You don’t that it’s weird Denon did not send him one?Why should Amir comment other posts? He believe only his own findings at a measurement run. I wish someone can send him a 3800h. He would joyfully check the improvements of the new series.
No.You don’t that it’s weird Denon did not send him one?
The 3700 manual says:The previous X3700 and up all shut down the amp. See Amir’s reviews. Mine certainly does. So it is very very likely the X3800 does too in pre-amp mode.
Is it really a full shut down (power off) or only a disconnect, when they “stop their operation”? I thought the consensus here is they disconnect only.Set “Assign Mode” to “Pre Amplifier” if connecting all channels to the Pre-out connectors using an external amplifier. link
This stops operation of the internal power amplifier of this unit, reducing interference in the pre amplifier created by the power amplifier.
In my response I didn’t distinguish between power off and disconnect. In pre amp mode the amp runs cooler and SINAD improves at least for the X3700 and higher models. If that is achieved with power off or disconnect, I don’t know and so far I didn’t bother. It just works. ;-)The 3700 manual says:

The silence from Amir worries me too. Not a single comment about 800 series yet. I know my position on this. Mine was delayed to the hurricane Ian, so if/when it finally delivers, I’ve 30 days to return it. If noise level is more than my 3700, I just keep that one for another year or two.
Got it, thanks for that. I just looked and the X3800 user manual also says the same (page 44).
I must be thinking of the previous X3600 where there was just a disconnect vs a shutdown.
I doubt Amir has a X3800H from Sound United. I suspect we will need someone to send one in ASAP to know
There was much less of a marketing push this round compared to prior launches in my opinion, suggesting some change from the higher ups. We did see a nice interview in Japanese and a new set of detailed discussions in French though. But we still have very limited data about the Marantz gear.
There is also a lag between the Shirakawa products and non-Shirakawa products being launched and the use of the PCM5102A which is good but not as good as the AK4458’s used in the past.
At least for line level outputs, anyone can test a receiver with an E1DA Cosmos as pkane’s Multitone software. That’s the real trick going forward. Look at how having Erin has increased the speaker measurements we can get. The APx555 and APx585 are better but if we want gear like the RX-A8A tested it will have to be home brew.
Amir has had good communications with Denon engineering team and I think they respect each other. It is not even impossible that he was sent an early unit for comment, but he was under NDA so he can't even talk about it.I doubt Amir has a X3800H from Sound United.

That’s what I thought too. (That he had a unit). But once the products were annnounced and units actually made it to end customers, the lack of a review or even preliminary article of some sort suggests that they haven’t.Amir has had good communications with Denon engineering team and I think they respect each other.

I was about to create a thread to see if anyone in the US would be willing to send him one, and we all chip in for shipping cost/insurance.
Isn't Pure Direct Mode bypassing any room correction by Audyssey? (it does in my old Onkyo AVR). If yes, then bigIn our test room, we use Audyssey MultEQ XT32 to calibrate our 7.2.4 system, which uses Dolby Atmos toppers. For most of our reviewing, the AVC-X3800H is in its Pure Direct Mode.
This is the kind of review we all want to avoid. Quoted from the same article:Review by whathifi https://www.whathifi.com/reviews/denon-avc-x3800h

Yeah I know Whathifi is famous (or infamous) for their (non sense) subjective reviews, but "reviewing" an AVR by running calibration then bypassing them is a new level of incompetency.

I think he already made this review.@amirm can you please share if you are testing this or if you got one to review? I knew several US members were planning to send you one. Waiting for your review to make my decision
Actually, I think more than likely you were right in the first place, that the amps would still be powered whether disconnected to the pre outs using the amp assign function or preamp mode. It might have been possible that the newest models do power down the power amps but according to Gene that is not the case.
Unless someone can confirm the otherwise, I would assume the X3800H, like the X3700H in amp assign to pre out or preamp mode just disconnects the inputs of the power amps to the outputs of the preamps. That means the power amps will still be connected to the power rails and receiving bias currents. Technically speaking, in some way it is not a bad thing to keep the power amps "powered" anyway.
