I've had everything running most of the weekend and everything looks great, although I've only been listening to tv so I haven't been pushing them. It is sitting inside a glass enclosed cabinet and is running warm but not hot, so I don't see any reason the Onkyo 607 couldn't handle higher levels without issue.

Just some negatives, mostly just nit picking on my part so it should detract anyone from this unit...

1. I like the front displays better on the Denon's and Harman Kardon's. The Onkyo's just seem very simple.

2. There isn't an external 120v outlet on the back of the Onkyo. I had one on my HK so I could run an external fan to keep it cool. It would be really nice to have that so when I turn the receiver on, it also turns the fan on. I have to figure something out there.

3. The OSD only works through an HDMI connection. This seems odd not to be able to do through a component or composite connection. Without hdmi, the setup has to be done thru the front display screen. This will only be annoying until I get the new tv and PS3 into the setup.

4. I'd swear the Onkyo sounds a little brighter than the HK I replaced. I have the crossover settings the same as before and could swear it sounds slightly different. Maybe it's just my imagination.

Can someone explain this setting on the Onkyo? The LPF of LFE setting? It can be set to 80hz, 90hz, 100hz or 120hz. What exactly is the purpose and what would the ideal setting be? I haven't seen this type of setting on the Denon's and HK's.

How well was the 607 able to handle the M80s?

Shag, that LPF is the low pass filter which affects only the channel which carries the low frequency effects which are occasionally present during movies. It has nothing to do with the bass redirected to the sub from speakers with a crossover rather than full range. The LFE channel theoretically extends as high as 120Hz, but in practice little or nothing is there above about 80Hz and most is much lower.

Some suggest that the full 120Hz setting be used, in case something useful might be there in some cases; others suggest setting it at 80Hz to lessen some 120Hz hum or other noise that might be up there. It doesn't appear to be a crucial point either way, but I'd be inclined to set it at 80Hz.

Just a suggestion for that, but I use these nifty remote switches for that purpose. It does add another remote to the setup though. I have heard there are more advanced models that can be powered on through a Harmony remote, but I never bothered looking into it. Anyhow, if you you put the receiver, fan, and anything else specific to receiver on the same surge protector connected to the remote outlet, problem solved perhaps.

I just finished my second cup of coffee. Thus, I also just remembered that there are "intelligent" powerstrips, which is another solution I was looking into. With these powerstrips, there is a master outlet that dictates if the others are powered. So that if your receiver is plugged into the master outlet and turned on, then the other outlets on the powerstrip will also receive power. However, if you turn off the receiver then power to the other outlets on the strip is killed (and then the fan, etc, is turned off with the receiver or on with the receiver).

That's some intelligent design I can get behind.

Shag I am very interested in how the 80s and the Onkyo 607 work. I am seriously looking at the Onkyo tx-nr 906 and the Epic 80-500 for my setup. I am waiting for a reply from Onkyo tech support to confirm that running 4 ohm speakers would in no way effect my warranty. The plan at this point is to order the Epic 80-500 the last week of May from Axion FO. my wife will be out of town the last week of June so it would be a perfect time to setup and new system and tweak to my hearts delight.

Everything seems to running just fine although the TX-SR607 is running a little hotter than I first stated. It keeps the whole cabinet warm. The PS3 also runs warm so when I introduce it into the cabinet as well, I would expect to find a way to keep things well ventilated just to avoid any other issues. If your equipment isn't in an enclosed cabinet, it won't be a problem.

The manual says the 607 has a setting for 4ohms and 6 ohms.



The "Note" probably explains why I can't find that settings in the setup screens.

Leave it on 6, no matter what. 4 just limits the current and may cause clipping.

Thanks for all the replies. I think I'm going to order the 2 M80s, 2 QS8s, and the VP150 next week or shortly thereafter. Rather than spending extra on a custom finish, I'll get black oak (maybe Boston cherry) for now and I'll be a snob about the finish when I have more money to throw at a home theatre system. Won't be able to post my impression of the speakers until after the week of June 15th (when I get into my house).
