"[HEA's] 'LET' (Leading Edge™ Transducer) prototype demonstration was a revelation. That's a word widely abused in audiophile circles, but not one I throw about lightly... The LET undressed the recordings to an almost frightening degree, exposing how the mastering engineer had layered all the component parts onto a unified whole. There was a nakedness to the performance that made other audio sound murky by comparison."

"[HEA's woofer technology] does for the low frequencies what the LET does for the upper ones. [HEA]'s onto something huge – perhaps even the turning point of audio in the 21st century."

Barry Willis in Hi-Fi News, November 2007

"[T]he LET's superfast transient response and other design factors have been clinically demonstrated to affect the human limbic system (which regulates emotion) more than conventional speakers, resulting in a more deeply moving experience. In fact, the company's ultimate goal is to approach the emotional impact of live performance, which has heretofore eluded virtually all electronic audio systems... I have every confidence that we'll be seeing – and hearing – much more from this innovative company in the future."

Scott Wilkinson in Electronic Musician, January 2008

"It's a pleasure to listen to this very exclusive audio, where the pin-sharp quality is something that's just not readily available... 'High Emotion' is the right word for it, because it is an emotional experience... The audio is–if one is listening carefully–just as good as being at a live performance... My dreams have been realized."

"If a speaker is to deceive the mind, to convince this wondrous device that a musical truth is occurring, and thereby elicit the associated visceral emotional response we all crave from our favorite works, it must attend carefully to pitch, timbre, timing, and very important, intensity. Although [High Emotion Audio systems] represent state-of-the-art performance in all these musically important areas, it is in the latter that they are without peer."
