The Magnepan LRS (and LRS+) are famously revealing planar-magnetic speakers — and famously hungry. They present a roughly 4-ohm load and reward high current far more than raw wattage, so the amp matters as much as the speaker. Here are amplifiers that consistently get the LRS singing, from value powerhouses to audiophile favorites.

Buying tips
- Prioritize current and 4-ohm stability over advertised watts — the LRS need grip, not just numbers.
- Aim for roughly 100+ watts into 4 ohms for comfortable dynamics in an average room.
- Bridging affordable power amps (e.g., a Schiit Vidar pair) is a popular way to add headroom cheaply.
- The LRS roll off in the deep bass — a fast, well-integrated subwoofer pairs beautifully and eases the amp’s job.
- Give planars some space from the front wall and toe them in — placement changes the sound as much as the amp.
