should have a go with the PC screen too !!
