Yamaha 665 vs 663 Opinion Needed

[callas01]

Forsberg, I was looking at This and the 665 is not as powerful as the 663, according to them they are not the same with 2 extra HDMI inputs, go about 3/4 of the way down and they compare the 665 and the 663.

I am not saying the 663 is the end all- be all of AVRs but there are significant difference to the power and wattage outputs, according the the article.

I totally agree, as it seems they sacrificed some of the power on the 665 for some additional features instead. Reminds me of the 805 vs 806 debate I've seen here. Especially because the weight difference for the 663 is 8 lbs heavier. In the end, power appears to be a big issue here since they think the internal op-amp doesn't have enough kick to power up an external amp properly before it starts clipping. I was looking at this for the pre-outs and getting an Emotiva or Outlaw amp. Finally, their calculation showing a significant drop in wattage per channel is what finally scared me off. I'm going to look around for the 663 or something like a Pioneer Elite, Denon or Marantz that has a good price point.

Thanks for the article!

yeah, no prob, the other thing that i saw was that they were talking about pre-outs on the cheaper receivers don't work as well typically either, so it may be worth it to get an elite or sony es or denon 2308/09 and then adding an external amp so that you don't run into the clipping and distortion issues within the AVR.

Just a thought, I think that is what I am gonna do down the road, get a better receiver then an amp...

Check out this deal of the week, could prolly hold off on an amp for a little while as this should power you pretty good to start?

Yep, that is what I am doing now......starting my research and trying to save enough $$ so I can get both the receiver and amp at the same time.

I really hate upgradeitis......and then there's the WAF factor too.....

YEP, I am on restriction for a little while from buying anything.... Other then BDs of course, just no equipment..

I got it from this article from Audioholics:

http://www.audioholics.com/education...nology/trading

In the section "So Watts The Problem"

About half way down it states, "They usually don't put decent op-amps that have enough output to drive an external power amplification to its full potential without the internal preamp of the receiver first clipping and going into gross distortion." Am I wrong to interpret this to mean that the newer receivers that have sacrificed power for more features to mean they lack the power to properly feed an external amp? I don't want to mislead anyone, including myself.

Forsberg ~ If you are using an external amp with A receiver All the receiver is doing is sending the amp A signal ! It is not sending Watts to the amp !

Yeah, I see what you mean and you're right crazy...this is why I am asking all of these questions now, so I can get all of the stupid ones out of the way first, as the world of pre/pro's and external amps is a very new one to me....LOL!........mmmm.......but isn't this statement above an issue of concern when shopping for a receiver to be used as a pre/pro with an external amp? It left with me with a funny feeling about any receiver I am looking at...

No question is stupid if you are learning about something you don't know .
My 663 is by no means TOP OF THE LINE & it does a great job within my setup.
The issue above I would think would only be A concern if say you are running the amp on the front 3 & running you're surr. off the receiver !
Right know my 2 amps are running my front 3 speakers & my surr. & surr. rears are running off the receiver & I have no issues with CRANKING it !!!
