Questions about : Sony HT-SS2300 Blu-ray Disc™ Home Theater System

[alfehdy]

hello

iam about to purchase
Sony HT-SS2300 Blu-ray Disc™ Matching Component Home Theater System
i read alot of positive reviews about it so i think iwill pick it

but i have some questions about it
i will be glad if u answer it

1- what does " Blu-ray Disc™ Matching Component " means ? is it mean that its originally not a blu ray system or ?

2- i read that the rear speakers arent wirless so poeple are taking about rocketfish system , what is it !! is it some kind of special speakers or what ?

3- i read some reviews saying that u can connect ur ps3 through HDMI cable to the reciver and a digital optical cable for audio from the reciver to the TV LCD , does that mean i will not connect HMDI CAble from reciver to TV
and what is the use of this cable since the audio i will be hearing is from the speakers not the TV

4- I reviewd this blu ray home theater system from amazon.com and i was about to buy it but i found a big issue which is the power Requirements.
since US uses 120V 60HZ , and since iam from middle east we use here 220V 50hz

please no body tell me to use voltage convertor because it doesnt convert the frequency too , and the frequency convertors cost arround 1000$ which is more than the double of the blu ray home theater price

so is there any chance i can get the same item from amazon by same specs i need ? any one got some experience about this issue?

this is the link of the item in amazon
