Now that I got rid of my bose satellite speakers and replace it with a pair of decent NHT sb3 and sc2 center. Should I upgrade my sony DE-895 (hit-list here in the forum)which it has no problem powering up these speakers but I could be missing some sound. I was told and read here in the forum that these speakers needs a lot of power juice. Do you think I need one of those suggested receivers here like HK430/630, Yama HTR5790/1400, Marantz or Denon? I'am using a mission 77ds as a surround and a cheap vidsonic subwoofer. So, basically my receiver has enough power and the sb3 and the cheap vidsonic subwoofer provide enough boom. But, if you have to choose between a new receiver and SVS PB10-ISD/HSU stf-2 subwoofer which one would you choose? I can only afford 1 purchase. Thanks for the input.
