I have a high degree of satisfaction with Furutech bulk cables, including power, interconnect and speaker cables, and I use them with very high quality connectors from Furutech and Oyaide. To summarize, I find them well balanced, and very good "all-rounders." They may not be the best in all areas, but they certainly get close to most of the better cables. They do not have any glaring faults, and they have the ability to sound good with a wide variety of gear, on a wide variety of music. The construction is of high quality and these are good enough that I would rather spend my money on upgrading equipment than on more expensive cables.
Regarding power cords, my amps run off of the unshielded FP-Alpha-3 with Oyaide P-79 connectors;
