I had been thinking for some time that the VH Audio V-Twist when implemented as a AES/EBU digital cable must deserve more attention to its termination options. I gathered ChrisVH's favorite rhodium XLR connector may indeed be special when it comes to the V-Twist for a digital application. Since I've not been in a position to order a set of them, I rethought my decision not to use the platinum EIZZ Teflon XLR for a DIY V-Twist AES/EBU build. My previous impression of the combination was that the V-Twist sounded too analytical, not full-bodied, and that the platinum connector simply did not complement the more refined and delicate nature of the 24 AWG twisted pair. It occurred to me that platinum is in the rhodium family, so it should be more favorable than gold which ChrisVH does not favor for the AES/EBU application.
What seemed most divergent is the platinum EIZZ connector features set-screw termination slots with large entry holes, obviously intended for somewhat large gauge stranded conductors vs. a finer gauge solid core wire which swims in the termination slot, even when doubled-over within the slot. The rhodium Furutech XLR is a solder termination design which is better suited for a small 24 AWG solid core conductor, and it's not a proven fact that a solderless termination method is superior for a digital signal, nor line-level applications for that matter. So I had to make a decision to re-terminate one of my V-Twist AES/EBU builds that was previously terminated with gold Abbatron XLRs with the platinum EIZZ XLR, but this time soldered rather than use the set screws. It was easy to solder the wires, with no problem making a good solder joint. I had great hope for the new configuration, since a new DIY 21 AWG star quad (18 AWG aggregate) solid core OCC copper with AirLok dielectric DC umbilical I built provides such a strong sonic backbone that is of great benefit for the digital application.
The result is more than satisfactory. The V-Twist with the solder terminated platinum EIZZ XLR performs excellent, to my ear. I'm certain the build has captured more of what is favored by ChrisVH via the rhodium Furutech XLRs. In addition, the very firm sounding 21 AWG (18 AWG aggregate) star quad DC umbilical provides exactly what the V-Twist AES/EBU build needed to satisfy my wants/needs. Most notable are improved spatial cues and ambient information, and the delicate treble characteristics that my line-level V-Twist rca interconnects provide. It is too soon to say the build is my new reference AES/EBU cable, but I'm very glad to have made the decision to re-terminate the V-Twist.

First of all, I must correct my statement that ChrisVH prefers rhodium Furutech XLR connectors for terminating the V-Twist when implemented as an AES/EBU digital cable. It was a misunderstanding on my part, and I apologize for the misinformation. In fact, the Furutech FP-601M(G) and FP-602F(G) Gold XLR connectors are his preferred models for a balanced V-Twist AES/EBU digital cable application.
Taking that into consideration, I decided to re-terminate a set-screw terminated DIY V-Twist AES/EBU digital cable with gold EIZZ XLR connectors, and instead direct-solder the conductors to the termination slots as I did with the platinum EIZZ Teflon XLRs. The sonic result is similar to that of the 24 AWG V-twist when terminated with direct-soldered platinum EIZZ Teflon XLRs, but with a slightly laid back if not warmer sounding sonic signature that provides a different flavor to choose from as compared to the somewhat more assertive and not as warm-sounding platinum EIZZ XLRs. So the 24 AWG V-Twist cable sounds better to my ear when soldered vs. a set-screw method no matter what plating is involved.
These findings bring into question the possible benefit of re-terminating my DIY VH Audio 21 AWG OCC copper with AirLok dielectric twisted pair AES/EBU digital cables with set-screw terminated EIZZ XLR connectors, and instead experiment by direct-soldering the conductors as I did with the 24 AWG V-Twist cable. However, the larger 21 AWG solid core wire when doubled into the termination slot provides an 18 AWG aggregate gauge, which fits very firmly into the termination slot, with plenty of surface area for good signal transfer. Since I can't undo the modification, it will take more thought about the matter before I take a plunge to find-out what that modification might produce. I've been very pleased with that design option as it is, so I'll likely leave them as they are for the time being.
I don't understand using a 2 wire cable with a 3 pin connector.
Would you elucidate please?
I made an AES/EBU cable with 3 CCC vampire wires braided and I like it--proud Papa etc
Since a twisted pair is all that is required to pass the signal, I find the third pin to be unnecessary, A simple twisted pair provides better signal purity, IMO. There are some cases in pro audio that require and/or benefit from a ground wire, but I don't think it's necessary for a typical home audio application, especially for an unshielded balanced cable application.
I've never found set screws to sound as good as soldered. Also you should try taking the barrel off, as an experiment - I find most xlr plugs sound better without the barrel.
