Man, if we were to build cell phones instead of audio gear it would weight 5KG and have at least 2 toroids and RF output via a triode operating in class A
Duh!
Just ordered new BNC cable and BNC connectors..
oh well, I'll sleep better.

I have just had a quick run around and counted 17 BNC i/o on my equipment.
They were all put there for a technical reason.
I also have numerous i/o using the RF aerial socket again fitted for specific technical reasons.
All those manufacturers can't be wrong.

For S/PDIf indeed it doesn't matter, but -for example- HDMI/SDI is a whole different story altogether

it also does matter when you are claiming magical million dollar properties of certain RCA connectors… and if you can make it correctly for rather little money, as a DIYer, why not do so?
Some professional equipment, mostly intended to be part of a bigger system, do have BNC connectors. This is the typical case of medical diagnostic stuff.
SVHS recoders (now obsolete), printers, etc, have BNCs.
I guess one of the main advantages is that it can't break loose any easy.
I'm thinking that snake oil is quite an enemy we as diyers must fight back or surrender to idiocy.

Those BNC's are undoubtedly 50ohm, the standard for all measurement gear such as oscilloscopes, (apart from Video), and 10base-T data networks.
It is difficult to tell the difference between the two and they are often interchanged without realising, the effect being negligible except in demanding high frequency applications.

Attaching and detaching BNCs requires slightly more brain cells and slightly better manual dexterity than RCAs so maybe they are too complicated for the average technology user - or at least the average technology marketeer who makes the decisions?
Just out of curiosity it would be interesting to add poll with people deciding between for snake oil theories or against.
You guys make non believer out of me 🙂

I have another theory. BNC looks too much like a plain cheap antenna plug. Plus I suspect audiophiles to exaggerate the need for symmetry, RCA in/RCA out need be! 🙂
😀
yes this particular arrangement was what prompted me to correct the spelling instead of leaving it 😱 not that there's anything wrong with that 😉
I did almost report it myself to have it deleted. I mean I like my speakers and all, I have treated mine to Neotech UPOCC copper, but I have to draw the line somewhere 😛
Hi,
Last year i did some measurements on a few spdif cables with the equipment i use in my daily work designing, among other things, high speed data lines for mobile test equipment. The conclusion i made was that there was very poor correlation between performance and price.
I also did some characterization of the complete signal chain, from spdif line driver to spdif reciever and found that the design of my beloved music machines where less than perfect 🙂. The sad thing was (is) that even if i put a very good 75Ohm cable in the chain the results where a bit dissapointing. After correcting both source and reciever there was nothing beating a good double shielded industry standard cable both technically and sonically. I might of cource be a bit biased in listening tests towards the technically correct solution....
I will NEVER spend more than what a good industry standard cable cost on a spdif interface.
Extreme_Boky,
If you send me a cable i´d be happy to characterize it for you in my LeCroy Sparq 4004.

The issue is QWERTY. A BNC is a more reliable connection, but it's not in the installed base for this market sector.
Personally I would be interested in knowing what spdiff receivers/transmitters or way to..would be better technically. Meantime I have CD transports and powerdac with RCA and I can easily hear differences between spdif cables used and btw selected a cheap one for the time being, which also happen to be non-ferromagnetic as opposed to those magnetic Canare RCA's lol, totally unaceptable choice of materials for audioconnectors I read in another tread
Have you considered recovering the pulse trains after the pulse re-shaping/re-clocking stages inside your equipment, right at the DAC chip input?
How degraded the digital transmision has to be until the mentioned stages are unable to recover the data as it was sent?
Sorry but I thought that the whole digital audio was developed to allow overcome all analog downsides in regards to the audio signal to be transmited/recovered, not to continue suffering them.
There must be something seriously wrong with your system or some of the cables, or you were looking.irribeo said:
