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

Masters of smoothness in my experience are McIntosh amps. I looked a long time for that smoothness and Mc gives it to me in spades. I can listen all day with constant goose-bumps. love it! The highs are as nice as I have ever heard (except for Pass X350 and Lamm M1.1). Anyway, good luck -Arthur

Duke, your suggestion is very interesting to me, maybe something I'd like to try. Will wiring a 16-ohm, 25-watt resistor across the high frequency inputs result in the amp seeing a higher impedance for the tweeter?

Duke,

Thanx for the imput...i have to try that...i know is not amplifier clippin since the InnerSound ESL was used to drive the Isis (a more demanding speaker) with no problem what-so-ever...if you wanna find out more about the 719's go on the www.useraudio.com and look at Compass Series for the top model monitor...
i'll try some different speaker cables as well...as i said, the problem is not that bad...in only certain passages i can detect a little bit of "metallic"sound...

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.
