I've narrowed it down but...

If your primary use is for video, I'm not so sure that ultimate sound quality is all that important for a couple of reasons- first, I think we are primarily visual animals and so the video quality dominates our sensory expericne.  Second, I don't think most video content providers put much of a premium on the audio portion of their content delivery.  I will tell you that my Marantz SR 5006 sounds WAY less powerful than its 100 wpc rating.  If I had to do it over again, I'd have gone for more power. 

I ordered the Yamaha RX-A740 Advantage receiver and BD-S677 BluRay w/SACD universal player from A4L. Looking forward to my first new pieces of equipment since the early '70s.

Opps! My fingers were typing unconsciously, I ment Aventage not Advantage.

let us know how everything turned out...I shopping for an av receiver too.
Not sure weather to get newest 2.2 hcd 4 k or not

I ordered the Yammie rxa740 and bds677 on Wed morning and received it on Fri morning. Fast shipping from A4L.

I upgraded software on both units to the latest available from their website using a usb thumb drive.

I've begun setting it up using their mic for a 3.0 system with the L/R speakers bi-amped (rear speakers and sub will coming later) The sound is quite boomy. I looks like the shown frequency response has big bass peak and mid-bass peak. Wonder if I should manually adjust the response so I'll have the play with it to tweak the sound, but I work today and tomorrow so it will be slow going.

Tough my center speaker are 6 ohms and L/R are 4 ohm, I tried the 6 ohm impedance setting but it looses dynamics, so switched it back to 8 ohms.

Over all sound is clearer and more dynamic than my 23 yr old Denon stereo receiver. I'm liking it.
