This should also be what is coming out of the HDMI all else being equal. 5.1 isn't a big loss these days as there are few titles that are encoded for it anyway. And you have to have a room and furniture placement to make it effective anyway. Here's a crude drawing of what it would look like : Left front Center Right Front Subwoofer Chair/couch Left rear Right rear Left back Right Back Usually the left and right backs are closer together. With the right soundtrack 7.1 can be mind-blowing. But as I said, little uses it yet.

IOW, you got caught in Job's reality distortion field :) But, despair not, you bought a good computer. For instance, if it's offered with 3GB of RAM, it's not because, like Dell, Apple is trying to get rid of old RAM, it's because the CPU's architecture offers, just like the i7, 3 memory channels. So, I would, of course, switch my computer for yours any day, that's not my point. My point is 1) You could have bought the same computer in the PC world for much less, hardly more than half the price. Like for all Macs, teh value of your computer is roughly 60% of the price you paid. 2) In the PC world, whereas Apple offers none, there are a thousand alternatives to fill the gap inbetween the Mini and the Mac Pro. You can even have the PC you need built to measure. Which means that if specs susch as the Mini's don't satisfy, you don't have to go way overboard and buy a Pro. So, when I see M&Ms being ripped off and then bragging about how good Apple is doing at each and every quarter, I can't help but to wonder how deep human stupidity can get. As I already explained, the totalitarism of Apple is even worst than Microsoft's. It's very representative of the kind of industry that brought our economy down. I'm not suggesting you sell your Mac tomorrow as if it was the devil incarnate, but it would be nice if somebody like you stopped bragging about the value of the Mac and maybe thought of your next computer as a PC with Linux.

Fiber optics conduct light, metal cables conduct electricity. It's a pretty simple distinction. -- "I wear the cheese, it does not wear me."

They carry electrical line level analogue sounds. They use the external sheathing as the second conductor. No stereo system uses RCA plugs to receive digital signals. RCA plugs are to receive analogue line level input/outputs and it is one channel per plug. If you have 2 copper conductors that are sheathed, then it isn't "coaxial" cable per say. real coax and fibre carry bitstreams (digital) which are converted into a number of discrete analogue line level outputs within the amplifier's computer section before they are fed to the amplifier's analogue amplifier section. As a digital data stream, those cable are able to carry multiple discrete channels on the same cable. You cannot do that on plain old copper (with RCA or sony) plugs. The only "copper" that could carry digital sound would be an ethernet cable if your stereo is so capable. In telecom, "copper" is very very different from coax. It doesn't refere to the materials used to make the cable, it refers to a electrical philosophy. Coax is not good to transfer electrical power. It is very good at transfering RF (electrical power at very low volt/watt but high frequency). Copper is better at transferinfg electrical power, it is not very good at transfering RF because it is so easy to get interference. |
