HPA4 - Class A Recommended Headphone Amplifier - Stereophile 2021
HPA4 - "Class A Recommended" Headphone Amplifier
"With the hard-to-drive HiFiMan Susvara headphones, the HPA4 showed each instrument in dramatic bas-relief. It accomplished this by presenting cleaner, better-articulated bass and manufacturing a sharper midrange focus than I had experienced previously with either my solid state reference, the Pass Labs HPA-1, or the tubed Linear Tube Audio Z10e.”
- Herb Reichert
"The LA4 preamplifier was the widest-bandwidth, widest-dynamic-range, lowest-noise, lowest-distortion preamplifier I had encountered at that time ... to those virtues, the HPA4 adds equally superb balanced and single-ended headphone outputs."
- John Atkinson

"The setup used ... ten Benchmark AHB2 amps, and a Storm Audio ISP Elite 24 MK3 surround processor."
"The system delivered serious punch and clarity."
"During the car chase and gunfight sequence from No Time to Die, the Krix setup managed to convey the intensity and scale of a far larger theater—tight, immersive, and controlled. Proof that with the right engineering and setup, even a small room can deliver big-cinema energy."
