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

I think may be your amp doesnt have enough power to feed the speaker. If amp has enough power, tweeter wont have "si si sa sa" sound when playing music.

Thats the cause of screechy high.

Smooth is what Plinius is all about.

Iasi -

Your current speakrs are Usher 719's? I couldn't find any information on them...

Okay, you might try this: Wire a 16-ohm, 25-watt resistor across the speaker terminals (if bi-wire capable, then across the high frequency inputs). Just tighten the binding posts down on the leads of the resistor. You can vary the resistor value by ear, between maybe 8 and 100 ohms in large (50%-ish) increments. This may well smooth the highs a bit, depending on what the speaker's impedance curve is like. Without knowing the impedance curve I can't predict what the effect will be, but the InnerSound amp can drive very difficult loads so that won't be a problem.

It is unlikely that the problem is amplifier clipping - that's a very powerful amp.

If you want to address the problem by changing amplifiers then I suggest you consider tubes, perhaps Conrad-Johnson or JoLida. I'm a dealer for the latter. If you decide to stick with solid state, then try a used Pass Aleph amp of appropriate wattage. But trying a few resistors is a lot less expensive.

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?
