Guys,

I'm sure that the QED works well for Andre, so why should he change?

As for the MG Belden 1694A - it is very good (and superb value for money), but I've no reason to think that it would be any better than the QED Andre uses.

If you want the best performance in this application from a Mark Grant cable, and can afford to spend a bit more, then use a G1000HD: http://markgrantcables.co.uk/shop/in...roducts_id=165

It doubles up as a digital cable and uses the exact same Canare plugs as the 1694A!

Marco, for coaxial digital, impedance matching is essential. The use of 75ohms connectors and cable is mandatory if you want to match the digital equipments' designer specifications. And the cable used for digital is not the same for audio: the frequencies involved differ.

G1000HD are 75ohm ? It is not specified...

Andre's cable is very good. I didn't advice him to change, he would gain probably nothing of such a change.
My advice was for the OP.

Hi Dimitri,

I'm not doubting what you're saying - it makes perfect sense - but I've got both 1694A and G1000HD, and can say absolutely quite categorically that the G1000HD sounds much superior used either in a digital or analogue context

Look - Mark himself even recommends them here:

The above are miles better than the 1694A as a digital cable - no question

if you can make something up yourself, the Aircel 7 wire should be easy to terminate into some decent phono plugs (which I thought were 50 ohm anyway.....). It has a very wide bandwidth and is designed for very long runs with negligible attenuation. Surely more than good enough for the 0's and 1's in a metre or two of digital interconnect.

If evrybody used decent connectors designed for a wide bandwidth transmission, there are some chunky looking connectors too.

Bloody phono plugs...................................

P.S. Impedance matching usn't necessarily an issue as many manufacturers used to have their own agendas on this, from Meridian to Linn and back.....

I thought digital incons had to be 75 ohm and that they all sound the same. It's been measured, so it must be true.............

If there is anything overrated it's a digital cable, as long as it's built correctly with true impedance cable it's perfectly fine

A co-ax digital cable is transmitting ones and zeros. Either it gets it right (sounds good) or it gets it wrong (sounds bad). IMO.

S/PDIF was designed to use 75ohm cable and ordinary phono plugs. No need for 75ohm plugs.

I'm waiting for someone to say gold plated Toslink connectors sound better than non gold plated ones . . . .

You'll have a long wait. There are good and bad digital interconnects though. Whatever the reductionist theory you cling to, the process of subjective listening iss not avoidable for digital i/cs.

S/PDIF emitters/receivers are designed for 75 ohms connections (cable+connectors).
If there's an impedance mismatch (and there's always one), then you have reflections. Some zeros and ones don't arrive when they should.
