Are you one of those who has got enough of bullshit of high end manufacturers and their false claims? They don’t even bother to give you proper specification, they rather stick piece of wood on it and give you spec like speed of light. I say WTF?
Specification of data transmission of S/PDIF says:
The receiver does not control the data rate, so it must avoid bit slip by synchronising its conversion with the source clock. This means that S/PDIF cannot fully decouple the final signal from influence by the analogue characteristics of the source or the interconnect, even though the digital audio data can normally be transmitted without loss. The source clock may carry inherent jitter or wander, and noise or distortion introduced in the data cable may further influence the process of clock recovery.
If people won’t be at least half lazy to google it or just don’t believe this magical aura of digital cables, world would be much cheaper place.
This is quick guide how to make your very own high end digital cable. No bullshit, just pure data 🙂
Belden 1694A is our all-around favourite coaxial cable, with superb bandwidth, low capacitance, and the best shielding (double-sided foil, overlaid with a dense tinned copper braid). Belden 1694A is useful in a wide variety of applications, from low-frequency analogue audio through the most demanding, high-frequency, high-bandwidth uses. Its specs compare favourably with any competing product on the market.
– £13.50 for Neutrik Profi RCA connectors (you can get hardly better ones)
– 2.50 / metre for BELDEN 1694A (from Canford.co.uk)
circa £20 (including postage) will get you great digital cable. Not bad for this kind of money heh?
You need only few tools to get yourself truly high end digital cable. Sure this is absolute minimum. Great soldering tutorials on YouTube.
Cable and Neutrik Profi RCA connectors is all you need. If you wanna make it more fancy, then braid sleeve is more than welcome. BNC connectors guarantee true 75 Ohm impedance, but neither DAC neither transport have this option. Oh well…
Cut cable with decent pliers. Make sure that cut is clean and you don’t damage cable.
First cut off outer sleeve, be very careful not to damage shield. (on this picture alu foil is already off). Again, decent cutting knife is a big advantage.
Connectors case has nice fool proof guide on rear side.
Twist outer braid and strip internal foam insulation.
You might wanna shorten braid, depending on construction of RCA connector.
Make sure you check out dimensions before soldering
Not my best work, but I haven’t been soldering for a while. I will do a job tho. Before you start, some practicing is advised.
Make sure you don’t have cold joints.
I have modified black plastic clamp in order to accommodate thick cable in.
Make most of it and measure resistance of cable, this procedure avoid cold/messed up joints. I always do that when making cables.
