How can the Grado extension cable cause a buzzing?

Recommended Posts

So I'm listening to a record, and on a whim I plugged up my Grado 15ft extension cable to give my RS-1 a little room to move (damn Grado stock cable is too damn short damn it).

At the end of the side, I stand up to flip the record, and notice a buzzing noise coming through the headphones that was previously undetectable when the music was playing. I unplugged the Grado extension cable (because I've always been suspicious of it) and just plugged my headphones straight into the amp. The buzz goes away completely!

My question: how can a cable be so crappy that it actually introduces noise into the system?

The extra cable length is giving the signal more room to develop and therefore allowing you to hear things the stock length is too short to reproduce. It's all to do with the wavelengths involved at the buzz frequency. I'll wager the buzz is pretty low thus validating my claims because low frequencies are longer and need more wire or the signal wont fit.

Or it could be a minor short/bad ground connection.

I just did a test based on this theory. When I plug in my RS-1s without the extension cable, with none of my sources on, and I crank the volume all the way up to the max, I do hear the faintest of a buzzing noise. So it sounds like yes, the extra cable length is actually giving the signal more room to develop, therefore I am noticing this buzzing noise inbetween songs when at a normal listening level when using the extension. I notice this buzzing to a lesser extent when I plug in my GS1000, which is recabled with 10 ft Black Dragon, and again crank the volume to the max with no source on.

Since the buzzing isn't source, can, or cable dependent, it must be something emanating from deep within my amp. The amp is a Veda Audio Dynahi SA. Its a badass amp but its bootleg as hell.

Thanks Smeggs!

Does the problem occur with other amps???

I don't want to start an argument on my 2nd day here, but what you say above is not right. Low freqs do not need certain minimum lengths of wire to develop or fit. You are confusing acoustic waves and electrical signals.

This clearly explains why a Senn 650 which has a 10' cable has more bass than my Grados which have 6.5' cables. It's so obvious now that I think of it. ;D

OMG, roflcopters!!!1!!111

I'm sorry guys, I was in fact making the whole thing up parodying the whole cable BS theories from H-F and writing something totally implausible but in a sorta pseudo-believable way. I really don't know shit about this stuff and was being totally facetious. I'd hate to actually be correct in any way based on a joke because it's just too retarded to contemplate ;D

I actually think Posty is pulling my leg in return >:D

I know, I know, at my age I should be less of a fucktard. In my defense I have the mental age of a 15 year-old which is why I'm a game developer instead of having a real job :D

No, I was referring to the lashes, not the leg-pulling. The leg-pulling I quite enjoyed ;D. Everyone should act like a 15yo at least a couple times/day.
