Well, I received the new power cords yesterday. I ended up getting three of them. I decided to plug one to each Manley 300b amp and one into my Shrimp pre. I got home relatively late last night, so I only listened for a short while and at very low listening levels 64db avg. I put on Van Morrison's Astral Weeks, an album that I've been playing a lot lately. The improvements were readily apparent. Normally, it would take a lot more juice to get the soundstage to be so precisely defined and so stark in appearance, but there it was. The noise floor has clearly dropped lower than I've yet to experience; so, instrumental separation, side to side, and especially front to back, really stands out. Most importantly, however, is the astounding clarity of tone that I perceived. Every instrument sounds more like itself rather than a reproduction. I guess that the most intense change is in micro-dynamics and tonal accuracy. These are just my preliminary perceptions, right out of the box. I am very impressed with the Zu Bok cables. I hardly expected a power cable to have such a positive effect on my components...
Cheers,
Ivan
