Parasound HALO A31 3-Channel Power Amp 400W x 3 into 4 Ω Black
🔥 Home Theater Hack: Make Your System Roar
The A31 is the secret weapon for people who want their movies and music to hit harder. Add it to any underpowered AVR and suddenly your front three speakers—left, center, and right—come alive with real-world punch, depth, and clarity. Dialog gains presence, bass tightens up, and action scenes feel like they’re happening in the room.
With 250 watts per channel into 8 Ω (400 W into 4 Ω), this three-channel powerhouse is the easiest way to level up your system—without rebuilding it from scratch.
💬 What Users Say
- “Clear, detailed sound that belies its price.”
- “A joy to listen to—rich but never muddy.”
- “Drives any speaker without complaint.”
🛠️ Where It Fits in Your System
Connect the A31 to your preamp or AV processor—especially the front pre-outs on your receiver—and let it take over the heavy lifting for your main channels. You'll get cleaner output, better dynamics, and more headroom for both movies and music.
Many customers use it as a “booster” amp: front channels run through the A31, while the receiver still powers surrounds. It’s an easy, effective upgrade that brings serious performance with zero fuss.
