In Reply to: RE: best digital coaxial SPDIF cable under $100 posted by Duster on November 03, 2016 at 17:25:02
>>I have also built a number of DIY Oyaide FTVS-510 S/PDIF cables, and all have been impressive within my digital cable collection.>>
which RCA connectors did you put to those DIY SPDIF cables? were they 75ohms, or not necessarily? to what results, in any case? TIA!

Paco, perhaps the KLE Copper Harmony rca will be good, as described in the link where it was used with the Furutech FC-63, and maybe it will give you what you are looking for ... "the best digital coaxial SPDIF cable under $100".

thanks! i read those reviews... i may try, but with Oyaide wire
The notion of a "true 75 ohm" rca connector is often considered an oxymoron. What matters is how a 75 ohm characteristic impedance coaxial cable is terminated with an rca connector design and termination method that allows the round shape and diameter of the coaxial cable dielectric to be maintained from end to end, since a uniform relationship between the outer shield and center conductor along the entire length of the coaxial cable geometry is a vital aspect to keep cable reflections to a minimum. I prefer to use the term "75 ohm friendly" when it comes to rca connectors that are acceptable to use for an S/PDIF digital cable application when carefully terminated. Among those rca connectors I found to perform well with the Oyaide FTVS-510 are the WBT NextGen Ag, Jelco RCA PP-42, EIZZ EZ-201, and Xhadow Precision RCA. While the KLE Pure Harmony rca connector with a low eddy current design is better optimized for 75 ohm applications than many, I did not find it to provide good synergy when used with the Oyaide FTVS-510, to my ear. YMMV
A key example of an "unfriendly" rca connector for a 75 ohm application are typical 2-piece ground rca connectors such as the Canare F10 (not to be confused with the Canare RCAP-C3F crimp plug) with a strain relief mechanism that is intended to be crimped with torque around the end of the cable in order to secure the connector to the cable, which can deform the dielectric in a manner that may create substantial cable reflections as a result. Connectors that feature gentle strain relief designs or no built-in strain relief at all are better options for 75 ohm characteristic impedance applications. Another key factor is to choose a length of coaxial cable that better manages cable reflections rather than allowing strong signal reflections to degrade the signal transmission. While this particular issue can be cable dependent, 0.5 meter or 1.5 meter lengths tend to be a safer bet, at least from an anecdotal point of view vs. a 1 meter length digital coaxial cable.
thanks! i may try that Oyaide coaxial, but feel atracted to those KLE RCA connectors, after so much ink about them; only problem: how to solder that copper return to a V pin? did you add a small piece of wire joining them?
The bare copper shield that you are seeing in the image of the Oyaide FTVS-510 is a thin copper foil shield that does not need to be soldered to the return, since it makes intimate contact with the silver plated copper braided shield along the entire length of the cable, which acts as a drain wire for the copper foil shield. The braided shield simply needs to be flayed and twisted into a bundle, which is then soldered to the return.
thanks!

I am aware that you have had a bad experience with silver,but (as Duster said) they have a good synergy in a digital application.
That said:Today, a pair of Clear Day RCA ICs popped up on AudioGon.This 24ga silver IC with Eichman connectors has been my reference for a S/PDIF cable.
Since Paul/Clear Day will no longer build his cable with the Eichman (became too expensive),this is the only way to get your hands on this cable.
Originally,this IC was $185/meter pair.Just FYI.

thanks Tom, but i built an Oyaide silver with Kle connectors myself; i'll post a review rather soon...
I believe that the Oyaide DST-75R wire has a copper wire braid around the copper foil, which is not showing in your picture. If yes, and even though it is a different rca plug, perhaps this link will be helpful. Have a look at the following pictures.

thanks! very useful indeed...
I find the KLE connectors to be the easiest-to-solder RCA plugs around. The V makes it easy - the wire rests in the v and you solder it.
i agree, yet you seem to talk about TWO wires, but what about a coaxial cable, like the Oyaide FTVS-510 in the pic? that's why my original question...
Paco, have a look at these links, maybe they will be helpful, also ...
