Even after auditioning 3 separate AVR's, the same ambient sound of the room was still present! That told me the unwanted faint background signal noise I had been experiencing had nothing to do with the actual units. Therefore, my attention changed to the cables. And even then It was only on the third occasion after I finally purchased shielded cables that the noise floor within my small room finally came down to satisfactory levels. Unshielded cables often act as antennas for attracting RF, and the longer the cable, the better the antenna. Probably explains why when I used to disconnect my heights and surrounds within 10 minutes, the faint background signal noise (RF/EMI) within my small room used to disappear/dissipate. The more cables I shield, the quieter my room becomes. In fact, the last group of cables I shielded were my HDMI's, and Lo behold the room became slightly quieter yet again. When friends came around, I used to show them how loud the system goes. Now I prefer to press pause and show them how quiet it goes. None of them gets it, of course 😂
