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.

A good class D power amp of same or higher power would probably fix the problem.

A cheaper thing to try beforehand might be to swap in a pair of inexpensive MIT Terminator ICs for the Monsters and see if that helps. If not, probably still a good investment down the road.
Has anyone tried Sound Anchor stands on the 1.7's or similar? Any difference in overall sound?
solution: sell me your speakers for a great price!
check the date of build on your speakers. i was told by a dealer that there were problems with his original 2011 1.7 demos, but no problems with subsequent sales w/newer panels. i imagine he sold the demos off slightly cheaper & replaced them with ones of 6/2011 vintage. he didn't know if others were lemons but he wasn't happy with his demo-obviously, his customers still ordered 1.7's. hmmm-maybe our ears aren't really that well trained as we think when hearing such well-reviewed/well thought of speakers??? most surprising to me was deciding not to return the demos to magnepan with his complaints?
by the way after hearing the 1.7's twice i longed for my just sold IIIa's. also, i too find the 1.7's bright. owners can cap the highs down w/provided resistors, tho it seems like you're defeating the exquisite highs maggies are known to reproduce. personally, i've decided i'm buying 3.7's.
I have Maggie 1.7 and Cary tube amp. Definitely sounds too bright. Cheapest solution is to buy Mills resistors at parts express. I bought 0.5,1,2 ohm values which gave me ability to fine tune from 0.5 to 3.5 in half ohm incremental steps. To my taste(and my system)2ohm worked the best. transparency and details retained while tweeter was tamed to perfection giving integral nice tubey sound. Cost 4$ per resistor saves thousands instead of changing DACS, preamps and tubes. Highly recommended! And yes Maggies need 4 tubes per channel to sound good.
