Maybe on this as u call it mid-fi thread...
I had have had 6 cables until now..and on my rig u certainly hear differences in how they sounded..or better said..how they let sound through..
it was no placebo effect! Same thing could be said for the jergpads! Are those differences placebo effect? Some say it is..no matter how its meassured..
but as always..if u have a mediocre amp/dac (mid-fi..of only a few hundred usd) u wont hear any improvement on cables etc..as those cables only improve (or make worse!) the soundexperience in a small way and only if u go up in quality (am not talking about price..BUT QUALITY) u will hear differences...
as i once said..on the humble mstage i once had i almost didnt hear differences between a double helix cable and the standard silver plated copper cable..except for better quality and less microphonics and better looking..but when i went to the modified 337 with TS tubes i could hear differences very easily when changing cables..
only one cable didnt improve sound as far my experience...USB cabling...
but powercables (good ones) and headphonecables change the soundsignature for the better or for the worse... But it all depends on ur rig to let it through..
.its like a car..standard 1.1l budget cars can use premium octane 95 and 98 or even 100.. But u wont feel any change how it drives..BUT..if u change ur gas from octane 95 to 100 on a turbo charged modified engine u will see changes in how it picks up and goes through the gears and in my case i found out it drives more economical also when driving on octane 100.. (That was a huge surprise!) And thats no placebo effect as it directly affects my wallet when i drive a (at least) 280hp car.
Its same thing with amps and the rest of ur rig...if its just mediocre..no matter how good it is for the price...its just a waste of time and money to tune it more with cables etc..u wont hear it..and if u do its indeed placebo..or partly placebo... Imho ofcourse
but u know me..am like the lone ranger here on this thread the last few months
The difference between earpad modifications and different (and equally well-made) cables is incomparably huge. Earpads are to headphone drivers, as enclosure designs are to speaker drivers; meaning they are integral to the final sound signature and quality for better or worse.
People have tried measuring differences in cables objectively for audio and I think the farthest they got was some minor (sub- 1dB) broadband attenuations, mostly due to difference in cable impedance.
