Is a 10w power difference noticeable?
I just bought a Yamaha rxv379 to power my home theatre/entertainment centre. Set up is fairly average - a 5.2 Polk audio rm6570 speaker system, appleTV, Xbox, digital cable TV. I was powering it before with a 2.5 year old Pioneer VSX 522 that just stopped producing sound one day and since it was out of warranty, well, you know the deal - too expensive to fix so you buy another.

As for the rxv379, I'm still in the process of monkeying around with calibration and configuration but I am noticing a slight lack of "oomph" when playing music. On Netflix movies its got more than enough punch for my fairly small (700sq ft) apartment. But music "seems" to play at slightly lower levels than with my Pioneer. Not radically so but somewhat. To play it loud I need to push it up to around 80 - 85. It's got a max vol of 96. Right now the only way to test music is streaming from my laptop to my apple TV using the mirror function. I could bluetooth pair as well from my laptop/phone or tablet but haven't tried yet. Not sure if wireless signals mean a degradation in sound quality or power. Since this thing doesn't have a USB like my last, I can't plug in a phone, ipod etc.

What's bugging me is I could have got the rxv479 for about $58 more. The 379 is rated at 100w 1ch driven, 70w 2ch. The 479 is rated at 115w 1ch, 80w 2ch. At the time I didn't think that an extra 10w would be missed - and I'm not sure now either. The sales guy at the store didn't seem to know either. The 479 had a bunch of wireless feature I didn't think I needed given that I have apple TV which allows streaming from any of your apple devices. Hence why I decided to save some $$ and just get the 379. Now I'm considering returning it for the 479 if it'll give me a power boost.

What are your thoughts on the extra 10w? Worth $58 or will it be hardly noticeable?

No, I doubt the 10W will be noticeable.

You would get the RX-V479 for its additional features such as 2 more HDMI inputs, networking, WiFi, Airplay, internet radio, Pandora, binding posts on all speaker terminals plus the ability to use your smartphone as a wi-fi remote.

All of that would be worth the extra $58 to me.

Never buy bottom basement models from any manufacturer. They'll get the job done if you have lowered expectations.

Odds are pretty good that you don't turn up the volume all the way, that's where the extra 10 watts would make a difference. Not a big deal.

I'd bring back the 379 and step up to the 679. You can also get a higher end refurb/"B"stock model for around the same price as the 679.

The v479 has better amps than the v379. A noticeable difference. Yamaha isn't known as beef city
when it comes to power. That and the network etc. no brainer for $60 more.

50 watts would not even make much difference. It takes roughly double the watts to get 3 more dB. So even if you were at your 70 watts, 10 more watts would probably not even get you 1 dB more output.

You would never notice the difference assuming the ratings are accurate of 10 watts apart
