My best speakers are a set of handpicked JBLs that I purchased about 10 years ago. They were massive for a 27" tube tv heh. I have a set of Polk rm510 purchased 3 years ago when I moved back into the US. They are tiny in comparison, but with very nice sound, and the sub has its own remote. The Denon set I just bought a couple months ago is just pathetic. I have no clue what I would use them for. Maybe connected to the pc downstairs... Lol.
Here's the thing with technology: when I purchased my jbl speakers, I got a jvc receiver. I think the remote alone still sells for over $150. Which sucks because I lost it when I moved to Spain for 2 years. Anyway. Back then, nobody had HDMI. The best and greatest for video was composite cables, and for sound, optical. This meant 5 cables between receiver and tv.
When I purchased the Polk rm510, I bought a 50v10 plasma, the speakers, the sub, and a yamaha receiver. There was no 3D available at the store. I don't think there were even hdmi 1.4a ports available on any receiver.
Now, I purchased the Denon hometheater in a box, which has 5.1 speakers and hdmi 1.4a for 3D, but it's junk. Only cost me $200, though original price was about $600. At $600, I'd kill myself. At $200, I still slap my wrist lol. It's better have been used to purchase a dual hdmi 3D bluray player or save for a new receiver.
The yamaha and jvc receivers work great, like brand new, why replace them? I have since purchased an sv472xvt led, a 55st30 3D plasma, and a 55lm8600 3D led, which I just returned yesterday. Since now I'm planning on having 2 3D tv's, I need to figure out how to spend the least amount of money and make everything work out perfectly.
In your setup, you need to connect anything that has 3D capabilities directly to the tv, because it's your only 3D compatible output. The tv then should be hooked up to your receiver through a coax cable. I will look for pictures and post them later, if allowed.
