Whether wireless home theater system is preferable over conventional system?

No, wireless is NOT preferable...for two primary reasons.

First off, the nature of the way a wireless speaker operates doesn't make them wireless for practical reasons. To use a speaker wireless, the speaker has to have an amp built in. To run that amp requires power. To provide that power, you need do one of two things...either keep pumping batteries into the speakers...or plug them into the wall. The vast majority of people don't want to keep spending the money on batteries so they plug them in. If you plug them into the wall, you just ran wires. And if you can run a power plug, you can run speaker cables.

The second reason wireless is inferior has to do with quality. There simply are no high performance wireless loudspeakers. You will never find a single high performance theater spec'd with wireless products. There are always bandwidth limitations to a line of sight wireless product and this is the last thing you want.

There are very few spots that if you think and plan, you can't get wiring to. It is worth the extra effort. Wireless HT systems are usually "line of sight" so the wireless conection might fail when something interupts the beam. Your usually better off getting a hard wired system. Ya, surely wireless home theatre system is preferable over conventional systems. As the major reason is "Wireless" so that you can place or shift it anywhere in the house rather than having a wire one and all the hassles of shifting the wires everytime and sticking it on the walls and making dirty.

Not to forget that wireless home theatre systems may be quite costly as compared to normal home theatre systems.
