Magnepan 1.7 too bright, HELP


I just bought a used 6 month old Magnepan 1.7 and hooked them to my old system, which consists on a Deonon 2900 Universal player, Emotiva USP Preamp and Rotel 1080 power amp and use anticables for speaker connections, and monster cables for interconnects.

The sound is too bright for me, I used the provide 1 ohm resisters, still too bright, any recommendations.

Wow, I don't agree with any of these suggestions, and that's odd on A'gon. Your amp is bright, and not powerful enough to drive the panels. I suggest you try and find a used innersound ESL or a Wyred 4 sound 500. Also when i have heard the Emotiva gear it has sounded VERY bright.
I took me two years to get my 1.6 set up . First i hung floor to ceiling curtains behind the speakers. This helped.Next i added "superchunk" bass traps in the 4 corners. Finally a full 4" wall treatment of OC panels behind the speakers .This tamed the highs significantly.Cost me around $200 for materials .$700 w bass traps. I had the anticables at one point and found them bright.Kimber Kable hero interconnects work well.Also 12tc speaker wire from KK.
I would look at your source first,then I would dump the emotiva I had one for two weeks and sold it my old hafler sounded much better its not the maggies.Try and find a tube pre after looking at your source first.Do not bother with cables they can be changed later.I wish I had the maggies they are fantastic much better than the ones I had.
