Omtaler av Parasound Halo A52+

The Halo A 52+ provided all the power that my speakers could handle, and did so with aplomb. The soundstage was consistent with no blurring of indi­vidual voices or instrumental details. The new Parasound showed its superiority in more graceful smoothness in the upper midrange and treble, and low bass that seemed better integrated with the upper bass. Overall, I really liked Parasound’s Halo A 52+ in every way.

Listening with the Halo A 52+ in my system was a pleasure. Parasound’s new five-channel amp delivers clear, dynamic sound and has plenty of headroom to handle the explosive effects in movie soundtracks. Stereo and multichannel music also sounded great with the A 52+, making it a versatile all-around performer for entry-level and advanced home theaters alike.

The control and immediacy of the A 52+ made another track shine: “Good on the Ground” by the Vijay Iyer Sextet. In this freeform jazz cut, the saxophone and piano struggle for dominance over a driving layer of standup bass and drums. When I listened with the Parasound and MartinLogan combination, all instruments were distinctly conveyed, and the drums in particular had a muscular presentation. The standup bass seemed a bit softened in attack compared with the sound put out by my reference amp on this track, but overall I was impressed by the bass control I heard with most music.

At all volumes, the Parasound A52+ amplifier never gave ground, nor quarter, to the Martin Logan Summits. Electrostatic speakers are notorious power hogs, and the Martin Logan Summits are no exception. They are uniquely talented at exposing any amplifier weaknesses. Impressively, the Parasound A52+ five-channel amplifier didn’t flinch.
