Preamplifier that supports 3D movie

Marantz AV7005.

Rotel RSP1570

If you have a dual HDMI output BD player, you don't need to upgrade yr current preamp.

Just send one HDMI to the preamp and a second one direct to the display.

The cheapest I have seen in my region (Asia) is the Pioneer BDP-LX55 which retails for less than US$400 bucks. Probably cheaper in the US. The Samsung equivalent is not available here.

I use an Oppo 95.

Thanks for the information. I think I have some idea about preamp now.

Here is another question regarding projector screen.
Using Da-lite 106" (diagonal) fixed frame screen as an example, when I search for them on Amazon, most of the screens are $1k+, while on bhphotovideo.com, most of the screens are in $500-$700. I doubt that for the same product, the price difference will be this big. So I am assuming there must be some differences in the screens they are selling.

My questions regarding the screens:
1. What specs should I look at for screen? I know gain is one of them. Is a gain around 1.0 (or slightly above 1.0) the best for a HT with no (or maybe a little) ambient light? I have read projectorcentral.com and know something about screen gain and projector throw distance, etc.
2. What other spec should I look at for a projector screen?
3. What are the good brands? Da-lite?
4. What is a good place to buy the screen?

Thanks!

You can try AVSForums.com They also have an online sales department.

The main problem is that active 3D projectors require as much brightness as possible

Have a look at the Dalite HP screen. If you can fit your projector in the right area (i.e. zero offset pointing directly at the centre of the screen), it should give you around 2.4 gain.

The downside is that higher gain screens tend to have a smaller viewing cone, so the gain tapers off when you are off axis.

Which projector are you using?
