I'm finished with the new project. Eichman copper plugs with Belden 89259 cable. The cable is a recommendation on a site I picked up from here. The site is written and maintained by Jon Risch. It's a wealth of info on various cable. Here's a pic of them Eichmans......Strange connectors indeed... Pic of the Eichman bulletplug Anyway....To solder these, I gave it some thought and made a jig to lay the cable in. This makes soldering much easier. It's made from a scrap piece of pine that I routed a half inch round groove in. I had to widen it slightly and if you make one, just barely widen it. Maybe by a 1/32 to start. The groove is about 3/8's of an inch deep. Then I laid a bit of oak strip on both sides to lay the cable on to hold it up. Here's a pic.. Pic of the template. I must say I was taken aback when I seen the size of the Belden cable. It's small. Very small. It's right at a quarter inch thick.. The overall project? Pic of the cables. The cables are about 26 and a half inches long. I'm using tech flex carbon color for covering the cable. My thoughts are....the bass end sounds a bit tighter but the midbass and the mids? I can definitely hear an improvement. Clarity is better and soundstage is slightly wider. This isn't a hard diy project. A bit tedious as you have to be very careful with the plugs but imho....at least for me, worth every penny.
