Preamplifier that supports 3D movie

Thanks for all the replies.

Are 3D capable preamplifiers all new models?

I have heard that sometime you can get great price on last generation (i.e. the one before the current generation) flagship models, and since those models were designed/made as flagship products, you can still get great quality and probably they provide better quality/price ratio than brand new ones. Are there such 3D capable preamplifiers models?

I was originally looking at Lexicon MC-12, and then found out that it is not capable of handling 3D movies.

Thanks!

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!
