Dayens Ecstasy IVse Power - Stereo Times (USA) review
  • The Dayens clearly had more tonal density; more sonic meat on the bone. Through it, Freire’s artfully recorded piano was slightly more corporeal and the dynamic swings were more apparent. Additionally, I experienced an effect which I hadn’t since I heard the lovely Wells Majestic integrated; namely, electrical silence.
  • String tone glows and you can really perceive at times the felted piano hammer on string effect just prior to the resultant singing tone. The stage is broad and most importantly, Uchida through the Dayens makes you smile. There is nothing missing. You don’t wish for more this or less that. Moreover, the recording sounds suitably less reproduced and more actual. David Abramson, Stereo Times

  • Turning on the Dayens amplifier has all of the drama of turning on a light switch. It is simply on. There are no relays clicking, no delays, no flashing lights, or other indications that anything is happening.
  • "Simple" describes the Dayens Ecstasy IVse almost perfectly. It has no features; it is black; it is a nicely built box. It is an amplifier simplified to the point where it could not be made simpler without losing its ability to function. And that function is to reproduce music.
  • The Dayens Ecstasy IVse reproduces music with life, dynamics, power, neutrality, and tonal accuracy within a detailed and utterly credible soundstage. It is also, apparently, bulletproof.
  • The Ecstasy IVse has done nothing but sound absolutely terrific with every bit of music that I have listened to while it has been part of my system. I am sure Nikola Tesla would be extremely proud of how his countrymen have used his electrical explorations to create an object capable of providing so much delight and beauty.
