Of course, but the Denon 3800 should be compared to the Cinema 50.also this is twice the price of the denon 3800 so.... make your peace, pay the price?

Pretty sure the lower ohm settings on most AVRs actually impose a limit on rail voltage or some similar effect to prevent more power and heat.The values for 2ohm were determined in the imp.sel. 8ohm position, correct? I don't know the exact protection design of this AVR, but couldn't it be that even more current is tolerated for 2ohm in the 4ohm position?
Has anything like this ever been measured?
Velben goods, my friend... idiots and velben goods.Now imagine you can buy this or super conductor cable for your abyss 1266... For roughly the same price
If the high-end in audio is not the most overpriced thing in the world I don't know what is.
That is a no. If you compare the the graphs side by side on dual screens, you will see they are virtually indistinguishable (you don't have to be an engineer but you should make sure the axis are the same and/or similar range when comparing).ok so for the understanding of the other 99 percent non engeneering background readers of this forum... is it correct to deduce that the C40 is far far superior to the X4800 and the price difference is justified....?
because everywhere we read people say the x4800/C40 have identical components inside and sound the same and perform the same and that all the C40 gives over X4800 is asthetics.
I wish it was just overpriced, it would means its expansive but by increasing price you slowly get increasing quality, its straight bs, because its based on pure speculation and LIES.Now imagine you can buy this or super conductor cable for your abyss 1266... For roughly the same price

It should as HDMI is certainly the most common source. The "issue" if you call it is that I use my computer as HDMI source. Everyone else uses an HDMI module in the AP analyzer. From past interactions, it seems that the AP generates a cleaner HDMI signal (as it should). Is a standard HDMI source (BD player) as clean as the AP HDMI module or my PC? I don't know. I need to measure that at some point.
Meanwhile I asked AP how much their new HDMI module costs. I think they said $7,000! And it won't fit my version of the APx555 to boot. So I can't do any comparisons.
Perhaps the distance between the audio signal wires and the surrounding electronic components? Some audio signal cables from inside are ribbon based instead of being fully shielded. The PCBs are designed in a way to better fit inside the case than to be designed to better measure on Audio Precision equipment (which may not fully apply to stereo amplifiers where 20-30% of the case remains free), so things like shortest path or star grounding may not be prioritised in AVRs where several PCBs are stacked on top of each other to fit inside the case. Just saying...[...]
To me, based on the measurements, D+M has done a fantastic job implementing the preamp/dac in their C40 and AVR-X4800H, or even the AVR-X3800H practically speaking. The only part I don't like, not that I think it matters audibly speaking, is their poorer performance in IMD, and I wonder why, any ideas?

The Denon A1H (and presumably the Marantz AV10) moved to the ESS 9018K2M chips, so it’s entirely possible the rest of the lineup has switched to ESS as well.Many thanks for an excellent review that includes measuring the pre out level up to 4 V, and reactive load tests on the power amps down to 2 Ohms. I think you may be the first reviewer who included those two tests in one single bench test session. Again, thank you for the nice desert!!
It looks like D+M did manage to squeeze the 93 dB SINAD spec TI PCM5102A dry, totally dry. They should patent their DAC chip implementation for achieving the seemingly impossible 98 dB SINAD you measured on the pre outs using Toslink. Even if they use differential implementation by doubling the number of the PCM chips, it doesn't seem possible to reach 98 dB when the spec for the chip all by itself is only 93 dB. Differential implementation mainly benefits in term of may be up to 6 dB noise reduction at the most anyway.

Based on the pre out performance of the Cinema 40 and the AVR-X4800H, may be D+M/Masimo has secretly replace the PCM5102A with a better one such as the ESS's ES9010K2M??
Understood, sorry I started this, but I think you can see why, as you likely know many members were not happy to find out SU replaced the AKM chip with the TI chip that has much lower SINAD specs. So now we see good results from the 4800, 70 and the 40, and some of us bound to wonder why, it is totally on topic imo but I will comply with your request.Let’s all do our best to stay focused on this review and not get sidetracked by discussing Chips and other thread drift topics. First 20 pages we want to keep on topic.
Please and thank you for your Cooperation and understanding.
The question is whether it will be upgradable to ART when available.You can purchase Dirac Live and Dirac Live Bass Control (DLBC) for this unit at:
Currently DLBC is 30% off until Jan 15, 2024.
You can also compare all DLBC capable AVRs in my comparison thread. See signature.
I asked this question, but got no response from the guy who's got the insider info about Denon/Marantz.The question is whether it will be upgradable to ART when available.
