This is a great part of your home audio system should you decide to hook your computer or other device with a minijack plug in to it. A good long cable (other lengths are sold both in a M HP-10 and in the THX series). If you are unsatisfied with your current speakers, and have a good hifi system, but lack the digital connections such as S/PDIF out or Optical on your system, this is the way to go.
