I haven't tested to confirm this but I will ask Denon if this has been fixed. If this is true it would apply to ALL of the speakers so it shouldn't really be much of an issue.

This should never be a problem if you use a laser ruler or auto set up to set distances. Keep in mind this is all perfect for one seat location only.

Agreed and they should be included on the new THX and Dolby calibration discs. I will reach out to my contacts to both companies and request this. We should have the ability to test up to 9.1.6 speaker formats. Anything beyond that requires a Trinnov or Storm Audio processor which has built in...

Yea I requested the Spears & Munsil disc that just came out and will see if it has that capability.

I think the 2nd edition Atmos disc I have does phase checks. I will have to dig to find it. THX calibration discs do phase checks for 7.1. Again, there are 4 ways you can test phase of the height channels without a disc: 1. Use auto set up and let it check phase, they usually get this right...

The Dolby Atmos demo disc does 7.1.4 which is the limit to most test discs. 95% of people are using speaker configurations under this channel count. Checking speaker polarity and using a laser pointer if you don't trust auto setup gets you there for higher channel counts.

The latest ver of YPAO on the RX-A6A nailed delays and trim levels. You can also use a laser ruler and aim at each speaker with very precise results as I shown here: https://www.youtube.com/shorts/eOFcwj_UPT4 Phase tests between channels is readily available on Dolby and THX test discs for...

My thoughts, for the layman, auto setup systems like Dirac, Anthem ARC, Trinnov, Audyssey and even YPAO already accurately set level and delay for ALL channels except sometimes the sub. Anything that requires more than level and delay calibration and phase should be done in REW with...

All isn't lost. You can still use the other discs available and compare your results and you may find their test suites are accurate. Or, use REW and the files I linked to.

This is typical for 3 way designs that often invert the phase of a driver for proper acoustic summation. Most streaming apps like Tidal have phase checkers.

Especially since the test files are available for free here: https://drive.google.com/file/d/1dgrL-hDfX_AvLfERHZXqyK3__z_7vXgR/view?usp=sharing https://www.avnirvana.com/threads/dolby-atmos-and-rew.2184/page-3

REW has test suites for this available on AVnirvana I believe.

I cannot recommend that disc at this time. It's a bit expensive and AFAIK they may NOT have a licensing agreement with Dolby to be using the Dolby render software in their video NOR has it been vetted by Dolby despite they are marketing it as an Atmos calibration disc. Dolby has demo discs that...

You need to still use 1/24th oct smoothing but reduce vertical scale to 50dB. Also, measure multiple points, not single point. You can then spatially average the cluster of measurements without smoothing to get a better picture of what's going on.

Added Onkyo write up since it shares same platform as Integra: https://www.audioholics.com/av-receiver-reviews/onkyo-tx-rz70

I've been getting numerous requests to test the Filter 1 vs 2 settings for Fs = 44.1kHz (CD sampling). As a result, I set up the test to compare. Filter 1 - Marantz "audiophile" sound tuning recommended for music listening Filter 2 - Bench Test mode, designed to look better on the test bench...

Only in bridged mode and that's the case for most amplifiers when you bridge them.

Yes I tested BTL and don't recommend it IF the nominal impedance of your speakers is 4 ohms.
