The Rega Planar 1 Plus has a built-in Moving Magnet phono stage, which means no additional box/cables for an external phono stage. The Planar 1 Plus has Rega's RB110 tonearm and a Rega Carbon MM cartridge.
Connect the Planar 1's line-level output to the A2's rear panel input using the included RCA to RCA cable and viola, the A2 speakers can now play your vinyl! There are no extra cables to buy and visually the cable count is quite a bit lower than most.
The A2 comes in two versions: The A2 ($199) powered speaker, and the A2+ ($269) which adds bluetooth connectivity so you can connect your phone or computer to it and stream music. The A2 does not have a remote - you control the A2's volume using a knob on the back panel.
