Power amplifiers stereo — Parasound HALO A52+

The HALO A52+ is a stereo power amplifier from Parasound, sitting below the HALO A31 and A51 with more modest output power in a considerably more compact chassis. The HALO A52+ brings Parasound's considered engineering to a more accessible expression of the celebrated Halo-series power amplifier engineering.

Key specs that matter

Input sensitivity is 1,000mV, matching the broader Halo series. Input impedance is 94,000 ohms balanced or 47,000 ohms single-ended, also matching. Output power is 180W into 8 ohms, rising to 255W into 4 ohms - more modest than the A31/A51's 250W/400W. Signal-to-noise ratio exceeds 112dB, matching. Damping factor exceeds an extraordinary 1,100, also matching. At 437 x 133 x 149mm and 25kg, the HALO A52+ maintains a considerably more compact chassis than the A31 and A51.

Sound and use context

Expect exceptionally clean, tightly controlled amplification reflecting the extraordinary over-1,100 damping factor, packed into this considerably more compact chassis than the rest of the Halo power amplifier catalogue.

Pairing

The extraordinary over-1,100 damping factor suits demanding loudspeaker loads with excellent bass control.

Alternatives

Parasound's own HALO A31 offers a more substantial alternative within the same broader Halo power amplifier catalogue.
