Take this for what it is worth. Seems I need to do some learning on PCM.

Thanks for the info LJ. It looks like if wanting to use HDMI with HD audio one needs to be sure the receiver/processor will accept a multichannel PCM signal. It sounds like yours does. The article I posted seemed to indicate the Onkyo 05 series will not. When looking at features I don't remember anythin mentioned pertaining to PCM, what is it called on your receiver?
-
Great post L.J. !!!
Great info L.J. I very much appreciate it. Can't give you any greenies, so here's two cookies. :thumbsup:
If the lossless formats are transported via HDMI, and the HDMI spec and it's creators are all dysfunctional, what do we do? I think now it'll be important that while interviewing, I'm going to request a blu-ray movie be played through the receiver so I can see exactly what the receiver detects. Hopefully there are indicators on the AVR that light up when the s/w includes Dolby Tru-HD

No, the 05 & 04 series from Onkyo is OK. It's not always listed in the features but I think will state it somewhere in the manual. Some have phoned the manuf. to ask since it's not always mentioned.
Many thought that the new HDMI 1.3 series from Onkyo's would be able to accept a bitstream signal from their PS3. They didn't realize that the PS3 cannot output the bitstream signal, just decode it and output the decoded signal via HDMI.
-
Well, we do learn something every day. I guess there may be hope for those with HDMI or potential buyers, they just have to dig deep to be sure it will accept PCM. I personally would check with the manufacturer, I doubt if many sales people would know what you are talking about and say anything.
Yeah, sorry, LJ, I must have also given you a good chicklet not so long ago. I was told to spread it around some more. He's gone spreading :)

So where the manufacturer states: "By connecting a player compatible with these new audio codecs to an Onkyo A/V receiver equipped with 7.1 multichannel inputs, you will be able to experience extreme sonic clarity from these new discs[Blu-ray, HD-DVD], while retaining the full use of the receiver’s other onboard codecs." that means that the high resolution formats will be decoded by the AVR, but not necessarily over HDMI, is that correct?
I took that quote from the Integra 7.8's explanation of the 7.1 Channel logo.

7.1 multichannel inputs are for analog cables. No HDMI. The BR or HD-DVD player would be doing the DAC. That's great if you have a BR unit with analog outputs. Not so great if you have a PS3 that doesn't have those outputs.
What sources are you planning on using?

I don't know yet. The DVD changer I now use will be demoted to CD play only, because I like the convienence of loading up five disks, but I don't know if I'm ready to jump into Blu-ray/HD-DVD yet. The Oppo-981, although not a lossless audio player would satisfy my m/c music appetite just fine and is a good value for the money. This is another reason why I don't want to spend the entire budget on processing.

Finally, the receiver's rear surround amplifier channels can be reconfigured to reproduce the front L/R channel signals, allowing for biamplification of speakers capable of this function.
Still need to know if this qualifies the Integra as a receiver with *High Current* amplification.

To coincide with the opening of the new season of American Idol, auditions commence next week! There's a Kellum's (are they a national/regional firm?) not far from work so I'm going to get in touch and see what they've got that I can play with. It'll be up to all y'all to interpret my audio terminology challenged descriptions of what I see and hear.
Meanwhile, I'm spending time drawing up my new and (hopefully) improved room layout which I'll post in the Critique My Layout thread shortly, because there haven't been any hot women falling out of the sky and into my lap lately. :rolleyes:

Okay, what panel thickness did you go with? Wasn't it 2"? I'm going to buy a 6 pack of DIY panels, a roll of burlap and 3M spay adhesive. How did you fasten the burlap to the panel, and how did you keep the fabric taught during that step? I'll buy some sheets of 1/4" backing board and have Home Depot cut them in 2' x 4' pieces. Thanks teach! :thumbsup:

Yeah, don't eat butterbeans and stand next to a candle
AND you have two rear center channel amps, that can also be used for B speakers.
Or you can take the jumpers off of the rear of your speakers, run you mains into one
set, the "B" channel into another.
This will give you bi-amping, not to mention 200 w into each front speaker, but you will have to leave your B speakers on all of the time of course.
Be plenty loud though (havent tried it myself)

