HPA4 Review - Chris, DC Hi-Fi Group
"The Sound of Silence"
"Benchmark Audio is an engineering focused company with a deep heritage in the recording studio world."
"The HPA4 is a Headphone Amplifier and Preamp that incorporates the THX-888(AAA) achromatic audio amplifier circuit that was first introduced to the world in the Benchmark AHB2 amplifier."
"To this day the AHB2 remains the lowest distortion and highest SNR amplifier on the market."
"The Direct Opposite of Typical Tube-Based Technology"
"From a listening stance it is the cleanest and most accurate delivery of sound you are likely to get with any Hi-Fi component."
"This is the direct opposite of the typical sound of tube-based technology that is awash in second harmonic distortion and noise."
Power
"The HPA4 …offers 6 watts into 16 ohm and a whopping 11.5 Vrms into 300 Ohm headphones."
"You will not be running out of power with this device."
Listening
I used the track "Slink" from the brand-new Artemis album on Blue Note."
"It is a very dynamic driving track and the Artemis ensemble makes the most of it. The HPA4 and revealed all the sonic details of this track."
"I give the HPA4 my highest recommendation."
