I'm considering buying an Onkyo 875, as it seems the beat the competition for that price point and way above.

I'm however a little concerned about the heating issue and audio synch issue. I've tried looking through the numerous threads for solutions, but there is so much i figured i might as well start a new thread.


I read that lowering from >6 Ohm to >4 Ohm would drastically reduce the heat, and send less power to the speakers. Is that something safe to do?

For reference, i'm using a Kplisch Quintet II 5.1 speaker set with a Synergy Sub 10 subwoofer. The speakers support 8 Ohms.


I couldn't find much about the audio synch issue. What's the deal with that?

Is it caused by sources connected to the receiver? Is it really a fault with the receiver? Are just people not setting up their receivers properly?


Is worth waiting a little bit for a new generation of receivers? Onkyo or any other brand.


Thanks,

Audio sync is a delay problem with the DSP chips in the Onkyo. It has been stated as such via email from Onkyo and measured by people on this forum. Check the various 805/875,905 threads. No cure so far. Includes 805,875,905.


You should run whatever ohm setting matches your speakers. Make sure you have enough ventilation for the unit.

The audio sync issue is a big draw back for me, as i'll be doing a lot of gaming (XBox 360 & PS3). I was really attracted by the HQV chip of the 875 though... that sucks. (cable TV).


Which receiver would you recommend then?


Thanks,

Honestly I don't know. I'm waiting to see what they do next year. They fixed the problem with hum on the 605-804 models with new ones but the new tech introduced additional problems as well, audio sync, etc. Maybe next year they will get it right. If not I think I will try something from Denon, 3808ci or 4308ci.
