"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."
