SoundUp is a small mono amplifier that packs a punch with 100 watts of power at 3 to 8 ohms, making it suitable for most analog speakers. Unlike pricier alternatives such as the Bluesound Powernode Edge, which starts at $749 on Amazon, SoundUp lacks features like WiFi, Apple AirPlay, or stereo output. On the bright side, you can connect two SoundUp units together for stereo sound, and it utilizes a Class D amplifier for efficient performance.
