This is very much the ND555 effect presentation - a few words that describe one of its sonic signatures.
It retrieves a lot more information and in the run-in phase I found that extra information could at times ‘trip-over’ itself and sound either harsh or blurred until over the weeks and months it all settles-down into a seamless full-bodied musical presentation.
My previous Ethernet cable experiments were to bottom-out what I can get from this as I believe the connectors plugged into the ND555 - all of them - make a big impact from what I hear. I already have SL analogue interconnect so apart from the Power Burndies (I kept my old CD555 ones) it was the Ethernet connector in my case.
People have recommended very expensive cables here and they may be worth it but I have so far found CAT5 utterly slaughters CAT6 and CAT7 and at least another multi-thousand pound HiFi Ethernet I tried.
To be fair at my Dealers we only tried between two HiFi expensive Ethernet cables as it was somehow presumed a special expensive cable would be better - and compared to standard CAT6 or CAT7 it probably is - but going down to CAT5 made the largest improvement in performance in my system.
To be clear it is not a subtle thing - better detail and bass articulation and clarity throughout with better musical engagement and smooth integrated presentation is what the 1m CAT5 gives - the other cables all do something worse.
For now I’m staying with the CAT5 until I hear it bettered. I will from time to time experiment but I don’t really feel the need right now.
The ‘noise’ in the cable mainly comes from the generation of the Ethernet signal itself so putting it inside a containing tube (the screen) and making sure it all reaches the ND555 (and probably reflects and bounces back and forth down the cable) may not be the greatest of engineering solutions from what I’m hearing - perhaps.
