Have you ran YPAO with more than 3 points? If so, check the results, they're completely off. Have you tried using AI with Netflix's Atmos? You should hear the dialog leaking from the front heights.. There are many more bugs and the sound compared to any other AVR such as the Onkyo RZ50 or Denon X4700H, is very disappointing, according to many user reports.
Here is an impression example, from a user after 2 months of usage (auto translated from by Google):
We connected the A8 in a composition of 7.2.4 There are 2 subwoofers and 4 speakers in the ceiling. We connected 3 different sources to it. Projector and TV.
We performed a basic calibration for initial measurements and settings. And here we encountered a first problem the distances of the speakers came out wrong.
The calibration was performed perfectly according to the book. We did 3 more tests and they all came out wrong. In the last test we used a microphone Of the 5200 without change. [After 2 updates of - YAMAHA the problem is solved but not in all cases] When calibrating
For more than 3 locations always one of the channels responds incorrectly [not always the same channel] There is a BUG Report to YAMAHA and they are aware of the problem. Currently the solution is to calibrate to only 3 locations.
I wrote that it was a short impression and I will explain. There are 2 main reasons.
1. Currently the device is not really ready for a real and comprehensive test. The delay in updating HDMI also hurts things and companions [HDCP 2.3 And its capabilities like - EARC] all these do not work and limit / impair the working capabilities of the receiver. According to the manufacturer should be updated by the end of the year. We also could not test the AURO 3D and it should be updated in the coming weeks.
2. There are some serious BUGS that impair the working capabilities of the receiver. [We reported and the manufacturer is aware of the issues and is trying to reach a solution as soon as possible . [But some still exist for almost 90 days without a solution] The worst BUG is that the receiver is not capable decoding DDP and this means that it is not possible for ATMOS via DDP and since this is currently the main way from STREAMING it serious problem .
Another problem in the same context is if you try to use AI while using ATMOS DDP the sounds do not come for the right speakers [for example the CENTER comes from the ceiling] some things happen when the ATMOS DDP is running.
1. The audio just disappears / stops working. 2. The receiver freezes and stops operating, which requires disconnection from the power supply and restarting. but no, The settings are always saved. YAMAHA admit that the problem exists but in their opinion it only happens with the use of HBO MAX. But this not really the situation. This has happened to us with almost every source and every input on the receiver. [We tried them all] Another problem is that there is - LAG
Seriously when trying to watch DV but - YAMAHA claim that it will work out after updating the HDMI. Another thing is
That there are explosion sounds from the speakers [POP] at different levels in the transition between the different sources. YAMAHA is aware of all the problems that I mentioned and at least regarding some of them they announced that they are trying to reach a solution. After trials there are a number of temporary ways / solutions and workarounds to try to get to the desired audio but at the moment it is in detours and not always accurate. So right now everyone is waiting for YAMAHA to come up with solutions to at least some of the problems.
An example of what happens in a receiver while using DDP is how the audio just disappears over and over again and this is just one problem.
In light of the whole situation as it is at the moment there was really no point in conducting a full examination and review. We made 2 brief comparisons just out of curiosity
One [blind] comparison was with YAMAHA's A3080 at only 7.1 channels. There were 4 present and 3 did not notice
In difference and one thought the A8 sounded better [this is the friend who purchased the receiver] We all agreed that the frequency management system
The lower performs better but still not well enough compared to other manufacturers. The second comparison was compared to the RZ50
The new ONKYO and here everyone agreed that the RZ50 sounds better and its price is less than 50%. For the calibration system of - DIRAC
There is a large part in the differences [there is nothing to compare in the results] but for any serious test / comparison one must wait for the good performance of the A8. [Obviously any comparison of audio is completely subjective]
GENE from AH has decided not to wait any longer for YAMAHA and will soon publish his test results regarding the A6.
All the information is definitely not good. He allowed YAMAHA more than 60 days to comment on how they were going to solve the problems
The mains he found [absorbed a lot of fire on the long wait] and now decided it was time. We will wait for the results including the various measurements post Scriptum. The purchased receiver was returned to the store before 60 days.
