The XC series are to be used with power distribution /conditioners only... I use the Alpha v2 nr’s on all of my components and they sound wonderful...no listening fatigue at all...
From the Shunyata Research applications page...The Alpha XC is an ideal power cable for your Shunyata Research power conditioner while the Alpha v2 NR provides noise reduction for all of the source equipment like CD players, DACs, tuners, amps, and preamplifiers.
Your Pass is a very fine amp and would have been better suited with a Alpha v2 NR instead in my opinion.
Maybe you should have tried it on your Puritan Audio Labs PSM156...
