RE: Easy Magnepan MMG tweaks?

You can bypass the fuse and fuseholder entirely by removing the binding post panel and switching a few wires around - no soldering required, just a crescent wrench, screwdriver and pliers. Take a photo of the back of the panel before you move anything and draw a wiring diagram. You just have to move one wire from one side of the fuseholder to the other to bypass it. I wouldn't do this while the speaker is under warranty though. My SMGcs are 17 years old so I can afford to take chances. They've been fuseless for several years now with no problems.
If you're using the 1 ohm resistor, you may not notice an improvement by bypassing the fuse, but it is something you can try and put it back to the original configuration if you don't like it, no soldering or cutting wires is needed.
I used to use the resistor on my SMGc's, but I removed it when I switched from a Hafler DH200 amp to a Linn LK280. With the Linn amp the highs were cleaner (less distortion probably) and taking the resistor out sounded better, with more extended highs but it still didn't sound overly bright, just more extended.
I'm posting this from Hawaii (Kailua) while at my dad's place. My wife and I may possibly move out here (from Texas) sometime in the future, the threat of corrosion would probably cause me not bring out the speakers but revert to a headphone only system (much lower shipping cost too.)
What part of HI are you living in? Windward or Leeward side? I think corrosion is worse on the windward side.
