Another possibility, if you are interested in the x8500h, is to purchase it and update the Hdmi 2.1 board later when the problem is solved, but the price difference is important and the surcharge for the update is also important.
No reason at all your M22 amp won’t work great with the x8500. As the person that sent in the T758 for Amir to measure and have switched to the x8500... just do it. The T758 has one thing going for it... Dirac but that can’t overcome the poor dac or very poor amps (both quality and quantity) as the measurements here have shown. In addition, with the app, audyssey is better than Dirac (without the bass management plugin which the t758 does not have) with multiple subs. The Audyssey app is a must purchase though as you can change your room curve and limit the correction frequency. In my opinion it is a very worthwhile move. Check out open box deals from authorized dealers such as safeandsoundhq. Generally they are around $3k or so vs 4k.On a side note, will the Denon X8500 blend well with my Nad M32 (integrated stereo amp) which i use to power the front speakers( B&W 702 s2) with? The Nad M32 is Digital amp but i m sure audyssey will correct the issues? Currently using a Nad T758v3 to power center, surrounds & atmos but very tempted to go for the X8500 as it measures so well.
Thanks.
The 103 is the DAC and the 85 is the SINAD of the amps.Hello there is something that I do not understand in the amir test of his dac it offered a results of 103/104 of sinad and measuring the interior sinad it offered 85db sinad that is due to? Denon says it uses dac akm 4490eq on all its channels right?
Hello if that is clear to me, but if the dac is the akm4490 in preamp mode it also says on the web that the same dac carries each one per channel, right? Or is that dac akm4490 is only used if the av is used in previous mode? In the end if we use the internal amplifiers we have the same sinad using 8 akm 4490 vs a single akm 4458 of the lower ranges?The 103 is the DAC and the 85 is the SINAD of the amps.

Hello, but if you never reached the reference level with the internal amplifiers, would you still have 85db of sinad?I'm not an expert, but I understand that the cause of the distortion is the Denon x8500h's own amplification and the accompanying electronic complexity.
In Amir's tests with two channels, the SINAD differences between the pre mode and the internal amplification of the Denon x8500h are minimal until 1.4v are reached, a volume therefore already very considerable.
From 1.4v, it is when the distortion appears with the internal amplification, quickly dropping to 80db of SINAD with 2v.
Turning off the internal amplification, the source of the distortion, with 2v the x8500h continues to offer a SINAD close to the maximum of 104db with adequate and efficient external amplifiers, and with less electronic complexity.
Hello, but if you never reached the reference level with the internal amplifiers, would you still have 85db of sinad?
Hi, I had planned to put a marantz stage for the front but I don't need power and my volume never exceeds -10 / -5db and I was wondering if at that volume and having monitors and cutting them into small if an external stage is worth it! My idea was to benefit from the dac for preout outputs since amir measured 103db vs 85db of the internal ones but if those measurements are at + 5db I will never be able to go up to that volume ... then I wonder if it is worth it?
illo. I don't quite understand your question.
You mean the volume scale and its reference value 0?
With the help of the data provided a time ago by another colleague, I will try to correlate the volts on the horizontal axis of the SINAD curve, with the approximate level of the volume scale at which they could be produced.
These data are only orientative.
- At -11.5 of the volume scale the data of the curve (0.3v) would start. At this point the x8500h has approximately 93db of SINAD.
- At volume reference level 0, according to the same guideline relationship, approximately 101db of SINAD would be reached.
- At +2 (1.45v), the maximum of 102 db of SINAD would be reached with internal amplification, and it would begin to decline from this point.
- A +5 is when 80-85db of SINAD is reached. This figure is the lowest on the curve and is reached with 2v, 5 points above the reference volume level.
Cheers
To be clear, that's for measurements. When in use for music, it depends largely on the input signal (music), that varies continuously, and in large magnitudes, 20 dB swing on top of the "average" level is not uncommon.
Hi guys, I've been changing settings in the multeq editor app all afternoon and I don't notice a big change, do you notice when you apply curtains to audyseey or deactivate the midrange compensation? What are your settings for film and music two channels?
This is part of the reason why I think obsessing over SINAD of good AVR's vs dedicated amps and DAC's is often meaningless in real life and blown WAY out of proportion.illo. I don't quite understand your question.

Hello Peng, thanks for context, I wanted to say that I do not notice an auditory improvement that makes me decide between one thing and another ... by the way since you handle sinad and it is still not clear to me I was thinking of putting a two-channel stage to see if I took advantage of the good sinad of the dac but could you tell me if normally listening at a volume of -10db on the absolute scale that sinad would take out the 8500 with the internal amplifiers? We already know that the preamp is 103dbI guess it depends on what you did and how you define "big change..", and whether you meant the difference was not very audible. If you use something like REW and an Umik-1 mic you should see very obvious change. It could be something that is easy to see, but not so easy to hear, like the difference between 80 dB SINAD and 90 dB SINAD. "Big change" to the eyes but may not even be noticeable to the ears, depending...
