Denon AVR-X6800H now released.

Sorry, if you do it sighted, that is, you know which one you are listening to, it doesn't matter what you think, and I am more or less (just not the exact words) quoting Dr. Toole.
But, if you think so, that's great news regardless! That's assuming you compared them under the exact same conditions and switched between them without even a few seconds of delay, others there are just too many factors anyway that has more audible effects than the different DAC ICs. The preamp really is just the volume ICs that are identical so no impact.

Remember the previously posted block diagrams:

The following slide in the Masimo presentation shows the "common technology" used in both, that confirmed 100% the preamp/vol ICs and switches used are the same.

I won't rule out if you have very discerning hearing, you may be able to hear the differences due to the better build quality of the 6800 that likely result in measurably better SNR, DR, SINAD, cross talks, IMD etc., just that results done without DBT or at least SBT, level matched to within 1 dB or better, and other controls won't be reliable.

The DAC IC difference in specs and their implementation between the two are indeed significant, there is no doubt about that, the only question is, how audible the resulting difference would b? I don't think anyone knows the answer, but all can, and some have, speculated.
Of course you’re right. I myself don’t buy that digital scoring (SINAD etc. ) result in better sound. What I don’t know is what the effect of different electrical components are. Nothing has changed but the box; cables, connectors, speakers and power amps are the same. Still I can recall not being happy with stereo music via Apple Music through the previous setup without Audyssey ‘on’. Direct wasn’t nice. Now it is… So the ‘investment’ is paying off. Apart from being the best deal ever because of BF.

Good to know you are so happy with this value king, at the current sales price point, it is as good a deal as the X3800H that is at the lower/mid range level whereas the X6800H is at the near flagship level. 16 channels of high performance DAC+2 more for one of the sub-outs, tons of license fees, compatibility with DLBC and potentially ART, plus 13 channels of power amp, sometimes I have to wonder how much money can Denon make on this.:D I guess vs Marantz, Denon must be making up their much more margin (just notice the X4800H is also on sale now, in Canada anyway) on much larger sales volume.
 
Hello,

I try to do second Dirac calibration with my X6800. However I have static noise when the measurement sound is emitted on the fourth and last subwoofer. Measurement is done but such noises inevitably have a negative influence on the measurement result. So I stop and I reversed the RCA cables at the power-amp input. Result those noises are change of subwoofer, so the problem come from X6800 when it generate sound measurement for the last sub.
Has anyone experienced this problem before?

Thanks

Further back in this thread it is mentioned that the 4th sub-out is using a different DAC. I think that shouldn't be (that) audible, so I'd suspect a hardware issue?

Check to see if tactile transducer has been disabled!

Support told me the only fix for the eARC issue was to send in the brand new AVR for repair. Did theny ever have a fix for the random black screen issue?
:p
Yes I posted about it a while ago...


Just a reminder, I don't have the 6800 but rather an 8500. I'm sure that this was a completely different issue than others who reported HDMI dropouts were experiencing. I can't speak for them as to whether they ever got it resolved.

I've been getting black screen dropouts from my UHD player. It seems to come and go. Some days I can play a whole movie with zero issues, then another day the 6800 loses input signal every so often, could be once an hour or once a minute. AVR is connected to eARC port on an LG. Is this a similar issue to yours? Are you still experiencing issues?

I return the 6800 as they had no fix at the time for the different issues and the 6500 worked fine with the same cables and devices. They messed something up with the 6800.

The 6800 issue I had was that (no mater what I was watching) it would once a day or so go to a black screen and would not come back until power cycled.

The random dropouts could be the HDMI cable, if it just from your UHD player. It can be a pain but I'd try whatever different HDMI cables you have. Get the shortest you have and move the UHD player if you have to. The randomness of it makes it hard find the issue. I had a 25' Monoprice that work fine for years and then my Oppo clone started to do random dropouts with 4k movies. It could still get through a full movie from time to time but it was fixed when I got an active fiber cable for 4k 120Hz gaming.
 
Indeed, it can be an hardware issue :(
For my issue with Dirac measurment with 4 subwoofers, I got an answer from Europe sales representative and for sure the issue come from Dirac. This also explains why the ART feature is taking a while to come...
I will iterate with my reseller to find a solution. In the same time a friend with the same X6800 using also 4 subwoofers do not have this issue.
 
Dirac is overpriced and overrated.
Over priced is depending on what we as a consumer expect and them (Dirac) as a supplier can base their business model on. I do think it's a steep price particularly if you take into account having to pay extra just to be able to manage extra subs. Overrated I do not agree with. I said it before; I was reluctant to spend the money on it until Black Friday and an excellent deal on an H6800X. It made sense to also try Dirac and in my experience it gives a better immersive result. No measured it but as I tend to listen with my ears and fully subjectively decide what I like best I give my kudos to Dirac.
 
I'll consider an AV receiver from Onkyo, Pioneer, or Integra when it is confirmed Voxx/Sharp is no longer building current models with a circuit to throttle output power as measured by Amir in his reviews of the Pioneer VSX--LX505 and the Onkyo TX-RX50 AV receivers.
Per Audioholics the RZ70 has no throttling and they gave it very high marks for performance. Check out their review.

"Overrated is in the eye of the beholder".

I don't like their pricing either but the base Dirac Live license gives us another room correction option (which gave me the clearest dialogue from the center channel compared to Audyssey, MCACC, etc.).
