I hadn't seen the K701 (or most AKGs) mentioned in this thread.... so just throwing them out there too.

Yes, its only luck all my stuff plugs in on the left of my body. Some of the point of single-sided cable is lost if its travelling across your body.

As a point of interest, electrons move (in copper) at a rate of something like 1 meter per 11 minutes or something. Just thought I'd share

Is there a reason Larry of Headphile changes DBs to double-sided cables?

Yeah but theres |---------------------------------------------| this many electrons, so they dont have to move very fast.

Yeah right.

Here's a 2 meter long bare-ended copper wire for you to hold onto. Now I'm going to plug the other end into the wall outlet - hey, no worries mate, as long as you stop holding it within 20 minutes, you're safe.

He's right though, the actual electrons move down the wire slow as molasses

Incorrect. Electrons do not move at the speed of light.


In fact, they move at speeds on the order of millimeters per second. It's the energy that "moves" (actually, transferred) fast through a wire. But even that doesn't travel at the speed of light. It varies with the material of the wire.

Think of it like this:

- A tube filled with goo.
- You push on the goo from one end.
- Goo from the other end comes out almost immediately.
- But has the goo particles you pushed on the first end moved to the other end in that time?

Ultrasones generally employ a single left-side cable with the exception of the iCans and the expensive Edition series which use dual-entry cable.

As someone already mentioned, in the AKGs the steal headband itself is the wire to the right channel. It's a big solid core, so it suffers from the skin effect at the higher frequencies. At 20kHz the band itself may add up to 20 ohms (or more) to the right channel. So if you're recabling the K701s to balanced, a standard Y-shaped cable would be better.

So I've now recabled my Grado Sr225s to one-sided; and they sound just the same. Smashing

In fact, I've put stereo sockets in the bottom of both earcups and wired so that I can plug in the cable to either cup and have stereo sound! They're definitely more comfortable now, that chunky Y-piece could really annoy me.

I once reported about the K701 phones utilizing the steel headband to conduct the signal to the RH earpiece.

Skin effect in electrical conduction is not significant at Audio Frequencies - it is a Radio Frequency phenomenon.

In the real world using the steel over such a short distance is of no significance other than being a 'fashion over function' abuse of the purists approach to electronics.

that's not what the measurements say... at 20kHz the effect is already quite significant...

 

[jirams]

which measurements and by whom ??
