I am actually aware that In the Fields has tried a variety of the benefits that such after market additions are supposed to deliver. And has plenty of Meridian and other equipment with which to test them. A brief search of posts here will confirm that.

And the difference between a box wine and a fine wine are pretty easy to measure in terms of the production. But you can’t compare apples and oranges.
I still go back to my original post here.
I always wonder with the question of replacing mains cables what about the very cheap mains cable that runs all over the house. I mean, it’s one solid core of copper. And it goes through a consumer unit with micro switches. How does replacing a tiny part of the mains cable chain with a flexible cable that can cost up to £7k make any difference to the sound when the first thing that happens inside a Meridian speaker is yet another fuse and then a big transformer? i just want to understand the science of these expensive mains cables.

So are people saying there actually is no science?
Roger Nichols - sound engineer and solidly scientific- made clear arguments for implementing a balanced power system. It’s easier to do in the States with a 110 volt system. Well, easier in that it’s less dangerous than with 240 volts as we have over here. But his arguments were based on the complete chain of mains delivery. Unless people are replacing every cable in the chain then what we are left with is the proposal that the short mains cable acts as some kind of filter. And if that’s the case, then it can be measured.
And if it’s about filtering, then the filtering inside the speaker power supply will be more efficient for a number of clear, scientific reasons.

And of course the power supply of a particular device like an amplifier or streamer can make a difference. You will see that In the Fields is very aware of that. But the cable? Let’s at least try to explain the science…
