    Lol - now you're just being pedantic!

    Ah - well there we disagree. I think it *can* be significant, and I've experienced the effect many times. It's one of the reasons why so many filters exist on the market to combat it.

    So what would you proffer as the reason why the mains lead supplied with your Hegel improved the sound of your Brio - and fairly significantly, too?

    Mmm. I'll have to search out a response as good as the ones for "having an open mind".

    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 RŲst 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.

    A typical kettle takes between about 1.5kW and 3kW. That's a lot more than most hi-fi power amps. It's maybe 100 times as much as a pre-amp or phonostage needs.
    If audiophile mains leads make a difference it's not due simply to their current carrying capacity.
    That's why we are having a discussion about the subject to see if anyone has an explanation.

    My take on it is metallurgy plays a major part, especially so when we are talking about OHNO casting and pure silver. The what, why and when is beyond my knowledge.

    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.

    It's beyond anyone's knowledge which is one of the reasons why people are so sceptical about the claims of improved sound quality.

    The other reason is that they have probably tried a fancy mains lead for themselves and heard no improvement whatsoever.

    What for you is defined as a "fancy mains lead" - would the likes of what Oliver has just built qualify as such?
