💪 Power You Can Feel, Control You’ll Love
The HALO A21+ brings impressive, effortless strength to your system. Whether you're playing a classic album, movie soundtrack, or streaming today’s top hits, this power amp delivers crisp, controlled sound that fills the room without ever sounding harsh or strained.
Built on a legendary John Curl design and refined for real-world listening, the A21+ blends raw performance with elegant simplicity—it’s about feeling the music, not measuring it.
💬 What Listeners Say
- “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.”
🛠️ Where It Fits in Your System
The A21+ is the muscle behind your speakers. It pairs with a preamp or processor—connecting via RCA or XLR—and drives your speakers with ease. Use it as the backbone of your stereo system or power the front channels in a high-performance home theater.
Need more power? The A21+ can be bridged for 1,000 watts into 8 ohms—perfect for a subwoofer or a custom setup.
✨ Why It Stands Out
- 300 watts per channel into 8 ohms (500 watts into 4 ohms)
- High-bias Class A/AB for rich, natural tone
- Legendary John Curl circuit design
- Balanced and unbalanced inputs with gold-plated connections
- Stable down to 2 ohms for demanding speakers
- Elegant design with metal end caps and subtle gold accents
