I am soon to buy a New Stereo system and am over looking Infinity Beta 50's VS Klipsch SF-3 speakers. I am considering buying one of these different sets of speakers. My mind is open and would consider other choices as well. I will need a complete system including receiver and CD player as well so any suggestions would be appreciated. I gravitate toward Hard Rock and Metal and will be using this system to listen to music not to listen to movies. Please let me know what you think?
