I would give High Fidelity MC O6 Hemisphere a try. Cheaper in price than the Shunyata and comes with a 30 day trial for a full refund. Its down side is a long break in and only for your front end equipment no amps and no surge or spike protection. I have found amps do better direct to the wall. I have owned PSaudio PPP and their P10. The P10 was a big step up from the PPP in sound quality. The MC O6 Hemisphere just put out a better sound stage across the board once broken in.High Fidelity has some very high price items but their intro level stuff works very well.
