A good friend sent me a Shakti Stone "Air" (the new model that Shakti has come out with) and I set it on top of my ZROCK2 (best fit in my system for it) and left it sit last night and listened to the system today. And then another Shunyata Research Defender arrived this afternoon so it's in the outlet with the power cord for my PS Audio P15 now.
Both have made an audible improvement to the sound. The "Air" has given me a sliver of additional soundstage detail, welcome in this system. The Defender has given me a tiny twinge of rich darkness, also welcome. Both have given a sprinkle of punch--bass drums kick more, percussion has more of a sense of hands on skinheads.
Very happy to have moved another few steps up the plateau I have been traversing.
