First of all Welcome to the Shack!

What is your budget as the Onkyo is about $300 the Yamaha is $400
I would not bother with the Pioneer as there have been some issues with there receivers as of late.

In all seriousness if you can push your budget and get into the Onkyo TX SR706 you will be getting a great receiver for the money. Onkyo right now seems to have the best bang for buck. If you must stay within that range then the Denon 1909, Yamaha 663 or the Onkyo 606 will do a fairly good job (5 or 10 watts difference between them is not really noticeable).
How large is the room your using this in?

Again, thanks for you time.

My movie/music room is about 4x7 meters.

No problem, Your room is not huge but its not small either.

I think the onkyo 606 looks good in the specifics, but its really ugly I think, and I have to place it ontop of the tv bench under the projector screen, so it must look kinda nice! Or is it really stupid to think like that?=)
Thanks

Looks are important but keep in mind also that some of the nicest sounding speakers can be some of the ugliest. If thats an important one and you like the Yamaha 663 then there is nothing wrong with it and I would say a decent choice.
I do believe that it has pre outputs so in the future you could add and external amp to power your mains.

Marantz makes a good receiver just make sure it has the latest audio decoders (TruHD and DTS Master audio) and ideally has pre outs for future external amp connect ability.

 

[tonyvdb]

Go with the Marantz 5003, Its got everything you need and could really want. It even has a 12DC trigger so if you have a powered screen or other device it will turn it on as well.

You can always try it out and if you dont like it the just return it to the store. I still like the Marantz better but it boils down to what you like not what others like. The HK may be a bit underpowered but they rate their receivers differently than other companies just to add some confusion to the mix.
