i have the NuForce 8.5 v2's.
the rest of the system:
adcom 750 preamp
sony cdp c555es disc changer
psb stratus gold i
lat 1000 speaker wire
adcom 515 power enhancer
very average interconnects - audioquest ruby
straightwire rhapsody
original power cords for the amplifiers
original power cords for pre amp and sourceThe sound was astonishing clear, soundstage wide and that total silence from which sound eminates was deeper particularly on older redbook cds 
then, of course

i had to improve it.
i kept the same source, pre amp and speakers.
the cable company recommended:
audience power cord (non "e" version) for the pre amp
cardis quadlink power cords for the amps
i put in a furutech outlet
added a ps audio usb 200 power center
changed all the speaker wire to anti-cable from paul speltz.
my soundstage has flattened, highs once again are too bright, imaging is downright depressing

H E L P -
i'm thinking .... :idea... maybe
bypass the ps audio 200 and go right into the furutech outlet.
get NuForce interconnects (go with balanced) and speaker cable.
but really ..... i'm writing this to all those NuForce converts out there who might be able to tell me how, in the first place, i got it so right and how, in the second place, got it so wrong.
please help. every day without that which i'm suppose to have is a torture of sorts, principally because i had it.
