"Suffice it to say that, as with every Benchmark product I’ve used or reviewed, everything works smoothly, precisely, flawlessly. I must single out for special mention the volume control. While the whole unit is completely relay controlled, with a total of forty “precision relays switching high-precision metal-film resistors,” each channel has its own gain control with 256 steps in 0.5dB increments. An accelerator facilitates rapid movement up and down the range while preserving the 0.5 steps, while exact channel-to-channel balance is maintained regardless of changes in level (if you’ve altered the balance to favor one channel, the imbalance is preserved through any level changes until you alter it again). The volume control is designed to generate a light “ticking” or “clicking” sound when used, which I liked. For one thing, it sounds cool; for another, the steps are so fine that without it you might not know you’ve made a change. By far, without question this is the best volume control I have ever encountered, capable of finer resolution of level increments than any in my experience (hard to imagine a set of conditions in audio usage where finer gradations would be required)."
"The LA4 has been widely tested with results that tell the same story as those from the AHB2 power amplifier, i.e., the measurements merely confirm the manufacturer’s claims except in those instances where the limits of the test gear are reached before this or that specification can be precisely verified, almost every tester reporting that the unit beats, often handily, any other ever tested in its product category, regardless of price."

"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."

"An extraordinary amplifier."

"Much more apparent low-level detail in already-familiar recordings"

"The final visual and audio results in this room were indeed spectacular."
"Complete and total immersion, with clean, clear sonics that were not fatiguing at all."
