With AVRs/AVPs it's still a mystery what real life results you get when Audyssey or Dirac processing is turned on. @amirm should make a test setup that allows to run at least 2 channel room calibration and then measure thd, sinad etc. I believe that requires just a suitable audio mixer, no speakers or mic are needed.

Marantz AV10 AV Processor Review
- Thread starter amirm
- Start date
Can a crossover be used and still remain 100% analog?? I doubt it
Yes it can, if it is an analogue crossover.... but it is pretty unlikely in an AVR
Yes, in an AVR I mean
I found this. Not sure if true, but would explain why you see no frequency response drop at the nyquist frequency and why Marantz says there is an ADC.
(Basically they split the analog signal)
No, room correction is disabled for these measurements.
I used to think that, ie a split signal is/was used in some cases; and still think that is possible, but I doubt that's what Marantz told Deckard71. If you read the Marantz response he posted before, you will probably agree with me on this. In fact I thought I posted that hypothesis too somewhere, and long time ago too, don't remember where I posted the idea, likely Audioholics.com. Still in doubt is that, the speaker small, crossover thing does not seem to be applicable to the sub only.
So, on that part we are still left with doubt, just a little doubt that is. Marantz did tell me he traced the analog crossover, so if it is analog then, puzzle solved!!

Even with room correction disabled, could it not be in general reserve, considering the user still has the ability to boost individual channels and frequencies?
Over the years some higher-end Denons and Marantzes have had the ability to generate subwoofer output using fixed 80Hz analogue LPF from L+R in "Direct" type modes. It would not be surprising for an absolutely top-end model like this to have that facility.
I've never seen them do more than that in the analogue domain though - so not HPF on the mains to create a full analogue crossover. I'd agree that's unlikely.
The subwoofer LPF option is satisfying a particular customer complaint of "my subwoofer doesn't do anything in Direct mode". A fair few people do seem to want "untouched audio" and "subwoofer output" simultaneously...
There is this thread as well.
Direct, Pure Direct & Stereo with Audyssey by-pass
Like many of you here I am a constant tweaker. Thanks to @amirm and @walt99 I am using an A110 with a Node 2 via coax to Gustard X16 analog to the A110. I've been listening to 2CH via Tidal and NAS in Pure Direct through my LSiM 707s and it is remarkable. I'll spare you all the subjective...

Marantz AV 10 15.4CH 8K AV Processor Bench Test Results
The Marantz AV 10 15.4CH 8K AV Processor produced excellent bench test results. This $7K AVP has bass management features no other competitor has at this price. We thoroughly test to show you how it works.www.audioholics.com
His analog input test look like the following:
I am curious as to whether or not using this test would have answered some of the questions in the discussion below especially post #460?
Review and Measurements of Marantz AV8805 AV Processor
I don't want to belabor this point, but there are other settings, such as double-bass, available in pure direct mode. Not acccording to the manual. . Therefore, Pure Direct *may* perform an A/D conversion based on other settings. In Pure direct mode signal processor is off so what would be...

Post #460 there is nonsense - there is absolutely a direct 2-channel analogue path to the L+R outputs in every Denon/Marantz I've ever seen. (Which would be mid-to-high-end ones like the 5805 or this; I won't rule out the possibility of there being a low-end one not having it).
It is less obvious than the direct multichannel analogue path because there's also the ADC->DSP path for 2-channel analogue input, whereas the multichannel input is analogue passthrough only, what with them only having 2-channel ADC except in very few top-end models. The poster there has seen the 2-channel ADC path and missed the analogue path.

Seems like the AV 10 might match up well against the Anthem AVM90

Marantz Amp 10 next, to compare with dual Buckeye Hypex NC502MP 8-channel amplifiers - as with pricing, warranty, design, fit & finish, 2 boxes vs 1, brand longevity, brand recognition for resale, international support - all being different, they definitely represent different aspects of the value proposition.
DLBC shows as available for Cinema 40 on Dirac page.
Marantz CINEMA 40 – Dirac
I am sure all other eligible D&M AVRs and AVPs will follow soon

I disagree. The cost of developing a product affects both its profitability and the decision to build it. Yes, R&D tax credits exist (in the US at least, but most products Amir tests are not developed here. I don't know how it works elsewhere.). If a company is choosing between launching two products, both of which will have the same BOM/labor costs, have the same transfer price and generate identical sales revenue, but one will cost $2M to develop and the other will cost $20,000, which should they build? No smart company says, "R&D costs are irrelevant -- we'll just write them off." A product is financially successful only if it delivers profit AFTER covering its development costs.
I doubt it... the main loss of SINAD is to do with gain matching between different circuit components that are "off the shelf"
@Amir - I don't understand: "As you see in both graphs, optimal output is more or less what you see in the dashboard. So don't go getting a very low gain amplifier thinking you are coming out ahead. Likely a medium gain amp is the best combination."
My system uses very efficient PHL & ViaWave drivers (95db+) and I don't anticipate a need for anything close to 200W amps - 60W may even be excessive.
Is this an exception to the above underlined recommendation?
I'm also considering the Denon AVR A1H or AVR 6800H given that my amplification is not balanced, will my system suffer diminish performance under lower voltage RCA output?
Thanks!
