  So what's the problem ... what do you want to achieve??
  
  Your original post said you used some of the "chalk ones" (white rectangular resistors? - if so, they should have an ohm value written on them) which you had laying around ... but you're not crazy about the sound of your 1.6s.
  
  Do you therefore want to tone the treble down more (than what the wire jumper delivers)? Or what?

    lets get the obvious out of the way first
    
    1- No room treatment at all-Its my next project behind setting up my listening room around my acoustat monitor 3's
    
    2- Adcom GFA-545 Amp-not my favorite...Ive auditioned an anthem mca 5 that I hope to get soon.
    
    3- Small Square Room with Tall Ceilings- the room is not the best size
    
    4- I expect at some point to work on the guts so to speak- crossover, fuse bypass, myestands,ect
    
    So with that said I dont expect attenuators or jumpers to make a significant change, the purpose of the thread was to assess what are my options based on the stage Im at currently.
    
    The problems Im having in terms of sound quality with the 1.6's and the mgcc3 is brightness. Ear fatigue sets in after only an hour or so of medium level listening. This particular room is my personal space which is used for tv, movies, and music. Im using an Arcam AVR 350 and an OPPO BDP83-SE with a powered Klipsch sub. The center channel has a really low level of sound with it turned up all the way in the speakers trim section.

      That is absolutely no good at all, mate. I can listen to my true-ribbon Maggies for hours at a time with absolutely no fatigue ... unfortunately, though, I rarely get many consecutive hours of uninterrupted listening time!! :-((

      Now, some people love the sound of the 1.6 and some people don't - just like with true-ribbon Maggies. :-)) From what you've said, I suggest that until you get "stuck into them" (ie. "work on the guts"), you need to attenuate the QR with a resistor.

      Of course, if you change amps this "brightness" (read "harsh"! :-)) ) might go away but, in the meantime, you need to do something.

      You appear to have tried a stock Magnepan sand-cast resistor (which you said didn't sound too good! :-)) ). You didn't say what value this was but I suggest you do what neo suggested - ie. buy some pairs of 12w Mills wirewound resistors in, say, the following values:
      0.75ohm
      1.0ohm
      1.25ohm &
      1.5ohm.

      Then buy a pair of Duelunds of the value you like best.

      You might also be suffering from RF interference. IE. use a choke instead of a wire link and get a pair of the chokes which Al Sekela recommends (various inmates use these, so they should be able to tell you what to buy).

      Enough inmates love the sound of their 1.6s to "prove" to you that they can sound nice - your problem is simply to make this happen.

      Regards,

      Andy
