    • Speaker Cables with Banana Plugs: If you know the lenght of the cable you need, this is the easier option to connect your speakers with your amp.

    • Banana Connectors and Plugs: If you chose the cables without connectors option or already have some cable around, pick the banana plugs separately.
  • Vibration Isolators: IsoAcoustics isolators are our favorite isolators but you may find more affordable options too.
  • Acoustic Panels and Treatments: Your room is as important as your stereo equipment so acoustic treatments goes a long way in improving the overall performance.
