HELP-Maggie IIIa's are crackling at high frequency

I have newly refurbished IIIa's. The refurbishing was done by a trusted third party tech. I noticed the high frequency once before when using my Nuera 3300pp integrated but only on ONE record so I chocked it up as a flaw in the record. But just this weekend I went up to a AR V70 power amp and an AR SP-6b pre and its more prevalent than ever. I am not a "loud" listener and I here this "crackling" on the high end of classical female vocalists the most. I have read that people push the maggies as far as to blow the fuses before they get any distortion. This amp combo sounds like it would blow me away but I can't hear past the distortion! Any advice would be awesome and much appreciated, Thank you.

Sonorous, have you isolated the problem to possible clipping? If not, what have you come up with?

Good luck.

Bifwynne,
The amp is definitely clipping. The speakers are in beautiful shape. So now I am trying to find a speaker that will best compliment my amp and preamp. I would really hate to change them at this stage. I went through a lot of trouble finding them and having them professionally gone through, let alone the time and money spent selecting tubes. The issue I am having is with the 10% percent of my music collection that is classical/opera with wide dynamic range and sustained high frequencies that easily make the amp clip. The Jazz sounds wonderful.

So now I posted a new thread to pick even more brains as to what speakers I can fuse with my amp combo and not clip the amp (if any at all) or anything else I can do to my large listening room that will make it so I needn't ask the amp for more power.

Maybe I am asking too much from one system?

Thanks for the advice thus far, learning as I go!

How bout
a pair Vandersteen X5 High pass units and a pair of Vandersteen 2WQs
this will ease the load on your main amp lower distortion
improve dynamics dramatically improving clarity and transparency of the
whole system while also retaining the intimacy you like
with your existing amp
