Arcam Radia A15+ Integrated Amplifier w/ Bluetooth, HDMI eARC & Auracast

Arcam Radia A15+ Integrated Amplifier

The Arcam Radia A15+ is a modern, 80-watts-per-channel, Class AB integrated amplifier that unites hi-fi musicality with everyday convenience. Inside is a proven ESS ES9018K2M DAC for crisp, low-noise digital playback, while HDMI eARC adds seamless TV integration—PCM stereo up to 24-bit/192 kHz with rock-solid lip-sync. Next-gen Bluetooth 5.4 with Snapdragon Sound, aptX Lossless, LE Audio, and Auracast means premium wireless listening and simple headphone sharing. A tuned MM phono stage, front-panel headphone output, and stereo pre-outs for a subwoofer or external amp make A15+ a versatile hub for music, movies, and vinyl.

Why the Arcam Radia A15+

• 80W Class AB power with low distortion — Drives bookshelf or tower speakers confidently with 0.002% THD at 80% output for clean, dynamic sound.
• ESS ES9018 DAC built in — Hi-res digital playback with excellent signal-to-noise for precise, detailed listening from your TV and digital sources.
• HDMI eARC for simple TV integration — One cable from your TV delivers PCM stereo up to 24-bit/192 kHz with proper lip-sync for movies and gaming.
• Bluetooth 5.4 with Snapdragon Sound — aptX Lossless, LE Audio, and Auracast provide premium wireless audio and easy headphone sharing.
• MM phono stage on board — Plug a moving-magnet turntable directly in for quiet, accurate RIAA vinyl playback.
• Stereo pre-outs — Add a powered subwoofer or external amplifier to expand your system over time.

What It’s Great At:

• Music & TV on the same rig — HDMI eARC turns your hi-fi speakers into a true TV upgrade without a receiver or soundbar.
• Effortless everyday streaming — Two-way Bluetooth lets you stream to the amp or out to headphones for late-night listening.
• Vinyl playback — The tuned MM phono input delivers lively, low-noise analog sound without a separate phono preamp.
• Driving real speakers — 80W into 8 Ω (120W into 4 Ω) provides the current and control most living rooms need.
• Clear detail at low volumes — Refined power supply and DAC maintain clarity and separation when you’re listening quietly.
• System building — Pre-outs make it easy to add a sub or external amp as your system evolves.

Everyday Usability (quick wins):

• One-remote TV control — Use your TV remote via HDMI eARC for volume and instant audio switching to the A15+.
• Auracast sharing — Broadcast audio to multiple compatible headphones or speakers so everyone can listen together.
• Front-panel headphone jack — Plug in directly for private sessions without rearranging cables.
• Compact, premium chassis — Aluminum build with clean Radia styling fits modern furniture and runs cool and quiet.
• Simple input layout — Three RCA line inputs plus phono, optical, coax, and HDMI keep setup fast and flexible.
• Future-friendly add-ons — Pair with Arcam’s ST5/streamers or a better turntable later—no replacement amp required.
