In Reply to: RE: Anybody have any experience with Furutech FT-111 RCA's? posted by Duster on March 30, 2017 at 14:35:20
Had some time to work on the cable last night. For me, the FT-111's are very frustrating to work with for a small diameter (ie: 23 gauge) wire. The wire wants to pop up to the side of the setscrew as it's tightened, resulting in a poor mechanical connection. Probably with a wire gauge of at least 20 gauge or larger this would not be a problem as the groove the wire sits in would keep it in place and prevent it from riding up the side of the setscrew. But for this project, I'm going back to the Harmony plugs and solder...I just don't have the patience to deal with the multiple upon multiple attempts it takes to get the wire to stay under the screw in the FT-111. Spent close to an hour last night working on one plug. Finally got it, but had to re-trim a couple times due to the stresses of the wire riding up the screw causing it to break. Way too irritated to do it 3 more times to assemble one pair of cables. I still think it's a very nicely constructed and quality RCA plug, just not very suitable for small gauge wires...at least for me.
You might try folding over the 23 AWG solid core wire to double-up the gauge (20 AWG effective gauge) which will provide more surface area for the set-screw, and keep the wire firmly in place. Simply strip-off twice the amount of insulation from the end of the wire, fold back the exposed wire in half to form a tight loop, then insert the looped wire into the termination area.
Good suggestion, Duster, but I tried that. It just separated and still climbed up the side(s) of the setscrew. With the way it's behaving, the bottom of the setscrew must be rounded (if even slightly), and I thought about pulling the screw out and hitting the bottom with a grinder to be sure it was completely flat. But by then my patience had left the building, and I'd already whipped out the soldering iron and Harmony plugs. Have the completed cables in the cooker now.
I'll hang onto the FT-111's as I'm sure I'll have some other creation with a larger wire to play with in the future.
A twisted pair of VH Audio's 21 AWG solid core OCC copper wire with AirLok dielectric doubled-up would provide 18 AWG effective gauge. The wire could even be flattened a bit with a smooth surface type pair of pliers or a hammer so it stays in place better for the set-screw to grip.
I've been curious what that wire would sound like as an interconnect. I might give it a try after I see what this gold wire sounds like. I'm going to give the assembled I/C's another full day cooking and a day or so to "cool" before I listen to them. Kind of excited to see what happens.
