I will soon be getting an HK 320 and moving my four JBL n24s to surrounds for 7.1. However, I am torn between JBL ND310 towers and S38 large bookshelfs for my mains. The ND310s are about $50 less and come with free shipping from JandR, for a savings of about $100. Also they would match my N-Center. However, I think I would enjoy the S38's more. They would most likely be run off an Audiosource Amp Two or Amp Three. Any comments, or maybe some other suggestions for front speakers in the $200-$300 range? Thanks.
