What amp to tame Eggleston Works Esotar Tweeters?

My speakers are Eggleston Works Andra ll and Andra center. My rears and sides are also EW. My processor and amp are Lexicon MC12B and LX-7 (made by Crown). 99% theater use in a 7.1 system. Left speaker 25', center 17' and right is 10'. My room is fully treated.

The problem is the Eggleston Works speaker Esotar tweeter are very revealing and I am sure the Lexicon amp is not helping any either. My ears are very sensitive to high frequency sound such as edgy treble.

I may change out the LX-7 amp for an Ayre 7xe, Mcintosh or a Sanders ESL, Classe or Rogue Audio Medusa amp... to also help smooth/warm up the sound a bit. Feel free to comment on which amp I should go with or others not listed.

My speaker wire is: xlr JPS Aluminata and Super Conductor 3 with Aluminata power cords. My line conditioner is a Furman It-Ref 20 i.

Thanks.

I don't think Lexicon is all that, especially if they can make an Esotar tweeter sound bad. Remember, they're the guys who rebadged and repackaged a stock Oppo Blu-ray player and charged triple the price. I've personally never found their units to perform up to the asking price. Reputations can be persistent.

Borrow a different pre-pro and amplifier and see what you get. I haven't heard *your* Crown-sourced amp, but they too can be edgy and clinical.

I had the Eggleston Rosa with that same tweeter. Pass amps work well with Eggleston. I don't think it is a problem with your electronics. I would experiment with first reflection points and speaker positioning - width and toe-in/out. I suggest reading Jim Smith's "Get Better Sound". There is nothing edgy with those tweeters, IMO.

why not go to the source and ask Jim Thompson at Eggleston

Just bumped into it this/my old thread again from years ago. My all McIntosh system MX160, MC303, MC207 and MC152 has made my EW system sound beautiful. No edge whatsoever. The Crown amp was the likely culprit.

If that is the same tweeter that was used in the Merlin speakers I don't think you can " tame " it.....pretty annoying sound.
