The Mrak levinson no 326 is the closest that comes to these specs. I think this also matches GranteedEV's specifications as it does nothing but take inputs and reduce noise. I think i will go with this one.
1) But i have a doubt that if i add multiple electronics wont i be introducing noise in the final signal that will go to the speakers?If so what measures should i be taking to reduce such a noise?
2) Also the mark levinson preamp has xlr inputs so are they digital or analog?Will I have problems connecting them to a pc? Is this the correct choice i am making?or would i ultimately have to go with RCAs
3) When i use multiple electronics like source,preamp,room correction,video processor,amp how exactly will be the connections be i.e what will be connected to what (please explain this to me like i am a 6 yr old just so that i can get a fair idea)?
4) How can a power conditioner help me reduce noise and give me a clean noiseless signal? can u suggest me some of the best
5) How would i connect a ps3,xbox,wii through xlr?
Those specs by acudeftechguy were exaggerated joke specs, they weren't meant to be taken seriously. Noise below a certain level shouldn't be a concern. If the noise is humanly imperceptible, you don't have to worry about it. I wouldn't worry about noise if I were you.
That mark leveinson pre-amp isn't right for your system. It's a two channel, analog-only stereo pre-amp. You will not want to use that for a home theater.
The way to wire the setup depends on the components you get, of course. First you have your source (blu-ray player, nintendo, turntable, etc.) which you will want to connect to a preprocessor. If you have room correction hardware, my understanding is that you will want to place that between the source and preprocessor in the signal chain. Up to this point you should be using HDMI cables only, unless your source does not have HDMI. Now you need some line-level cables to connect the preprocessor to your amplifier, like RCA cables or XLR cables. You connect your amplifier to your speakers using some nice thick speaker wire (12 or 14 AWG) and you have your audio connected. If you have a video processor, you will connect that to your preprocessor's output using HDMI. Then you connect your video processor to your projector, again with HDMI cabling.
There is probably more than one way to connect all this high end stuff together though, since so much of it has so many inputs and outputs. Anything you buy will come with documentation explaining the recommended sequence of connections, and might give alternate suggestions as well.
As far as power conditioners go, that is a scam for audio. Do not get a power conditioner for the sake of improving your sound; it won't. I'm guessing the same is true video, but I don't understand the video side of things as well. A power conditioner is useful for the convenience of bringing a lot of power connectors to your equipment rack, but that is about it. If you want to protect your equipment from power surges, you should really do that at the breaker with some good protection, so it protects the whole house, not just the home theater room. For all this home theater stuff, you are going to need an electrician anyway, so have him put in some surge protection at the breaker while he is there.
If you are going all out with your home theater, I would get a bunch of heavy-duty, rack-mountable UPS units, and skip power conditioners.
