Hi Guys, happy to have found this thread though I don't own a Onkyo 805... but I just got my Onkyo TX-SR 505 two days ago... and I SUFFER FROM THE SAME PROBLEM...
I also experience slight, very slight delays in the audio... it is just not right!
The "bad" thing is I have an old-fashioned "good old" 32" 16:9 CRT, which I am still happy with. So there is no digital image processing going on, hence the picture is as fast as it could be. I have my DVD-player directly hooked up to the TV (via SCART-RGB), bypassing the Onkyo. Noticed the delay then yesterday evening the first time... monitored a while to verify there is an issue, then checked the audio delay setting to find out there were set to 20ms for my DVD-Optical-input and to 40ms for my analogue stereo input from/for my laptop. Where did that come from by the way (preset?) ?
OK, I corrected this to 0 ms, but alas, the situation has only improved slightly.
I can still notice a very slight delay, as mentioned it is very slight only, still noticeably... especially if you watch out for it. I would "guess" 20-40 ms, played a little bit with with sync options on the playback-software on the pc, I can make audio play earlier with this.
This receiver is only used for video and music playback, still I noticed the issue! And still I notice it is still there, even though audio delay is set to 0 ms and it is only video material I am watching and listening to (and regular audio, i.e. MP3, CD as well)..
Seems for me like the whole TX-SRXX5 series is affected.
Any sugesstions? I am wondering if I should return the device and get something equivalent (300 Euro price range, I am from Germany), which doesn't has this problem... but how to be sure it is not affected by the same problem before I get another receiver? What about the current or one-generation earlier YAMAHA's? I know they have a lot of DSP's so I am not optimistic.
Still, the Onkyo 505 sounds excellent, Multi-Channel as well as Stereo, even it is budget-range, and I would NOT be happy to return it, but I am not sure if I can get along with this problem.... DAMN...
The problem is I am one of those persons that will probably constantly watch out for sync issues, even it is neglectable... I wished I had checked the audio delay settings directly when setting up the thing, then I would probably have never noticed there is an issue.
When I turn on the TV simultaneosly I notice this echo effect... sometimes more, sometime less, depending on the video material.
Can I learn to accept the problem?
Just tried fiddling with the speaker distance setting, but I found the stereo sound to be not half as satisfying previously. Best sound is produced if the realistic values are entered.
When I change the fronts for example to maximum distance, Onkyo automatically adjusts the rest accordingly. But afterwards the sound is not as good as previously....
What do you guys say and what do you recommend? I am not sure myself to be honest...
What about the current YAMAHA budet line... Yamaha RX-V461 especially... anyone knows if that thing has the same problems...
And what do you think quality/performance-wise... better or worse than the ONKYO 505...??
Thanks a lot in advance and best regards,
