I just bought a brand new Marantz NR1603 and brand new floorstanding speakers (Q-Acoustics 2050i). After wiring everything up I started playing some music and it all seemed pretty great. However, one day later, I started noting some white noise in the mix. Usually, I am sitting about 3 m away from the speakers and during somewhat quieter parts in a tune, I can hear the white noise. If I move closer to the speakers its quite audible. The white noise is definitely coming from the tweeters.
I know that some white noise is expected, but I thought you would hear that only if you have your ears very close to the speaker. As I said I can hear it sometimes from a 3m distance. Does anyone here have any clue whether this is normal and what could be the cause of this?
The Marantz AVS has an output of 50W at 8ohm and 80W at 6ohm per channel according to the spec. The speakers have a nominal impedance of 6ohm with a minimum of 4ohm. I don't think this will be an issue right?
Secondly, the speakers are not yet bi-wired. Would it perhaps help if I bi-wired them?
I played my music so far only with the volume at 65%, so I have definitely not damaged any parts by cranking the volume to high. I placed my AVS in a tv closet (with enough room to be cooled sufficiently though) with a bunch of other equipment (modem, blu ray player, satalite box, NAS). So there are quite a lot of electrical cables. However, I already disconnected all other devices (except the blu ray as it plays my CD's) and the white noise persists. So I guess the current in the electric cables interfering with the AVS signal can be ruled out.
Any other Ideas?
