This is a phenomenon that occurs with most power amps or audio equipment that have large capacitor banks.You will also notice that this "twang" does *not* always occur at power up. It depends where on the 50/60 Hz AC signal the power switch makes contact. If it's near the peak of the signal (positive or negative), you will hear the "twang," if it's near the zero-crossing part of the signal, you will *not* hear it.
