Humanising digital sound
Our revolutionary design brings our digital amplifiers closer to the analog.
Experience a more natural and full-bodied sound with all the power and dynamics of the digital.
The best of Class A and Class D together
Our new technology makes us the pioneers of hybrid amplifiers on the audio market.
atm-audio amps are most certainly not your typical digital amplifiers
The Gregal-700’s have a more voluptuous soundstage with an involving wrap-around effect. The Spanish duo sounds so good in fact, that I feel they operate at the level of an outstanding Class A/B amplifier while their relaxed bass and midrange sweetness makes one almost suspect listening to a Class-A.

Carefully Hand Crafted
Our amps are based on power modules with Hypex NCORE and EIGENTAKT Purifi technology.
Built entirely by hand using only the best component brands on the market: Furutech connectors, Sonic Imagery Labs op amps, Sparkoslabs voltage regulators and Genalex Gold Lion 12AU7 valves.
Revolutionary Technology
Class D’ typical sound is often too cold, too digital.
We have sorted this problem by adding a tube (valve) that humanises the sound and turns it warmer, more natural, more real.
Enjoy all the power and dynamics of the digital without compromising on Class A’ musicality.
Sophisticated Sound in a Minimalistic Design
Our amps are encased in a beautifully shaped anti-vibration chassis made from a solid block of aluminium with individually milled compartments to avoid any interference.
Each and every product is tested to ensure the highest sound quality.
atm-audio digital amps complemented by tubes is a great idea
While the digital amp provides great detail due to its power, the tubes smooth out the rough edges and round out the sound, softening it noticeably. Amps are powerful, refined and sound more natural.

i-LLEBEIG
Hybrid Stereo integrated power amplifier
The i-LLEBEIG hybrid integrated amplifier consists of a preamplifier with a 12AU7 triode valve and the power section consists of a class D module providing 400W per channel. The i-LLEBEIG has been handcrafted and housed in a CNC-machined, aluminum monoblock chassis, designed to eliminate all forms of interference and provide mechanical robustness.
We have managed to reduce the noise to the minimum level so you can get maximum pleasure when listening to your favourite music.
Its design has been studied to be as minimalist as possible, with just one power switch, an input selector and one volume control with remote
