Dayens Ecstasy IVse, the dual-mono power amp you don't expect
We spent two weeks with the Serbian flagship from Dayens: 28 kg, 350 W of transformers and Mundorf SilverGold Oil capacitors. Listening impressions.
We hooked it up to the Tizo Largo and the Grande Mikra in the showroom for two weeks. Quick verdict: against an unexpectedly large amount of power for the price, the Ecstasy IVse keeps the Dayens family character — tonal naturalness, lively microdynamics, never a smudge on transients.
Build: mass makes the difference
Dual-mono Class AB with two separate 400 VA toroidal transformers per channel, four pairs of Japanese bipolar output transistors per channel. The 28 kg are not rhetoric: you hear them in the bass, where cone control turns into a "firm grip" even on difficult speakers.
Which speakers really sing with it
Speakers with impedance below 4 Ω and complex load curves: this is where current reserve pays. We also tried it on the Ars Aures Estasi and got a reference-grade performance — spatial coherence and dynamics with no compression. Available on request, pending Italian price list.
