Tube Distinctinctions 'The Power Works' Digital noise mains power filter TD2414-MG

That's a sensible price compared to the multi thousand pound bollocks thats it there...

Hi Shane.

As well as my Pi, I run my preamp through one of these and it's superb, so yes. Definitely.

Preamp? I guess if you think it sounds better, then go for it, but I wouldn't be putting a preamp through it, as it won't be generating the noise that the filter was designed to eliminate, and you'll be raising the impedance of the mains supply to the preamp (which all filters do to some degree).

Like almost anything in hi-fi, it's a question of compromise. Eliminating the effects of digital 'switching noise', with DACs, significantly outweighs the slight negative effect of raised mains impedance, but not with a preamp, because it isn't generating any such noise in the first place, and so doesn't need 'filtered'.

In your system, I'd be plugging the RPi and (if you still have it), your CDP, into the filter. Nothing else

Oh, it's because I'm out of sockets at the moment due to a room reorganisation, that's all. I plug the plug bar in to the filter which runs the preamp through it.

I have wondered if I should make use of the wall socket on the other wall for other things such as HDD's and turntable. I've always heard that it's best to use one socket rather than two, (one being on another wall). Any views on that?

The preamp doesn't lose anything through the filter put it that way.

[Marco]

Try taking it out of the filter and plugging it into a normal wall socket, and compare the 'before & after' results...

Honestly, mate, that filter should have nothing else plugged into other than 'noisy' digital gear. Analogue equipment should be left well out of it.

ok, thanks dude. I'll try and route over to the other wall socket.

Anyways, the filter certainly does a great job with my RPi and CDP.

I did a little review of the filter here along with the Sbooster.

Marco, surely it works both ways? Stopping already polluted mains getting to a component plugged into it or stopping noise getting out from a component plugged into it.

I've tried it Simon, and to my ears, doesn't improve the sound of analogue kit. This unit works best in conjunction with digital equipment.

The whole idea of its design is that it filters 'switching noise', generated by DACs, etc, to mains earth, thus isolating all other equipment plugged into the same mains block (which the filter is connected to) from the deleterious effects of said 'switching noise'.

If the equipment concerned doesn't generate any noise of its own, then by plugging it into the filter, you're gaining no advantage; simply the disadvantage of the filter raising mains impedance, which can (and to my ears does) deteriorate sound quality.

The (significant) sonic benefits of using this device derive mainly from eliminating the effects of 'switching noise', thus improving the performance of items such as CDPs, DACs and streaming devices, and in turn isolating the remaining analogue equipment in the system, connected to the same mains block, from being polluted by the noise that those items generate.

Thanks Jo. All the comments from customers have been great.

Thanks
It is very good and a realistic price.
