I would like to rewire my TS-1's with higher quality Cardas wire. My question is, I unscrewed the binding posts and driver, and noticed that the internal wires are not soldered directly to the posts/driver, but have crimp-on connectors that are then screwed down onto the posts/driver. Should I use the same technique on the Cardas wire, or can I safely solder the wire directly to the posts/driver? Seems to me like a soldered connection would be better than a screw-on/crimp connection... but I realize the Fostex driver is a fragile one, and I'm not sure if the heat from a soldering iron would permanently damage the driver. I'm less concerned about the binding posts... any advice or information would be much appreciated.
