Hi Guys,
I'm having some issues with setting up a new AV receiver in my home, i hope you can help me understand why and maybe fix it. I'll briefly sum up my history:
I was previosly living in an apartment and my setup was the Onkyo TX-SR608 receiver which powered Magnat Quantum 555 speakers (plus a center and two rears, but i'm interested in music for now). The receiver was rated at 160 W/Ch at 6 Ohms, 1 kHz, 1 Channel Driven, IEC, while the 2 standfloor speakers are 160W RMS with 4-8 ohm impedance. This setup worked very well, music was loud and distortion free even at 0db (reference level).
Recently i moved from that location to a house with a big living room. This meant a bigger tv, 4k, and of course, a new receiver. So my current setup is the Onkyo TX-NR646, rated pretty much the same at 160 W/Ch (6 Ω, 1 kHz, 1% THD, 1 Channel Driven, IEC);175 W/Ch (6 Ω, 1 kHz, 1 Channel Driven, JEITA), and of course the same speakers.
The problem is, when i raise the volume over 60 or so (out of 80max, this doesn't have thx, so no decibel reference volume), the sound becomes distorted. Receiver is set at 6 ohm (onkyo's setting for anyhing over 6ohm). I've tried this on bluetooth and airplay connections, not yet on hdmi or some other higher quality.
My question is, is this normal? Am i overpowering the speakers? Can't tell if 60 right now is higher power then 0db before, given the bigger room. Can the bluetooth/airplay cause the distortion (maybe limited on bandwidth)? Any ideeas on how to improve it? The sound pressure is pretty high, i'm not complaining, it's just that sometimes i would like a bit more.
Thanks very much for any opinions on this subject.
