Parasound HALO A52+ 5-Channel
Big‑System Sound, Smaller Footprint Drop the A52+ into your system and the whole room wakes up. Voices lock center‑stage, bass tightens without bloat, and big moments hit with the kind of weight that turns movie night into a grin‑inducing event—no rack overhaul required. Designed by John Curl, the A52+ runs high‑bias Class A/AB in a direct‑coupled topology for effortless clarity. It delivers 180 W x5 into 8 Ω (255 W x5 into 4 Ω) with a custom 1.5 kVA toroidal transformer (independent secondary windings per channel) and 100,000 µF of reserve for clean current on demand. Full power is rated down to 5 Hz, and integration is simple: five XLR + five RCA inputs, plus 12 V trigger or audio‑sense auto‑on for any AVR/processor with pre‑outs. Praised by audiophiles and reviewers alike: “Delivers clear, dynamic sound and has plenty of headroom to handle the explosive effects in movie soundtracks.” — Sound & Vision (Al Griffin). “Overall, I really liked Parasound’s Halo A 52+ in every way.” — Stereophile (Kalman Rubinson).
