I like the volume control on the Rat Shack Version. I use my Ipod in the car and the volume contol is a nice feature to use! Thanks to Kramer for a great mod it helps open up a new sound for this great buy!

Hi guys,

I'm new to this forum, but have been reading a lot here lately.

I bought a KSC75 recently and after getting inspiration from this thread, went ahead and re-cabled it with ethernet cable(2 twisted pairs) and they sound incredible. I had read a lot of good about plenum(teflon covered) ethernet cable and truly it is wonderful. The bass is very tight and punchy and overall it added a lot of detail. I need to let it burn-in and see what the sound settles down to.
To sum it up, I can never go back to the original cabling - these sound so good.

Has anyone tried using ethernet wire? I know you lose portability and ease of use, but I felt it was worth the effort.

Thanks,
Ahmed.

MANZOO, could you post some pics of the ethernet mod that you did? I have been wondering what would be not too expensive but make a good improvment in terms of cable and this has me intrigued

I will take a picture today evening and post it. It does look ugly for sure .

By the way, I have the Pro4AAT , which I took apart yesterday to take a look and would like to re-wire it with a canare star-quad cable, but that's not going to happen very soon. It is a bit more effort than the KSC75 mod.

Hmm..A few reasons..

1. My Pro4AAT will look UGLY
2. Stiffness of the ethernet cable
3. The star-quad cable will be a better match for the big headphones

Goods points. Could you explain how you recabled the KSC75's with ethernet cable? Thanks

If you just leave the grills off, is that the best thing, sound-wise? Is it better than drilling holes? Is there any sonic down-side to it?

I know it leaves the driver unprotected from punctures and grunge. What might be best to protect them without sonic penalty? A piece of panty-hose? A piece of fiberglass mosquito screening?

Metal screening would protect more, but is there any downside to it? I've got some bronze porch screen laying around (real bronze, not bronze-colored other-stuff). It's stout and would protect great, but is it likely to have sonic penalties?

Guesses? Hunches? etc.

I can email pictures. I do not have access to online space to post them. I thought I could attach them to my post here.

Here's how I re-wired KSC75 using ethernet cable (2 twisted pairs). These are probably the easiest ones to re-wire. After taking out the ear clips, use your nails or a tiny screw driver to take out the cap covering the connections. Take apart the old wires and solder the new cable on both sides and you are done.

For the stereo phono plug, 2 wires(1 white each of the 2 pairs) are used for ground and one wire each of the colored is for the left and right signals. And on each of the headphone, use a white/color pair like you see.

Is this using Cat-5? If so, a question: Cat-5 has 8 wires inside, which would permit 2 wires per connection. Is it smart, dumb, or neither to use 2 wires per each of the 4 connection point (vs. only 1).

Yes, I am talking about Cat-5 cable. I used it because I just happened to have it and did not want to use a bulkier/larger diameter cable. And I think 2 pairs are sufficient in this case. Also, this is very much preferred because it will be much easier to connect and solder to the headphones. You will understand very well what I am saying if you take the headphones apart and look at how small the area is where the cables go in and get soldered.

I just pry the cover off with my fingernail.

I place my fingernail in one of the larger holes of the grille that's on the opposite side of the main square notch and pull out.

Picked up a couple of KSC75s from radio shack last week.

I got bored at work tonight and made due with what to cut out the stock protective grill to form a frame for some screening I had. I had some doubts about epoxy so I "sewed" the screen to the frame using a single strand of copper from some standed wire through holes I drilled by twisting the smallest drill bit I could find back and forth between my ringfinger and thumb. I then cut out the rest of the original grill with a razor blade. A hassle, but I had time to kill.

Sounds a ton better I think. I am going to keep one pair stock so I can do comparisons as I mod the other. I havent had a chance to do an A/B on them yet but I will.
