It's a really good overall video as well. I love that they put these videos out like this and they really do a great job diving into the inards of the system and some of their design choices. They have them for AVR-A1H and other Cinema series too if I recall.
They likely used 96 kHz, that won't make much different unless select the slow roll off filters (default?), in that case you may get closer to 100 dB but I doubt it would improve to 106 dB. They had volume set to 82, input is the same as yours, 0 dBFS for sure.
No one else has done it, but Audioholics can be the first.
yea SINAD was unchanged when I changed to Fs = 48kHz. I will reach out to my contacts at Masimo to better understand their test conditions. We are in the weeds when dealing with such low distortion so it's difficult to repeat these results sometimes.They likely used 96 kHz, that won't make much different unless select the slow roll off filters (default?), in that case you may get closer to 100 dB but I doubt it would improve to 106 dB.

Again, please do the FFT using 3.5 kHz or somewhere around there, if you don't mind and obviously if possible at all...
You raise a good point that I may have missed. Gene, was this with the DAC filter setting ON or OFF? I'm curious which setting you used....and sorry if I missed it. Personally, I have it turned off on my AV10.They likely used 96 kHz, that won't make much different unless select the slow roll off filters (default?), in that case you may get closer to 100 dB but I doubt it would improve to 106 dB.

Thanks for the info. I will watch with interest. Although my rig sounds really good with the 7705, so whether the results would be worth the expense is actually debatable.According to Marantz Support website, there will be a rackmount kit option under development, but who knows if it is accurate

Hi Russ,
The release date for the rack mount kit for the AV10 has yet to be determined. We're hoping very soon.
Sub-woofer 1 is the primary subwoofer connection, and its differing panel color is to help indicate that it should be utilized before the other Subwoofer preouts. A similar theme can be observed for Monitor Outs and the Main Five Speaker Channels.
Really appreciate you showing your true color, that is, being a real engineer who just have to know the reasons for everthing, aka osd haha
I've opted to turn it off to be a more typical fast linear roll off...not sure what this will mean measurement wise though.
That sh1t would make me lose sleep if I can't replicate and confirm.Really appreciate you showing your true color, that is, being a real engineer who just have to know the reasons for everthing, aka osd haha
If I understood right, it is not a on/off thing, but Marantz now allows you the choice of using the Denon's chice of the fast roll off filters, or the Marantz's choice of one of those slow roll off filters. The slow roll off filters, being slow, will result in having the harmonics in the ultra sonic band. The fast roll off will behave more like a brickwall, removing frequencies above around 22 kHz if the sampling rate is 44 kHz, along with the high order harmonics.As a lowly non-engineer here, I'm still curious to know how the new DAC filter on/off impacts measurements. Everybody hated the slow rolloff DAC filter so now they give us a way to turn it off so it would be good to know what, if any, impact there is.
Yeah. As clean and inaudible as 96dB SINAD is, 106dB seems like a “huge” difference in measurement. So I am sure Gene and Masimo will get to the bottom of this.Thanks for posting that. I was going to say that I think Gene has watched the video now but in glancing at the SU measurements I noticed that the SINAD was 106dB with HDMI in....just as I think Gene tested. Hard to believe using DAC filter 2 would make up the other 10dB, but to fair, the feature is literally described as being useful for "benchtests."
Either way, I'm sure Gene will figure it out. This thing is super clean, loaded with features not see anywhere at its price point and its gorgeous in my room. It is so cool to be seeing some very nice AV gear coming out again after the AV-zombie-apocalypse (COVID).
Filter 2 will get better test results mainly in terms of flat FR to 20 kHz and a touch higher SINAD, may be 1 to 2 dB, not 10 for sure.Thanks for posting that.

Awesome test bench review Gene! Thanks again! You are now my one-stop-shop for everything my credit card doesn't need..
.. Now, how can I help you get rid of that Storm processor?!?!? I wouldn't want to see you suffer any longer with it when you can just keep the AV 10.....
Nice try. The AV 10 goes in my family room system. Storm stays in the theater.Awesome test bench review Gene! Thanks again! You are now my one-stop-shop for everything my credit card doesn't need..
The .0005% THD or 106dB SINAD measurement in the Masimo video happens at 22:08 and they labeled it as Analog Unbal In and Analog Bal out. At their Vol setting of 82.5, you'd have to drive the input to > 6Vrms to get the output to reach max level. This is why their max unclipped output was 9Vrms instead of 12Vrms like i measured.Thanks for posting that.

It will hit rated power with 1 or up to 7CH driven as per my bench tests. It's a very interesting amp. Does great ACD but has no headroom above rated power. I will be discussing this in my test report.From Masimo Video.
AV10: SINAD 106dB
AMP10: SINAD 95dB
