HiFi Voice (Czech Republic) October 2015
"This combination of audio performance without the use of tone controls or filters is dynamic, precise and detailed. Control is evident across the audio spectrum even at high volume where there is sufficient power in reserve. Futhermore, there is no loss of resolution, even with quieter music and low level listening. Parasound manages to reproduce the essence of the vast majority of commercial recordings and various genres on CD or the stereo audio tracks on DVD or BluRay that would satisfy even the most demanding listener. I think the audience appreciated the especially strong, dynamic sound with superb control of bass at all volume levels and an imperceptible loss of the finest details on several audiophile SACDs."
