I would compare it with buying a jacket. They are both warm enough, but one looks nicer and is more expensive. The quality is the same but you will be happier with the one that looks nicer, and therefore you will start to believe that it's the better jacket.
am sorry my friend..but this comparision wont stick on jackets..i am actually very into jackets...and i found out there ARE BIG differnences how efficient wintercoats keep the cold,wind, water out and ventilate...i have some sailers (in my friendscircle) who once in a while attend a worldwide challenge between the bigger sailships on sea...and i trust them very much when they say some coats are just better in what they need then others..and yes...u have to pay for that..
and no matter how many people tell my cables are just a bunch of placebo effects i DO believe cables make a difference in ur soundexperience..whether for for the better of for worse...i even believe in vibration feet...as i tested it rigourelously on my very microphic full tube amp, the 337...i think i tapped the poor amp a million times while trying out different kind of anti-vibration feet and other thingies...and they WORK (some of them DO..not all!!!!) with the feet i kept (almost the least expensive ones i tested!) made the amp sound like a solid block...u couldnt hear the tapping in ur music anymore...and pls dont tell me i imagined that..as if u really start that one u have to get to a loony house..as u cant block tapping noises with ur mind..if u can..then ur one of those people on that new excellent series that started: 'the tomorrow people' with their special mind powers..i love that series!!..hehehehe
and i talked with a friend of mine who installs all kind of electrical installations...(he is an engineer in electronics and some more)...and his company just finished an update on the Dutch ex-queens (Beatrix) new home security/monitoring system last year..so he knows one thing or two on how electricity and current etc. can influence monitors and listening mics etc. and how to minimize interference in the signal
he at first was just like u guys when i told him about my upgraded toxic cable and my upgraded powercables and me even connecting the powercables correctly fasewise (my powercables has a RED DOT on the life/positive wire side in the wallsocket..so i had to get a little screwdriver with a light in it that lights up to find the postive wire on the wallsocket (in europe we have shuko plus with two pins, plus and negative..so u use it both ways, 'in fase' and otherway around).
on both accounts he heard differences especially when changing the standard cable to my toxic cable...the feet were a nobrainer also...it was clear to hear...but i have to confess he had a hard time hearing any differences while alighning the fases on the powercables (i had two)..but as i once said before..my ears are very sensitive..so its possible he just didnt hear it being a huge hardcore metallica fan listening to levels i cant even imagine..hehehe
so...in short..most of my friends (who listened to my 337 rig)now are (somewhat) believers that headphone cables, (good but affordable) vibration feet on tubeamps, and in a certain extent powercables actually contribute to a better (OR WORSE) soundexperience...almost all agreed its hard to hear differences on USB cables..or nonexisting..
but as i said before...it makes no sense upgrading to expensive quality cables while using a rig thats not able to show that..some amps are only about raw power and no finesse and details or are just not good enough soundwise (like my budget mstage) to show it...with those amps its ofcourse nonsense to do that..!!
like my matrix mstage that i had...i bought my first toxic cable when i had that amp with a he300...and it almost didnt improve the sound at all!! only thing that stood out was far less microphics and looked more sexy.. i really had a hard time hearing differences in sound between the standard cable and the toxic...BUT ON THE OTHER HAND WITH MY MODDED 337 AND MY MODDED HE500 THE DIFFERENCE WAS NIGHT AND DAY changing cables..some with more impact then others...
1. biggest impact was the headphone cable (especially the balanced 8wire with seperated sleeved cables for left and right i have now)...the he500 loves balanced cabling!
2. with lesser impact..but shows differences in how the bass is delived and how lower the noise level becomes: good powercable with quality connectors
3. minimal impact..fase allighing between wallsocket and shuko plugs.. a bit more soundstage in the sound (but that can be placebo!)
4. no change at all..USB cable between my external USB amp and my laptop...but i didnt expected anything more as its only 0-1's that goes through that cable..lolz
but as always..on this point i have a VERY DIFFERENT opinion to most of u guys here on this thread..funny is that on a few other threads on which i am active in (also on other forums), that members are much open and confident in how a good cable influences the sound experience...but yes..i have to admit..they do invest more in their rig then the regular nowadays he500 owner does on this thread...an amp of 1000usd is almost considered outrageous money for a headphone amp here for a he500...on other forums/threads thats just the beginning...its considered budget model...AND no...almost no one has to much money...or are rich..some just put money aside for a while and then invest in a good amp..instead of jumping immediately on a hype wagon of budget amping...like is happening now...dont get me wrong..most of the amps mentioned are good for the money and for some the only way to listen to a wonderful headphone, like the he500 is...i respect that..but if u do have the budget..try and find out whats best for ur he500..u will be surprised how much better that he500 can sound then ur experiencing now with the right investment...
ps..dont get me wrong..I TOTALLY LOVED MY MSTAGE (version 1)...IT PUNCHED WAY ABOVE ITS PRICEPOINT.. and if u dont have an headphone who needs current and ur on a budget..then i believe that amp is a nobrainer!
