That comment is often repeated.
It is a truism of the data cabling/telecoms world.
(I worked for BT for a decade.)
It is a workable generalisation for people who build industrial and wholesale data networks.
It just doesnāt apply to hifi because:
- hifi systems are extremely sensitive systems designed to amplify subtle electrical changes.
- the effect of SQ data cables have in a hifi system is not about data transfer, itās about electrical noise entering the cables and passing into the hifi system.
I believe you that āThe engineer in charge of all dCS network and streaming specifically recommends the use UNSHIELDED cable ie CAT6.ā
What you do not give is the reason why he recommends that (apart from the above, which Iāve refuted).
The question is whether thatās the result of extensive empirical testing heās done with using posh and cheap cables of various designs and Cat levels on various items of dCS kit in various test systems in homes and at his offices?
Or is it just because dCS doesnāt want to provide an expensive cable, because they know it wonāt necessarily work in everyoneās house?
If itās the latter reason, then heās just pushing a company line based on underlying financial and business strategy reasons.
So it is misleading as an assertion on this thread where we know that different ethernet cables can and do make a significant difference to our systems.
I can also note that when I bought a dCS Network Bridge it came with what appeared to be a very cheap ethernet patch lead that was so badly packed and tightly folded that it looked as though it had sustained damage in one place. I didnāt even test it or use it.
Also, in the manual for that piece of kit it said that dCS supplied a very cheap IEC power cable because they assumed that buyers would already own and use much better quality power cables.
Finally, as dCS knows that there are lots of digital cable deniers out there, some of whom are very activist on the main forums, they may be afraid to admit that ethernet cables make a significant difference to SQ as it might alienate those customers who are ideologically opposed to such differences.
