Transparent isolator vs shunyata guardian pro

anyone have experience with both the transparent 2541XL and the shunyata guardian pro 6? I have Linn Kairn pre-amp bi-amped LK100's into keilidh's, clearaudio emotion, and krell kavcd250.
Skip the boxes, swap out the Shunyata for a Transparent MM Powerlink reference or an MIT Oracle AC 2 PC. Those two power cords are the best way to deal with AC issues while doing no harm to the musical signal. All Shunyata products have a characteristic darkness and damping down of the sound. IMO, Shunyata does not deserve the lofty praise they have recieved and should be used with restraint.
