Lan noise reducer

I was thinking how can people who don't believe in audiophile power cables try something without actually buying an audiophile cable. I think I have a test..

Go and find a regular 3 amp UK mains plug fuse. Fit that 3 amp fuse into the plug that's powering your amplifier, let the amplifier warm up and have a listen to the music.

Then find a regular 13 amp UK mains plug fuse, then fit that into the plug powering your amplifier, again let things warm up, then listen.

You should find the audio sounds better with the 13 amp, as it's giving lower impedance. Of course you won't have any of the RFI noise reduction many audiophile cables give, but you should at least hear a difference from the change in impedance from the fuse.

Then once you realise the 13 amp fuse is better than the 3 amp, maybe you can appreciate how a low impedance audiophile mains cable would further the improvement again.

It would also help if you did the 3 amp / 13 amp fuse test with the amp plugged directly into the wall.

@JasonM I use to have a 4 way yello power strip and the RA block which is the same as yours. When my main hi fi was in use everything bar the power amp was connected into it. I have never liked my power amp connected to the RA block or using the RA power leads due I feel it dulls the sound ever so slightly. I understand the reason behind it, it is supposed to provide a more cleaner power and lowers the noise floor. But everytime I heard it off the RA block I was just nope and just went back to running it off the wall.

Come to think of it I pretty much don't like any type of power conditioner with my power amp and just prefer running it from the wall albeit with that being said I have not tried the Burmester main conditioner or the Ps Audio regenerator.

Was your RA block the same as this below?


What power cable did you connect to it? By this I mean the cable to the 16A socket that feeds power to it. It should be at least an 8TC reference / high-power cable or above, else it will degrade the blocks performance.

New Beatles song is being released, and it uses AI software to remove 'hum of mains electricity'

Strange really when around 80% of the people who posted in this thread believe mains quality can't effect audio. The sound engineers involved with the song must have just imagined this mains hum was present.

For Now And Then, the software was able to "lift" Lennon's voice from the original cassette recording, removing the background hiss and the hum of the mains electricity that had hampered previous attempts to complete the song.

That's a 50hz hum if present

Hardly rocket science or snake oil electrical magical things.

It was recorded in 1978, you don’t think that modern equipment might just be a bit better?

Mobile phones used to cause interference with speakers and computers and you could hear static before a call or text came in, that hasn’t happened for a long time, technology improves.

If it was recorded today they wouldn’t be removing mains noise from the recording.

Believe that your magic cables and adaptors actually make a difference but until you actually provide readings that prove this I’ll just continue to believe you’re delusional.

Strong views are fine, but being so certain when you've never tried any of these things, that's delusional.

And those cables and plug in adapters can make significant differences, the improvements take sometimes only seconds to realise especially on the passive filters that be enabled / disabled with audio playing.

We are trying to get a listening session organised from this forum, however there was not much interest. I'm happy to bring all these products to demonstrate, I can back up everything I've ever said.
 
Jason makes a good point about a testing session.

I offered this a few months ago with the opportunity to have a coffee, listen to some music and compare a few tweaks to see if anyone can discern a difference.

There are several people happy to state that no difference is possible. Are they all just internet keyboard protagonists?
How about actually having a listen. The aim is to have a chilled session, not result in swords at dawn.

Any takers?

If they make significant differences then they would be affecting the signal output, which would be recorded on a meter, yet I’ve never seen a company show scientific readings, why is that?

Listening sessions won’t prove anything. In double blind tests you’ll get people adamant that something sounds better when in fact nothing has actually changed, just because they are expecting a change.

Sounds like best way is to not chamge anything and see if people think it sounds better. Most of the audio world seems to sell stuff based on placebo.

As long as it's viable, happy to conduct the test however you wish.
When do you fancy?

In this thread there is a youtuber who has tested passive mains conditioners with test equipment, showing differences in actual amplifier speaker output.