I just went through this (finding a home theater receiver) myself. Cost was an issue for me as was being able to drive 4 ohm speakers (Magnepan).
Up to this point I was a 2 channel guy and went the high end route for many years. I sold my Quads and levinson gear and built a homebrew pair of Newform Research R465's powered by a lowly Panasonic XR25 receiver and not looked back since. Ironically, I have the best sound ever in my home.
I always wanted to go surround sound on the cheap and so my search began for speakers and amps. I decided on Magnepan because of the deep expansive sound stage they produce. I takes very good box speakers to do what the Maggies do for very little money. Besides, the models I bought hang on the wall and out of the way of my main system. I can find much to criticize the Magnepans, but that would apply to almost every speaker I have heard at any price. That said, they have one major defect and that is they are 5 ohm and 88dB efficient. Not that bad considering the rest of Magnepans lineup, but still an issue that needs to be addressed with adequate power. Oh, by the way, one of their better attributes is the way the handle voices, very nicely and important to me for movies.
Anyway, to get to the point, I bought a Yamaha RX1800 fo $850 delivered from Audiogon and am in the process of running it through its paces.
I am running Magnepan MMGW on the front mains and a pair of System Audio for the center channel until the rest of the Magenpans get here on Tuesday. Now I realize that this is not a final test, but I thought I'd give you some input to get you interested until then. My room is about 13 ft wide X 18 ft deep (approx). This is much smaller than your room and therefore I do not need as much power as you would. Of course that depends on your speaker efficiency.
At this point,
Power:
Power is a total non issue, there is way more than enough. After hours of watching movies the receiver is barely warm.
Auto setup:
This is a wonderful thing. It sets up all the speakers in minutes and I had only to plug in the microphone (supplied) and press one button. The interesting thing is that since the center speakers are box speakers and the mains are planers the match between them is much better after the auto adjustment then I would have expected.
Soundstaging:
Using only the mains for this test, It was very good. This is one area that Magnepan performs their magic and the Yamaha did not stand in their way. I have also heard Magnepans using Marantz, Integra, and NAD and they all sounded about the same. I heard these in different stores at different times, so take this with a grain of salt.
Menu system:
Awkward but it works.
Equalizer:
This unit uses parametric (auto setup) and graphic (user setup) equalizers. This helps to make all your speakers sound the same regardless of where they are in the room therefore creating a seemless soundfield.
Okay, let's stop here. If you have any questions please ask and I will tell you what I know.
I will tell you this, I am happy with the results so far.
One last point...
When it comes to surround, I am a total amateur here! I'm sure that many patrons of this forum are more qualified to answer your questions, but I still will try to help.

Thanks for the refresher but I've already completed that chapter.
I'm finding the Integra line very hard to come by and I think it's because this receiver is described as an "installer friendly" unit. I read an article where the reviewer had no problems setting it up (and he gave it high marks BTW). My concern is still that I won't get competitive pricing when I'm ready to make the purchase.

Obviously a carpetbagger whos not serious about his butterbeans.
And I hate to tell ya, but lighting farts (at least diliberately ) is consider kind of "gay"
(not that theres anything wrong with that)
And installers do like the integra, its a prepro at a receiver price, if I got a seperate amp
and hooked it up I would have a serious seperates system, which was my original intent,
to step up to a seperates system, the Integra was going to be a stepping stone

It wasn't "gay" back in the early 60's when my friends and I invented it. In fact, it was all the rage!
"Kind" of gay? You're either gay or not gay. There's no middle ground. :rolleyes:

