Denon x4800h vs Marantz Cinema 50

[PENG]

Nah.... I will just take your word for it.

Thanks, regardless, I posted the link to the video before but for a quick reference in case others are interested, below is the screenshot of the preamp/dac block diagram from the video:

Obvious this is Marantz as you can tell by the presence of the HDAM, Denon's will be the same but without the HDAM.

You can see that even if the HDAM (discrete Opamp) does have better slew rate, it's performance will still be limited by the upstream components such as the DAC, opamps, selector (also solid state ICs), E. Vol (SS ICs) etc.,. Assuming the HDAM does offer lower impedance, it also doesn't matter because it also has an opamp right in front of the power amp (not shown in block diagram, but clearly shown in the service manual for the previous models such as the SR6014 and presumably newer ones) that are ICs, that is, not the discrete type like the HDAM. Amazingly, the OPAs positioned after the HDAM but before the power amp inputs were shown to be there for the front left and right channels though, as noted by bigguyca.

The diagram shows analog input signals, if direct or pure direct mode is selected, it will bypass the ADC (not shown) and DAC but cannot bypass the E. Vol and the HDAM.

Amir (ASR) said he had finished the review on the AVR-X4800H and sent the results to Denon Japan, so now we just wait..

I decided to pull the trigger on the X4800h.
I want to thank everyone for their input and thoughts. I listened to you all. I anxiously await Amir's test results, although I suspect that performance improvements may be marginal, however, better build quality, better components and the way that the monolithic power supply allows for discrete individual power boards per channel, which allows for increased space between the boards and subsequently, in theory, should allow the unit to run cooler and with less cross talk. Will it make a audible difference in sound? We'll know in just a few more days. But for me, the build quality, better components and significant price vs features were the deciding factors for me. If Amir's results show a notable increase in performance, then that will just be icing on the cake. Thanks again to all.

According the member who sent the unit in, ASR now has the response from Denon Japan, and we may see the results published sometime today.

My prediction, based on hints reportedly dropped by Amir a while back, SINAD (again not emphasizing the importance as it is just one metric) will likely be in the low 90's.

Given the DAC IC's spec is 93 dB, if the 4800 can get close to that, say 92 dB at 2 V, it will show D+M has done an excellent job in their implementation.

As preamble, in case people starts to compare, for reference, the Marantz AV8805A managed just below 92 dB and the AV7705 managed just below 75 dB, at 2 V RCA or 4 V XLR. Denon AVRs had done better than the Marantz AV preamp/processors in their pre TI DAC chip versions. "separates" don't always perform better!! Yes they should be better in reliability all else being equal as they should run a little cooler, and XLRs are nice even if it doesn't improve on SNR significantly in most cases.

However, the new Marantz AV10, should do better than AVR/AVP ASR and Audioholics have measured so far, based on the info in the Masimo video. Hopefully Gene will be publishing the results soon!

Gene? How goes the AV10/AMP10 measurements?

Denon AVR-X4800H AVR Review

This is a review and detailed measurements of the Denon AVR-X4800H 9.4 home theater receiver. It was kindly drop shipped by a member and costs US $2499. While the look is the same as previous generations, the feel of the control knobs is much improved which I appreciate. Menu system is also...
