i'm currently running b&w nautilus 804's and htm1 center channel with a parasound halo c2 pre/pro with an a-51 amp. i just added a balanced power technology bp-2 unit to my system. all my components except the amp are plugged into the balanced power unit. the bp-2 and amplifier are both running off the same single dedicated 20 amp circuit. with the bp-2 in position i noticed a very immediate widening of the soundstage and much clearer high end and better defined bass. here's my question. i ran out of space on my audio rack so i have the bp-2 on the floor. i unfortunately ordered the unit with only a six foot power cord. the only room on the floor is to the left of my front main speaker (unless i leave the bp-2 unit on the floor in front of the television- not very good WAF). the power cord is too short. my parasound amp is closer to the power outlet and comes with an eight foot power cable. so i swapped the bp-2 and parasound a-51 power cables not expecting to hear any difference. unfortunately i do hear a difference. with the bp-2 power cable plugged into my amplifier and the parasound power cable running the bp-2 the high end is not quite as clear as it was before and the soundstage seems a little narrower. i swapped cables a bunch of times and i definitely hear a difference. i assume the differences i'm hearing is do to power limitation to the amplifier. the bp-2 power cable is 10 gauge- this is more than adequate for 20amps. the parasound cable is a mass produced generic cable- no quite sure what gauge though. why am i hearing a difference? i assume both power cords are properly wired since the amp and bp-2 are working with either cable. as long as a cable is at least 12 gauge this is fat enough for any 20 amp line, right?
