I just re-wired my vintage B&W DM7MkII's. Wow, what a difference! The internals were all cheesy aluminum cables w/ spring-type wire terminals. I used wire that matched my speaker cables exactly, same brand/type. For the Molex connector to the crossover, I used WBT silver solder and gold Molex inserts... all soldered. The original harness was all just aluminum crimped inserts. Updated with some nice Cardas copper binding posts & custom fabricated plates. Some plasti-clay in some cabinet holes & voids and to keep wires from vibrating on any internals.
The bass is noticeably faster, more accurate and fuller. I did one speaker first just to compare. Everything is tighter and more focused. An amazing improvement for less than $100 in materials for an already great speaker.
I don't understand how some folks will spend $$$ on cabling only to be bottle-necked just past the connector in the actual component. Especially high $$$ power cables... there's usually that poor connection at the fuse.
Anyone else out there have experience with a project like this, good or bad?
