Yes Course I think thats were thier cables make the most improvment in sound.

 

Just thought you may have some others on the dvd and dacs. 

 

Have you tried Clearer Audio?

I have ordered an upgrage for mains of my Audiolab M-dac.... The oppo 105 is very particular able mains cables... It seems not to like them for some reason.. The original cable with the oppo 105 sounded much better.

Anyone searching for an example of expectation bias need look no further than this thread.  

In a past life I designed audio recording equipment for a well known national broadcaster.  At no stage did we entertain any cable tomfoolery, except to specify current carrying capability for mains cables, and basic LCR parameters for signal and speaker leads.

In spite of this, we still managed to build studios which arguably produced some of the best recordings of the 20th century. Just remarkable how we managed to get by without the benefit of modern marketing.....     

 

Absolutely, there was someone earlier that seemed to think paying £80 for 2 bottles of wine was an excellent way of spending that sum.  Now that really is 'expectation bias'.   :O

Hum... What of ..WIFI.. internet.. sky.. virgin satellite...  not to talk of more equipment in ever house. In one home you may have as much as four laptops or even more phones. The noise in the mains these days will not be the same like the time you mentioned.. I think you need to kind of bear that in mind..

Strangely, in the 30 years since I was an EE, the basic theories of electromagetic radiation and conduction have remained the same.  In fact, they haven't really changed for the last 100 years.  

As long as your amp has some filtering on the mains input (a power supply transformer and storage caps make a pretty good filter), then no amount of nonsense with a mains cable will make any difference.

If (and it is a big 'if') your amp has an extremely poorly designed power supply, and your mains is extremely noisy, then a proper LC mains filter placed close to the amp may make an improvement, but not a magic cable.

While there is a tendency on this website to dismiss expectation bias effects as 'it doesn't happen to me', given the lack of any scientific underpinning for mains cable claims, and the wealth of reports on the unreliability of human perception, my money would be that any difference you hear is not due to the cable.

I only buy when i hear a difference in sound.. I am very good exmaple of who do does not listen to what people say but what my ears tell me.. One thing people forget as well, you can never tell if you listening is the same as mine or any bodies for that matter. If you have tried this particular wireworld cables & cnt hear any change in sound... that sounds sad to me.. Cause its giving me much more listening pleasure.

Undoubtedly but someone will probably bring out an "audio-grade" inverter!

RE: Mains cables ?

hi all,just a thought if mr poster of this forum tries out his 40/80 pound cable and reports back and says that it did make an improvement in his system,will he be talking rubbish as well, or for the none believer,could there be something in this mains cable debate that people do  hear or see a diffrence,and if it dose'nt work he should give up or try a diffrent cable, i think a mains cable is as important  part in the hifi chain and should not be ignored.cheers david

Don't knock the oenophiles; we really do know what we're talking about (and can prove it through blind tastings).

Do a blind comparison. If you can see which cable is being used then it's all to easy to convince yourself that you can hear a difference when there isn't really any difference.

I generate my own electricity by running an audiophile grade electric generator that burns methane produced from cow manure.

 

The improvement to the sound quality of any hifi system running on this hifi quality electricity has to be herd to be believed. :shifty:

I've heard that using cow manure gives muddy bass.
