Cable dressing is an often-ignored issue. Given that it takes time instead of money, that may look surprising, but there are so many variables.
In my case, I think the biggest benefit of switching to WH Morgana cables almost everywhere was that cable-dressing seems now to make so little difference - unlike my original Naim leads, where lazy dressing gave hums or blurring waffle or both.
Otoh, having a signal cable (for example to a phone stage) twisted around a power lead would still be very bad for SQ, no matter which cables and no matter how shielded they are or are not.
In my case, the Hydra body and shanked spare cable live under the rack. That makes keeping signal and power line separate a bit easier - another benefit.
Over the years I’ve tried different versions of ‘hydra’. In all cases I became annoyed with the limitations it put on cable dressing, I could never get it tidy and always ended up poking a leg or two into a coil or hiding place. I once read it described as akin to wrestling an octopus.
Now I have a dist board that’s wired LN&E in radial, and with decent sized wires to each socket. Plus individual equipment items fed with cables that are bespoke fitted to the required length.
Dressing heaven, tidy and as good as it gets SQ.
So saying that I will be better off using the Matrix 2 with either the powerline lite I already have or with a full fat Powerline if I can get one used?
Or with one of the Wireworld mains cables which are 3mm?
