Great, looking forward to your review. Do you know how soon you'll be getting one of the units in?

As soon as they start shipping, Dec timeframe I think.

any word how these handle low impedence speakers?

mmiles 11-11-2015 01:37 PM

AC December but more like January 2016

When you look @ past bench tests* of previous Arcam receivers; they are capable into 4 Ohm loads (2 channels measured).
The AVR850 should have no problem because 4 Ohms is included in its specs (check Arcam's own website).
And the AVR550 should also be capable, even if 4 Ohms is not included in its specs (when using a sub or two).

does anyone know if the avr750 and avr850 have fans in them? my avr300 which I still have has issues with the fan noise so just wondering about these two units? thx

The AVR750 has two internal fans, so I am 99% sure that the AVR850 and AVR550 have as well.

is there a way to tone down the output sensitivity of the subwoofer preout when adjusting trim levels with spl meter? there is a major difference here when compared to avr 300.

They're both highly regarded of course. And then, if Dirac seems to be better, is it really $900 better?

Dirac, it's in his own class, those Swedish dudes all they do it's room correction :)

AVR 550 compare to MRX 720.. I'll take the Arcam any day.

mmiles 11-16-2015 07:14 AM

It's looking more like January.

DS-21 11-16-2015 05:32 PM

Any word on whether the Arcam and AudioControl units suffer from the same DSP horsepower limitation that precludes using Dolby Volume and more than 7.1 channels, like the Yamaha AVRs and the forthcoming Anthem AVMRX's (as Nick reported in the Anthem thread)?

I guess I missed that part.

mmiles 11-17-2015 12:50 PM

DS-21,


Good question will try to get an answer.

One feature that the platforms share is pretty cool. You can use Rear LS and Rear RS for 2 of the four Dolby Atmos channels. So all you need is a 2 channel amp to run 5.x.4

gbaby 11-17-2015 02:14 PM

I have owned two Arcam products: the AVP700 and the AV9. I did not get good service from the USA dealers on either product. This was after paying retail for both products.:eek: Buy at your own peril.

NorthSky 11-17-2015 02:18 PM

I've read horror stories from owners of Arcam hi-end pre/pros and receivers; and right here too @ AVSForum. ...But that was a while ago; perhaps today they are better @ resolving passed issues? ...Only time will tell for sure.

That's true, 2 lines back (the avr600 line) were absolute crap, a speaker destroyer machine, which almost bankrupted Arcam. Then a Canadian company acquired them, and who's leading that company now did a very very smart move with the Dirac.
The old fashion management didn't believe in room correction at all.
Before Dirac in Arcam the best choice was Anthem, now that has changed. AC could be the better option(design and made in USA), time will tell.
I own an MRX310 and it's still not quite there in terms of surround performance.
Cheers

mmiles 11-17-2015 05:12 PM

I have no experience with Arcam but owned and installed AC products.

Amps are rock solid and a true value. I never installed the AVR's

I did own and have sold the Maestro M3/M4 prepro. These units indeed had issues. That said AC stood by them even after warranty expired on one unit. In fact I still use one today.

The OEM is the same for both platforms as I have mentioned. Just look at the back panels on the units we have discussed. I'm sure the OSD menus are stroke for stroke too.

I have been told there have been big strides made in the product.

Filou6901 11-19-2015 01:35 AM

I have the Arcam AVR 850 ordered !
Question :
Have Arcam a German Menu ?
The Arcam have 2 x Sub out , both edited with Dirac ?
The Setting from Crossover is 10 Hz steps ?
Sorry, come from Germany,my English is not so good !!!
Very Thanks !

1. Page 51 => http://www.arcam.co.uk/ugc/tor/avr85...-IT-R-SC_1.pdf
{I don't know if it is mentioned in that manual (no it's not mentioned); you probably mean the GUI Menu - German language. ...I bet it has.}

2. I don't know if the two Sub outputs are equalized separately and then summed up as one by Dirac Live.

3. In the manual, starting page 51 from the pdf link above.
It very well might be indicated (no it isn't; I just checked - but I would think so for such a hi-end AV receiver).

One aspect worth noting is 96KHz / 24 bit support... in my opinion that should be more than enough even for the most discriminating listeners:
http://www.arcam.co.uk/ugc/tor/avr850/Dirac Flier/Dirac Live for ARCAM.pdf
The sofa image in that flyer may lead to think that measurements should be taken in one horizontal plane but that is not the case... this larger one is probably better:

Almost all the AVRs out there if not all, will down-mix to 48kHz before any processing.
Only few pre/pro are able to process at 96kHz.

So having Dirac processing at 96kHz for 11 channels in an AVR that's pretty cool I'd say.

Any word from users on whether Dolby Volume and Atmos work at the same time?

Also,

What's this "Interestingly the height channels have all the pre-calibration measurements, and feature a target, but as soon as you run the optimization (and talks to the Dirac server), the target, and post predictions disappear from the height section."?

(From your above link)

Filou6901 11-25-2015 09:54 AM

Dirac does work , when Loudspeaker connect PreAmp out ?
So you need Laptop for the Arcam Dirac, or TV Display ?

flax 11-26-2015 08:28 AM

@ DS-21
my understanding is that the height channels (in case of a 7.1.4 configuration) are "italic" and "greyed out" because they are corrected for gain and delay but not for FR and IR (not unreasonable for an helicopter in the sky, rain, etc..)

@ Filou6901
yes, a full fledged computer is necessary for the initial measurements and calibration

I think that is extremely unreasonable, actually. Unreasonable enough to disqualify these boxes for me as serious alternative at their price points. Maybe at $1500, or about the cost of a generic AVR with preouts and a miniDSP Dirac box, that would be a reasonable compromise. But at bleeding edge (for an AVR) pricing, no way.

I could care less about helicopters and rain. I'm interested in reproducing the acoustics of music performance venues.

Is the real issue that there's not enough DSP horsepower in the current chips to do things properly? If so, then the choice to raise sampling rate to 96kHz instead of implementing EQ properly was a mistake, because that wastes resources for a dumb marketing point at the cost of a useful feature.

I thought I was going to buy a new AVR or pre-pro in 2016. But given the crippling limits that are emerging in better models (no loudness compensation when going beyond 7.1 channels, incomplete room correction) I've yet to see a product compelling enough to replace out my base model ca. 2011 Anthem.

That's a good point so I've investigated and from what I've heard the 96 KHz support is for Stereo while multichannel is at 48 KHz because of DSP limits.

So what pre/pro are at 96K?

It seams it has been stated the Arcam/AC is 96K in stereo but 48K in multi channel

I agree that the notion that the height channels are of lesser importance when it comes to EQ is false. Do we know if it's just the 550 that does this, or does the 850 also omit Dirac EQ for the heights?

nadyn 11-26-2015 08:47 PM

[QUOTE=mmiles;39254170]So what pre/pro are at 96K?

Anthem D2v.

But in reality there are not many BD disks on the market that are mixed at 24bit/96K for surround.
