Hi there Keith.I think I have made a gain with the furutech 20 amp iec on the amp.I'll know tomorrow for sure.I just started the stereo this afternoon. It wasn't hard changing out the 15amp,it did have a fuse in it,which the 20 amp hasnt got.I screwed the wires in yesterday and retightened them today,,which it does need,IMO.I have a voodoo wall plug here,I mite put that on, till the gtx arrives,just to know.It probably wouldn't hurt to have a gold and a rhodium wall plug,what do you think ? One component just mite sound better on the gold.Just a thought.
