the "updated 6700H" version looks like having 10db more SINAD than non-updated 6700H, not less...what am I missing? (Updated is at 100db, non-updated at 87db)Probably the same as x3700h vs x3800h, as they use the same chips, ie loosing 10db SINAD.
The change happened in Spring 2021.
The first one was a faulty unit. That has nothing do with the DAC change. A unit with new DAC was never tested. But the X3800 measurement should be a good indicator.the "updated 6700H" version looks like having 10db more SINAD than non-updated 6700H, not less...what am I missing?

ok, so basically stay away is the take away, thank you!The first one was a faulty unit. That has nothing do with the DAC change. A unit with new DAC was never tested. But the X3800 measurement should be a good indicator.
Look for serial numbers under 70000. That was according to Denon. Or get an endoscope to see inside.ok, so basically stay away is the take away, thank you!
if you get a good deal on x6700h, I don't think you have to "stay away". Unless you only use it for critical listening, it's still a very capable AVR for home theatre.ok, so basically stay away is the take away, thank you!
Serial number doesn't seem to be anything like 70000 unless you mean the last 5 digits?Look for serial numbers under 70000. That was according to Denon. Or get an endoscope to see inside.
It’s perhaps worrisome that this is your conclusion. Gene from Audioholics says 70dB and above SINAD will be inaudible to most people. (70 SINAD is .03% distortion). So saying to stay away because an AVR or prepro has significantly less than .03% distortion likely isn’t merited, unless you are purposely chasing inaudible improvements for the sake of the engineering aspect.ok, so basically stay away is the take away, thank you!
Yes, last 5 digits according to this: https://www.denon.com/en-us/hdmiadapterSerial number doesn't seem to be anything like 70000 unless you mean the last 5 digits? View attachment 249173
If serial number is under 70000, does that mean it is the low performing capacitor? Is "under" bad or good?Look for serial numbers under 70000. That was according to Denon. Or get an endoscope to see inside.
Serial number is regarding the DAC chip change.If serial number is under 70000, does that mean it is the low performing capacitor? Is "under" bad or good?
It’s not about bullying Denon, but all these customers will have a hard time in second hand market if they choose to let go and upgrade. I wouldn’t touch any x800 series. Previous years you could sell a Denon after 2 years for quite some money where other brands were just paper weights.What's going on here is that DAC chip brand (and SINAD score for that matter) is not a selling point for Denon, and Denon refuses to be bullied into making it one.

Even if that’s true and is debatable, in audio we always overcompensate; buy more power amps than we need, more inputs than we use, higher wire gauge, and an overkill number of subwoofers a room can physically handle. You get my point.It’s above your hearing threshold.
Phrase “Mountain out of Molehill” comes to mind.
