I can confirm that this worked as I just purchased an RXV-473 for RM1900. Updated the firmware to 1.64. Hooked it with Mordaunt Short LR and C speakers with Kenwood Active Sub + old Onkyo surround speakers. YPAO callibration was very well down. But I custom fine tuned it a little. Few comments and help needed on this unit as this was my first Yamaha. I have 2 Denons, 1 sold and one taken away by my brother.

1. The on screen display's graphics are really ugly. Anyone agrees with me?
2. Maybe I haven't get used to Yamaha, but it seems not to automatically detect 2.1 or 5.1 from the source. previously from my Denon, when it received 5.1 channel (AC3/DTS/TrueHD/MasterAudio) it will automatically switch. But for this RXV673, it kept the previously used setting, eg when I was playing stereo, once I changed to another source (on and off the unit), it will retain whatever scene I was using for all stereo playbacks. Similar goes to 5.1 channels. I have it on Standard Movie, but when I playback (also, turned on and off the AV, coz play it next day), it will retain the previous scene, in which this time, I played a 2.1 only movie, but it went to surrond decode. Anyone knows a way for it not to remember previous scene but to just automatically use the source signals?
3. The most annoying would be this. My unit is connected with Bluray/PS3 and a Media Player. When I was listening to music, be it via the Media Player or USB (front), it worked perfectly while the TV is turned on. To conserve energy, I turned off the tv and viola, the player stopped to output any music. The red HDMI out will be blinking. Only after I turn the TV back on, it resumes. Tried HDMI control/HDMI passthru, nothing. Any advice?

In overall, i would say that this unit performed fine. Love the Dialog volume and lift increase. DRC works well too to keep the sound in an acceptable level, but I turned it off The LCD font is kinda large and ugly though

Thanks in advance for any help.

Duh...looks like I'm stuck with the constant need to turn on my TV, even when I'm listening to the radio. The only way would be to go into pure direct. but that bypasses the subwoofer. Bookshelf's bass can't compare to a sub. What a waste of energy....haiii

Same. The sound will play but crackled.

That should be Aquos Link on my Sharp TV. I don't think I set it to on, but let's see tonight. I'm getting a 15m LAN to test out the network capability today though.

Aquos Link is off by default. HDMI control is off by default. No improvement.

Tried again with the TV not in standby mode and it worked. Guess the standby from the TV is the culprit.

On internet radio, it worked well. WiFi remote in android worked flawlessly as well (need to manually input IP if you set the amp to static IP which in this case I did). But it doesn't seem to detect my NAS. Only able to detect the Thompson router on both manual and auto ip. Same thing happened when I tried to 'see' my NAS from PS3. Couldn't detect. But media player sees it well though..

I have the 673 for like 2 years now. Amazed that there's an upgrade now, 677 . Anyway, it was hooked to a bunch of mixed speakers, namely Mordaunt Short Bookshelf Fronts (MS1), Mordaunt Short Carnival Middle speaker, re-used old Onkyo mini surround speakers, and an old kenwood sub (which sounds pretty ok). Been keen on an update, but bumped into a sale on the 160 series (SPK160BL). Selling less than RM2k. Any of you guys using this and how is the performance? I personally think that it'll better my current configuration, but let's hear you guys out. Cheers.

Old vs new perhaps? Or use da mahney to get PS4 better?
