Key Features
The Arcam Radia SA45 Streaming Amplifier and JBL L100 Mk2 Classic Standmount Speakers Hi-Fi Bundle is designed for listeners who want a powerful streaming amplifier with the scale and character of a large-format JBL Classic speaker. The SA45 delivers 180W per channel into 8 ohms from Arcam’s Class G platform, with balanced analogue and digital audio paths, ESS Hyperstream iV DAC topology, and a linear toroidal power supply.
The JBL L100 Mk2 Classic speakers use a 3-way design with a 12-inch cast-frame Pure Pulp woofer, 5.25-inch polymer-coated Pure Pulp midrange, and 1-inch titanium dome tweeter with acoustic lens and waveguide. Their 90dB sensitivity and 40Hz-40kHz response give the system strong standmount presence, while HDMI eARC, MM/MC phono, dual subwoofer outputs, Dirac Live, AirPlay, Google Cast, Spotify Connect, TIDAL Connect, Qobuz Connect, Roon Ready, UPnP, and USB media support TV, vinyl, and streaming.

The SA45 provides the JBL L100 Mk2 Classic speakers with a powerful, versatile foundation, combining 180W per channel Class G amplification with hi-res streaming and extensive connectivity. Its power gives the JBLs plenty of drive for dynamic music while helping maintain control through demanding passages and higher listening levels. Digital and analogue inputs accommodate a wide choice of sources, while the Arcam Radia app and supported streaming platforms simplify everyday listening. Together, the amplifier and speakers create a system that combines convenient modern access with substantial stereo performance.
The JBL L100 Mk2 Classic speakers bring scale and physical presence to the bundle, complementing the SA45’s powerful amplification with a large three-way design. A 12-inch Pure Pulp woofer provides substantial bass weight, while the dedicated 5.25-inch midrange helps vocals and instruments remain clear and distinct. A titanium dome tweeter handles high frequencies, completing a presentation designed for spacious, energetic listening. Paired with the SA45, the L100 Mk2 can deliver the room-filling character associated with JBL’s Classic range while retaining control and detail across varied music.
This pairing gives you the distinctive character and appearance of the JBL L100 Mk2 Classic without sacrificing the convenience expected from a modern system. The SA45 adds HDMI eARC for TV sound, hi-res streaming for everyday music and phono inputs for connecting a turntable. Dirac Live helps tailor the system to your room, which can improve balance and integration at your listening position. Dual subwoofer outputs also provide scope for expanding the system, giving you a flexible setup built around the JBL speakers’ substantial scale and traditional hi-fi presence.