This was my experience as well. No competitive pricing(both places would only do the MSRP$1300 for the 7.8) and no way to audition the unit. I had to special order, purchase and be stuck with it. Not that being stuck with a 7.8 would have been a bad thing :)
My understanding is that the 7.8 offers a few advantages over the 805(build quality, more flexibility.....) but the question is, is it worth the difference in price?
-
Agreed L.J. The hunt is on!
Can some one tell me what this spec from the 804's sheet means? (B&W 804 speaker that is)
Free-Field Response:Listening axis +/- 2db, 31Hz - 20KHz
+/- 30 degree horizontal +/- 2dB to 10KHz
+/- 5 degree verticle +/- 2dB to 20KHz
-
I believe Spearitsound might carry Onkyo and Integra, I've seen both on their "used/demo" page. You might email them, if they carry both Jack is pretty good about breaking down differences between lines of gear you are looking at. If they stock Integra he will allow a reasonable audition and return but it's usually not as long as 30 days. I've always found them a class act to deal with.
I can't blame anyone though for not wanting to buy a product sight unseen and no way to return if it don't satisfy your needs.

If I'm correct that's the optimal listening axis...
I made a little drawing, because I can't explain it that easy (well, I could, but it'd be hard to understand...)
you should aim the speakers so your ears are definately within the 2 outer lines...
you'll get the best frequency response if your ears are on both the middle lines (the optimal listening axis), but this is not always the nicest to listen too, so that's why we play around with placement...
this is why so many people say that the sound is best when your tweeters are at 'ear level', but while this is (theoretically speaking) true, you might more like the sound when you're sitting under the tweeter level, or above...
I hope this was understandable...
(see pic below, note that the drawing is definately not on scale, and the outer and inner line doesn't really form the given angle (30°))
Keep them spinning,
Bert.

Thank you! That's exactly what I thought.
(argument coming soon)
-
If I drew a line 30 degrees out from my speaker to the wall, why would that not be the point where the first reflection is going to occur? According to the procedure for finding the first reflection point that Wooch linked to, the point is where you see the reflection of your tweeter in a mirror slid along a wall from where you're sitting. To me that means the first reflection depends on seating position. That doesn't sound right to me. If the SPEAKER is stationary and the wall is stationary, how can the reflection point not be a constant?
-
The first reflection would not have anything to do with where you sit. It would be a constant, it would only change if you changed the direction, or toe, of the speaker. It looks to me like your figures are showing what the frequency response is inside the speakers optimum disspersion pattern. As you get outside that area the frequency response will not be as good. A speaker is only capable of radiating sound so many degrees vertically or horisontally.
-
So where that 30 degree line meets the first adjacent wall, that's where an acoustic panel should be placed right? And if I toe-in the speakers so that my sitting position is at the top of the equalateral(sp?) triangle, the placement of the panel will be even further away from the speaker. I'm going to need a protractor.
-
The mirror technique will work. Keep in mind the reflection will hit the wall whether it's sound is optimum or not.
I know what you mean though this is about the limit of my understanding or study in this area. I remember the first time I saw 30 degrees given, which seems a common spec, I thought, "this can't be, it's too narrow".

It depends on the dispersion of the tweeter (the Bass is nondirectional)
A lot of dedicated HTS' put carpet or drapes on the wall, looks nice and solves the problem,
but I doubt if that will work in your rather nice living room.
When I got my first beemers, I noticed that some sound was coming from behind me,
in the form of reflections.
STRANGE that we spend big bucks creating a "surround" effect and try to get rid of a natural one. Oh welll...

I can bring home an Integra DTR 7.8 for two weeks to audition. AND, the store will knock $100 off MSRP! (Can you tell I'm leaning towards an Intergra?)
Yes I know... audition audition audition.

I would still give the 805 a try to see how it stacks up to it's twin brother. Yes, I know Integra has a rep for higher quality components, but I'm just thinking how much of an improvement in SQ it will have over the 805, which can be had for half the price.
Also, you should give an HDMI source a try to see if either unit has the popping issue. I would hate for you to purchase a unit to only find out it has issues later on once you get into HD. Mine only happened when using my PS3, but others reported this when using the Toshiba players as well. Perhaps pick up an A3 when you get everything hooked up and just return it. You should be able to rent a few HDDVD from netflix. I guess it wouldn't be a problem if you used the 5.1 analog outs though. Just a though.
