5.1 under 4k?

You need to provide a little more info as to what you expect from the speakers and some examples of what you have already heard. There are so many options in your price range, any responses would just be random guessing.

"I could not sell this level to my customers. I am a perfectionist and only interested in the best.Even good never will be good enough for me!"

For someone who claims to be a perfectionist, you're slipping.

"I COULD NOT SELL THIS LEVEL TO MY CUSTOMERS. I AM A PERFECTIONIST AND ONLY INTERESTED IN THE BEST. EVEN GOOD NEVER WILL BE GOOD ENOUGH FOR ME!"

Now its OK.

Jeffpell,

I like Monitor Audio speakers myself. I think they would be a very nice upgrade from your Polks. What I like best about MA is their tweeters. Even though they are metal, MA does a great job in getting them to sound refined and not harsh.

Another brand you may want to look at is Definitive Technology. I wouldn't use them for music, only for theatre. They aren't too expensive and some models come with a built in powered subs. That will take a big load off your Marantz.

There may have been some confusion in my last post. I was under the impression that the OP was getting these speakers for theater only, not music. My Deftec recommendation was meant to be taken in that context. If the amp is going to be a Marantz receiver, I think the system would benefit greatly from having the built in subs.

As far as MA goes, I think they're great. I've owned both brands in the past and much prefer the MA. However, given the application and the OP's current equipment, the Deftec is just another option he may want to consider. Also, when it comes to 3d imaging, every piece in the system contributes. If any one piece is not good with 3d, you won't get it; even if all the other ones are. It's really just a matter of what is important to the OP. He has to listen to it, not us.

I think you made some good choices. I had the 2nd generation Silver S8's myself and really enjoyed them. I'm sure the newer version that you have will sound even better. Also, I think it was a very smart move to go with the better centre channel. I'm not too concerned with HT, but the one thing I see quite often is that the centre channel sometimes has a hard time keeping up with the main L&R channels.

As far as a sub goes, I would just wait a while until your speakers break in and you have a chance to get to know them. Doing it that way will make your sub selection easier.

You have pre outs for all of your channels. You can get a separate amp of any of them and still use the amps in your 7007 for any of the channels you don't get amps for. For example, you can buy a 2 channel amp for your front left and right speakers and still use the 7007 for the center and surrounds.

"How do I tone down an amp to not damage the newly purchased speakers?"

That's not a problem. You adjust the gain for each channel using the preamp in your Marantz just like you normally would. The best way to not damage your speakers is to listen to them. You should easily be able to hear if something is straining. If it doesn't sound right, turn it down.

Jeffpell,

You don't know anything. Of course the picture is no good. Its only a 2D picture. 2D picture is horrible. You need the right equipment to make 3D photo. Only wenn you do this will picture be 3D and it will sound OK. Until then, 2D picture only!!
