I feel we maybe drifted away form apples to apples here? The issue of polluted power out of the plug =//= the effects of mains cable shielding, no? :)
Well, if I eye my setup I see a clean tidy end of the room without sources of interference. You'll have your usual WiFi networks zipping about but all in all there are no obvious offenders outside of the setup itself.
The streamer draws no current. The Dac draws no current. We're left with the amp that at least draws some current and its mains lead should stand for the vast majority of the interference potential I reckon. It also sits awfully close to speaker cables and interconnects due to the form factor of the amp.
I'd wager the bigger factor in this case isn't shielding from outside noise, but keeping the interference emitting from the mains lead itself from affecting the lower level signals that travel right next to it.
I have no other way of explaining why the Röst would exhibit smaller differences when switching cables despite being the higher resolving machine.
Seeing as we're discussing this topic, I decided to see whether the same improvement was possible with other equipment.
I plugged the power cable into the DAC and whilst I do feel the soundstage benefits from it being in over the standard cable, I don't feel the improvements are as great as when I put it into the phonostage.
There's an improvement to the bottom end which sounds cleaner and better defined but other than that it's really not a discernable difference.
I really do think it's down to the sensitivity of the equipment in all honesty. I'll build a cable for the DAC because It has made a small difference.
Also checked my plug socket and yes, I was using the LH side anyway. Good stuff.
I also do not subscribe to the notion that any mains cable is capable of resisting or rejecting any inbound electrical interference. Any such interference would have to make your teeth fillings glow long before it could enter an active mains cable.
As for outbound energy from a mains cable there is plenty from the EMF energy travelling along it and when an EMF meter is held up to it the needle swings at full deflection at the 'nodes' along the cable's length, around every 40cm or so. Copper and steel braiding offers zero resistance to that EMF energy no matter how dense the weave is, so that is almost purely ornamental.
In my experience, that's a big part of the problem, combined with the crap, devices such as routers and Sky boxes [with their cheap SMPS units] chuck into the house mains supply - and a well-designed, screened mains lead, built for hi-fi purposes, can often help combat said interference.
That certainly will have a bearing on matters, and it's why you should always keep mains and signal-carrying cables as far apart as possible. I always ensure that's the case in my system. It an integral part of the 'cable dressing' procedure I adopt when setting up a system.Quote:

No mine is a poor man's version. This one is fancy
