A friend is going to buy a unexpensive HT setup, his budget is about 600$. Here it is: - Yamaha RXV-430 - JBL SCS-135SI speakers http://www.jbl.com/home/products/pro...Id=SCS&sCatId= ¿Is there better options of speakers for this receiver and for this price? If that JBL speakers are good ones, ¿it's worth de difference of money to pick the SCS-150? I have about two weeks to advise him before hi buys this package. Thanks.
