07 IS 250 SE 6M Noisy clutch

I've had my IS 250 for about a month now and done about 1200miles.

The clutch remains noisy
Under heavy accelleration. I could best describe the noise as a rattle reminiscent of a valve clatter or detonation, but it is not effecting power.

When I took it to the dealership, they said the new lexus has a mass damper-type clutch and that it is normal.

Any takers on answering this one. I'm inclined to be skeptical that the car should make this noise, although I drove a few test models at the dealership and they all do it....

Sounds fishy to me. Take you car back to the dealership and talk to your salesman. You spent a lot of money on a new car and I can assure you that Lexus did not design this car with a squeaky clutch. Make them fix it.
