My main question is how well do the pre outs work on Onkyo receivers. I've read that some other receivers equipped w/ pre outs do not work well or have issues due to not having enough voltage to the outs. I'm not necessarily concerned w/ using the receiver (Onkyo 707) as a pre/pro. At most I would use an external amp(s) from the front L/C/R.



It's almost time to upgrade to a new receiver. My old Pioneer has just about had it. I almost pulled the trigger on the Onkyo HT-RC160 earlier today. It has a really nice feature set, but I'm a bit worried about the watts per channel rating. I'm concerned that with driving all 5 channels, it's going knock the wattage per channel down to 40 or less.


I'm not really all that concerned with that issue for watching movies, but I do listen to a lot of music and I do tend to listen at high decibel volumes, so I would like to have a lot of clean power on tap for at least the front 2/3 channels.


The new Onkyo SR-TX707 should be hitting stores soon and the specs say that it will have pre outs for all 7.2 channels and I'm guessing that it will be in the $500 to $600 range, which will work out perfectly for me.

I use an Onkyo 805 as a pre/pro with a Sunfire Cinema Grand 200x5 amp in my family room, and an Onkyo 876 as a pre/pro with a Sunfire Signature Seven 400x7 amp in my theater room setup. Both amps are set for signal-level power on, and I've never had a problem with either setup.

Awesome! That's exactly what I was hoping to hear! Now to start shopping for power amps in my budget!

I have pre-amped out my 805 to 7 Outlaw 2200 monoblocks for 2 years without any problems at all.

Is it night and day different with the separate amps vs the Onkyo 805 built in amps?

That's a difficult question to answer. My "night and day" may be totally undetectable to someone else. However, I got the Cinema Grand first, and obviously I thought it was "night and day" enough to snag the Signature Seven. I think a lot of it depends on your expectations, as well as what speakers you use. I have Definitive Technology systems in both of my setups (see my profile), which range in efficiency from about 88-91dB, so pretty much anything will drive them. However, with more power, they just seem to open up more, and simply have more presence throughout the range. Additionally, I run my theater at reference levels much of the time, and with the dynamics that a lot of BD's and HD-DVD's reveal, I never really have to worry about having the headroom in my amp to handle the peaks. Lastly, it decreases the load on the receiver itself, which I use to power a second zone in both setups (one upstairs and one downstairs). So for me, it was a worthwhile enough investment to go with outboard amps.

Not in any properly controlled test!


Anyone posting differently is full of subjectivity and tend to exaggerate because they do not do the right tests.

Budget Onkyos consistently bench test at 80+WPC with 5 channels driven.
