So, I decided to give the RE-600 another chance after buying a new set from Sonicelectronix for a $100. I noticed that the main cable was thicker than my first set when these debuted a few years ago. Like many, I quickly grew fond of its sonic tonality. It's non-offensive, smooth yet detailed, and offered wider than average stage and depth from a small dynamic driver. However, like many who've experienced the build quality woes, such as the main cable and the TRS adapter cable were consistently subject to kinks and eventually a short where a channel would go out.
For those who owned or recall owning the infamous, yet wonderful sounding Klipsch Custom 3, which happened to be my favorite iem at the time shared the same kink prone cable as the RE-600. What makes matter worse is that these kinks are there from the factory. I opened the RE-600 upon receiving them last week and I CAREFULLY unraveled the cable and to my utter disappointment, there were four areas on the main cable section with freaking kinks. Despite sounding every bit wonderful, the unpleasant feeling of the inevitable crept in.
I had urges to fully recable them like a few members have done, but at the time the chances of destroying the delicate drivers in the process stopped me. This evening, I decided to save the RE-600 from its falling grace and out of haste, took my wire cutters and decapitated it.
Now, instead of a full recable job, I cut the cable above the Y-joint. The RE-600 sounded great out of my Z3 compact smartphone, so going forward the RE-600 had no business keeping its balanced configuration. I used three, 3 ft length 26AWG OFC wires, identified the positive channels, which happens to be the copper colored wires and strangely the grounds were the hybrid copper/silver wires. Next, I soldered the three wires to the existing wires (combined the two ground wires), used heat shrink at the soldered connections, and secured them inside a Shure-type iem shell I had lying around. It worked great despite the phallic shape and an inch of heat shrink completed the y-joint. Finally, a simple cross-over weave and finished off with a RA Neutrik TRS connector.
Here's the end result. I'm sure there are noted differences that can be detected with the appropriate equipment, or if I really analyze the sound, but the trade-off for a lighter, kink-less cable that is not destined for failure along with its TRS adapter cable (had 3 of them gone bad), it turned out to be a worthwhile project.
