Being a phyisicist, it is a bit mysterious for me how the quality of these SPDIF cables can matter at all but I accept the fact, anyway...
I am in a similar situation, need to make a few digital sound connections. There is a short one (same shelf) between my ASUS O!Play and a DacMagic, the other is a 12m one between my desktop computer and the DacMagic.
The prices of such cables are unbelievable and I could not find any in shops that are longer than 5m. I found a very cheap coaxial audio 5m one for something like 30CHF, but I would need three of these plus connectors which is still crazy. Another 1m one I found is sold for like 70CHF. I have zero experience, would like to lean towards the real cheap one but I just spent 4000CHF on my Hi-Fi upgrade and of course I don't want to ruin it with something low-grade.
If anybody has experience with making long digital audio connection, I'd be happy to hear any opinion. Especially, I am thinking I could surely just make (DIY) the cable out of the cable and two connectors ... or can I? Do you guys do it?
Thanks in advance
