Spent some time recabling this weekend. Sorted out both my K81DJ and SR-60s. The K81 I did to help reduce some of the bloominess in the bass and hopefully bring the midrange forward a bit.

24 awg stranded silver wire in a litz braid covered in heat shrink and connected to a 1/4" adaptor I bought in bulk off ebay:






I used Canare mini starquad on the Grados to tame some of the borderline harshness and help warm up the already beautiful midrange. As I'm an OSU alumn I decided to use some orange tech-flex over the black wire. It's a little stiff but not unbearable:





With the AKGs I do notice the bass energy better contained and what I considered a muffled mid-range has been brightened a bit.

I'm extremely happy with the result with the Grados: the harshness in the upper range is more subdued and I find the listening experience as a whole to be much more enjoyable. I will say, though, that separating the Grado cups was a HUGE pain.

It's touching how American neoconservatives, who have no regard for international law when they want to invade some troublesome country, have developed a sudden reverence for national sovereignty.

Apparently, context is everything.

I just finished making some cables for my $99 Musician's Friend 1212m. Now hopefully UPS delivers the card tomorrow so I can listen to them.

  • 1/4" Switchcraft Plugs
  • Canare F9 RCA Plugs
  • 20 gauge Teflon coated silver wire
  • PTFE Teflon heatshrink for outer cover
  • Regular heatshrink for left/right designation.

The Teflon heat shrink was a pain to work with because it doesn't shrink untill about 650°F. Even with a heat gun and a directional tip, it took a long time to heat the stuff up to shrink.

hey guys, sorry to ask a noob question, but what is an RCA to Mini connector actually used for? My knowledge is extremely limited, obviously.

Depends on your situation, but for me it's to connect my Ipod (or other portable) to an amp with only RCA inputs. My first IC was a female stereo mini -> two rca plugs to connect my Ipod to my desktop PIMETA.

Here are some new ones hot off the bench.

First up, a 75ohm digital cable for connecting my CD player direct to my CD recorder:



Recipe: VHAudio cryo'ed Pulsar cable - copper center conductor, Teflon dielectric, fine silver plated shield; cryo'ed Canare 75ohm RCAs

Second, an RCA to mini-phono cable for connecting my wife's iPod to our stereo system:

I did this recable job (on my old set of AIWA cans) about 6 months ago. Credits to AK[Zip] for giving me some basic primers prior to my starting the recable job.

Modifications:
- 22awg SPC wires
- PVC tube sleeving for the main lengths
- PET sleeving (techflex) for the splits to the drivers
- Dual-entry cable (they were originally single-entry)





Further 'modifications' to each side of the drivers:
- Custom-cut set of foams (original ones were too flattened and it was affecting comfort & sound, negatively)
- Defoaming of the drivers
- Application of Blutac to interior of the cups (no pics unfortunately)


The only thing left to do is the headband. The vinyl (or whatever) layers are flaking away badly. Despite my effort to remove them, much still remains. A Beyerdynamic-style headband would be nice but I'm not sure where to find them here.

Cheers!
