Well I am sure many will be interested but I am interested in what Jocko thinks, among others. I found something out by "accident" today. First everyone should know you can have a $10 or $25,000 Spdif coaxial cable terminated in RCA and it is not 75Ohm. That is old news. It may or may not be hampering your sound. Most likely it is. Some DAC's do not care if you use a coat hanger however, but few. So Many will use a BNC if they have it, most don't. Then ala Nordost 2018 you can lock a cheap RCA adapter into a BNC terminated cable. I found that this is much lower than 75Ohms. Closer to 50. Not good. So what I discovered is that if you terminate the cable 'only' with a Delrin Butt compression "F" connector. Absolutely not crimp or metal Butt compression. That will make the impedance vary in either direction almost always. So, once the "F" connector is on screw in a cheap F>RCA adapter. Tighten it with pliers and no complaints why BNC is better then. Do not overtighten and crush it. Now you have a cable which must be true coaxial to be 75Ohm with the "F" connecter on it and a RCA screwed into that. I recommend Silver over Copper if you can source it. It was easier to find long ago. Or just gold is fine. Now measure this end to end with the RCA at both ends. Use a MM and sweeping scope. Guess what? Now the RCA's, The whole cable is 75Ohm! I tried several to make sure. Maybe not exactly 75 but nothing is repeatedly. Especially once you have applied it. I mean like to a decimal point, at the most 2 Ohms up/down. So you now have a true 75Ohm coaxial cable terminated in RCA. Granted as I said some DAC's do not care. If people are using things like Jplay, Fidelizer, Audiophile optimizer then I will say having a 75Ohm cable is going to make at least as much difference for you. Or anyone, it is just a good idea which is why high end equipment has AES3 and BNC. The proper impedance is important but no RCA cable matches it. Skip the $25,000 Nordost Odin 2 I have right here and use the cable I just mentioned with Belden RG6B/U Quad shield. You, like myself may find it sounds better than the Nordost costing 25 grand or any other RCA cable. The Nordost is RCA into a BNC, not close to 75Ohm. The "F" connector somehow allows the RCA to maintain very close to 75Ohms. If not spot on. Even if you do not think you hear it for the standard by Sony/Phillips this is of importance. I have used it on an MSB Select with Burmester 69. On the other end of the spectrum I used a $150 Samsung DVD player and Oppo DAC. So I checked it out both ways. I heard it, you may not but it is still of importance. Albeit less on the MSB obviously as it deals with jitter better. Make sure the cable is 6 feet long and you are good to go. Now I am saying, skip any cheap or expensive factory terminated coax cables that end in an RCA. Unless they are terminated with a Delrin Butt compression F connector and RCA screws on. No factory cables do Afaik. You can actually get the cable at Walmart(Black Web), I do not know if they have the RCA's. The cable is less than $7 and online two F>RCA are less than $2. $10 cable I personally feel is beating all comers including the Odin 2. Unless I am in the dark and this is well known please excuse my stupidity then. I am thinking not only did I just realize this but it is not well known if at all. I could just be a complete idiot if this is common knowledge in which case my apologies.
