ZM 1250 - Sound+Image (Australia - July, 2015)
"Let's be bold here and propose something - you can never have too many amplifiers! Even if your principal system is an astonishingly high quality audiophile set-up, what about the rest of the house? Or what about the 11 channels required for a full (or 7.1.4 at least) Dolby Atmos system? ... With stereo music the amp surprised us: the music was delivered with a combined honey-like smoothness and precision of truly high-quality amplifiers... the dynamic lift with the entry of the band into the song was completely unlimited... We ran several of our favourite Atmos-ey scenes from 'The Hunger Games - Catching Fire Part 1', with impressive dynamic impact and precision in the hemispherical imaging provided by this disc…It's hard to think how a power amplifier could be any more versatile than the Parasound ZoneMaster Model 1250. But that's not the end of it, because this isn't merely a workhorse; it's also an audiophile-quality product in its own right."

ZM 650 - CE Pro: Hands On—Parasound ZoneMaster 650 Brings Audiophile Sound to Whole-House Market
"The ZoneMaster Model 650, amplifier provides dealers with a sturdy, hybrid six-channel or three channel stereo amplifier solution that can drive just about any loudspeaker thrown at it... down to 2 ohms. What really struck me was the level of control it had on the bottom end. I found the amp completely natural sounding—very analog like with a nice neutral tonality and big soundstage. The ZoneMaster 650 is one of the few whole-house audio amps that brings audiophile performance to the whole-house audio category."
