I have an Onkyo HT-R410 receiver, which I had hooked up with 16 gauge wire to vintage Sansui SP5500X Speakers. With the receiver on and no source, the Sansui Speakers exhibit white noise, which becomes increasingly more noticeable as I increase the volume. The speakers begin hiss and pop if I increase the volume past 50 on the receiver. The speakers have max power rating of 120w at 8 ohms, while the receiver is rated at 100w RMS at 8 ohms. What I would like to know is the following: Is there a way to eliminate the white noise; why is the popping occurring? Thanks, Jonathan.
