Amp/Int. Amp to smooth the highs...

...okay, so here is the story...i just purchased a pair of great sounding speakers...i placed them in my rig and they do everything amazingly well, but the top tend to be a little bit screechy (i can live with it, but maybe can be fixed) from time to tome...well, my preamp/amp are not screechy as they proved with the old speakers...so, me thinks i might need another amp or int. amp to replace the amp and the preamp to "mellow"a little bit hte highs but still with great bass, soundstage, midrange, etc...is anything out there?...my current system Audiomeca Keops, Innersound preamp, Innersound ESL amp, and Innersound Isis just replaced by Usher 719xspeakers...

thanx

Oops Iasi- I read too quickly and incorrectly assumed you had innersound speakers. If these are brand new Ushers then lack of break in could very well be your problem.

Gunbei -

Paralleling the tweeter with a fairly large resistor will actually lower the impedance that the amp sees, and will also smooth the impedance out out a bit.

I got better sound when power is around 150 W or above (SS amp). Yes, it took me almost 100 hours for breaking-in.

Thanks Duke, I'll do some experimenting.

Adding a resistor may cause additional problems. People at Madisound know a lot about this subject but I think a resistor will change the crossover frequency. It can also cause phase distortions unless you add an inductor in parallel with the resistor.
This is from memory and while maybe not completely technically accurate you get the idea.

How about AIG imagers from www.audio-ideas.com?

Or just stick a felt ring around the tweeter?
