Halo A21+ — Power You Can Feel, Control You’ll Love
The Parasound Halo A21+ delivers commanding power with effortless musicality. At 300 W per channel into 8 Ω (500 W into 4 Ω), and up to 1,000 W bridged, it drives any loudspeaker with authority while keeping the sound spacious, controlled, and fatigue-free.
Based on legendary John Curl’s circuit design, the A21+ refines Parasound’s most celebrated power amp for today’s systems—blending raw performance with elegant simplicity. Balanced XLR and RCA inputs, 2 Ω stability, and flexible bridging make it an ideal match for both stereo and home theater setups.
Praised by audiophiles and reviewers alike:
- “The soundstage just bloomed. Bass is crisp… mids and highs are singing.”
- “Ridiculously high damping… bass is tight and controlled at all volumes.”
- “Delightful and satisfying from the first note… impossible to fault.”
Winner of multiple awards and recommendations, including:
