It is only a matter of taste. I auditioned the Puccini last week on y system with the U-Clock (I have placed my order) ;).
I done the audition with three power cords, all three made the Puccini sound very different, my first choice would be the Shunyata Anaconda (plenty of silence and very fast transients) second the top of the line Furutech, a little more "in your face" kind of sound, but very fast and musical, last but not least, the VDH Mainstream, less detailed and focused but definitely not on the same price range ;).
Beware, if you have the U-Clock, and you're listening to CD/SACD que Power Chord for the U-Clock is not important but things change when you're listening to your PC or MAC through the U-Clock !!! Here also Anaconda was my first choice...
