I once had a fellow named Roy Riches visit. He headed straight to the consumer unit. He meant well, but I think he'd crossed the line. I'm sure there was also a bit of fuse-blank ****ery, but that was quickly removed IIRC.
Yes, I had the full RKR installed by Roy himself. He meant well and some of what he did made sense for a full old Naim system which, with an LP12, was his point of reference.
I knew Roy quite well as a hifi acquaintance and he supplied the gubbins (but not cabling) for my installation. I can confirm that your points are well noticed but he really was obsessed with his 'research' (which wasn't to be sneezed at) and yes, it was all predicated on Linn/Naim, though he never climbed their respective ladders and still had his old Briks in a tiny room full of records some 15 years ago. He was an avid collector and knew his onions, but in ways that have been mentioned, he could go o.t.t. However, his quest for the least impedance was sonically justified i.m.o.
