Parasound HALO A31 3-Channel
Power You Can Feel Drop the A31 into your system and everything locks in: voices stand center‑stage, low end digs deeper without bloat, and effects surge with head‑turning impact. It’s the missing muscle your movies and music have been asking for. Designed by legendary audio engineer John Curl, it runs high‑bias Class A/AB (the first ~7 watts in pure Class A) with a direct‑coupled signal path for maximum clarity. A 1.5 kVA toroidal transformer and 98,400 µF of filter capacitance supply clean current on demand, while 250 W x3 into 8 Ω (400 W x3 into 4 Ω), balanced XLR and RCA inputs, and THX Ultra2 certification make integration straightforward in serious home theaters. Praised by audiophiles and reviewers alike: “Clear, detailed sound that belies its price…a joy to listen to.” — SoundStage! Access (Reviewers’ Choice) “Impeccable in fit and finish…powerful but refined.” — Secrets of Home Theater & High Fidelity Covered by Parasound's 3-Year Parts & Labor Warranty.
