I'm upgrading family room with new flatscreen, etc. I'm not going to do surround sound, but want a big upgrade to music. tThe current plan is Polk 703 (no room for floor speakers) and marantz 6008. The questions are:

1.do I need a sonos with bridge to run music to the marantz. This is very confusing as I want to send music from ipad, computer etc.

2.  for this range of equipment, any other options that should be considered.

Thanks
