your talking me into it,,

will to bypass the right side and listen for the differences,,

I'll report my findings after several days listening,,

thanks all

well that took less than five minutes of listening to convince me,, both speaker fuses are now bypassed,,

played a Linda Ronstadt & Dolly Parton vocal with only the right speaker fuse bypassed and could hear the difference between them immediately,, thought it may be an error as my hearing drops off in the high 12K area but after moving back and forth four times there was a difference,, highs are certainly smoother for my ears,, just offered cleaner and improved sound,,

thanks for the easy arm twisting to convince me,,

  Dare I say that the highs are more "ribbon like" without the ribbon resonances that sometimes can be heard. Next up, find the value of the iron core inductor on the bottom end planar and replace it with an equivalent air core type. Surely someone here knows the value, or you can check with Magnapan. The differences you will hear will be on the same scale.

    Careful with a new inductor. Lower DCR, from the stock 0.4ohms will change the crossover frequency. Personally, I'd not do that without more knowledge.
    
    Someone out there with simulation software or who can 'do the math' may want to comment on this.
    
    That being said, the main advantage of an aircore are 2x. Higher current capacity and it won't saturate at higher powers.
    
    Also, if you consult some of the inductor design calculators, you can design an inductor with the same number of layers as turns per layer. This makes a perfect 'square' cross section inductor. Going thru several iterations, I managed to get to 0.38ohms using 13ga wire....If I remember correctly. This is the one I'd build or have built. Pot it in epoxy and give it a couple hours in the oven and you should be golden. I preheat to the lowest temp, shut it off and let it be. I did something similar to slot car armatures back in the day.

      ...previous post where I stated: �This past week I�ve removed the fuses on my 1.6 � everything within the soundstage seems to be better defined� this is indeed quite true however the fuse bypass can�t be credited ... let me explain.
      
      On Saturday finally opened the connection plates to bypass fuses � to my surprise the fuses had been already bypassed albeit slightly different configuration that I'm still not comprehending fully ( see link below ) - regardless I�ve been fuseless over two years - Placebo at its best? At the time fuses were removed from the holders major tweaking was performed on speaker/chair placement � the critical/controversial tweak was perhaps going from a 3� back tilt to a 5� forward tilt plus chair fussing - the improvement in sound as described arrives from placement - the fuse tweak in this case was a given but was never told ☺

        The forward tilt is also recommended by Jim Smith in his book Get Better Sound . It work's for me. I'm a big fan of Jim's approach to setup. Have you read his book?

        Jim�s book was prime motivator in aligning center of panels to seat height.
