Greetings to all PDVD members! Need your advice on this simple matter...hope it's not too much to ask.
I own an LG BD390 blu-ray player that I brought with me from the US, which has a 7.1 channel analog output. I'm hoping if anyone here could recommend what speaker/sound system would work best on it and how much would it cost me? With a Panasonic 46U20V plasma to accompany my BD390, I felt that the only thing that's lacking is a set of speakers that would bring out the best audio in the blu-ray movies that I'm watching. 
A friend of mine was thinking if I could just make use of the 5.1 HTIB speakers from an old Sony DVD receiver lying around on my father's house...para hindi naman daw masayang at magamit ko pa sa existing blu-ray ko. Is that even possible? 
I don't want to end up buying a new blu-ray player/receiver...gastos na naman if ever! 
Pardon my ignorance on the subject. I hope someone could enlighten me. Thanks in advance!
