Superior digital amplification

Our non-feedback S-Master technology maintains the purity of dynamic, straight digital sound. Our new D.A. Hybrid Amplifier Circuit takes this one step further, enhancing its precision and sound quality with an analog feed-forward amp. The analog amplifier corrects the errors caused by switching amplification.

Optimal signal correction

S-Master amplifies music signals digitally without signal loss. High impedance headphones require high power but this can create a difference between the actual and ideal signal. The analog amplifier can correct these signal deficiencies for a cleaner, more natural sound.

Preserving the feeling

Capturing every note and nuance with DSEE HX. Experience your music as the artist intended, in near High-Resolution Audio quality. Our new DSEE HX upscaling technology features four additional modes to the standard: female vocal, male vocal, percussions and strings, for optimal sound reproduction.

Convert any source to DSD

Personalizing sound with the new DSD Remastering Engine. Offering double the conversion accuracy of previous models, the new DSD Remastering Engine let you convert all PCM music sources into DSD 11.2 MHz. The technology utilises FPGA (Field Programmable Gate Array) to convert any signal into the DSD sound format.

Advanced FPGA processing for uncompromised music reproduction

To maximize the potential of the new D.A. Hybrid Amplifier Circuit, our engineers developed the amplifier using an advanced FPGA processor. This let them fully customise the technology and develop something truly unique.

Familiar analog‐like sound

Our DC Phase Linearizer works to effectively replicate a wide variety of sonic signatures. It applies digital-signal processing to match the phase characteristics of various types of analog amplifier to deliver a more analog-like sound.

Eliminating resonance with Acoustically Tuned Panel

The headphone amplifier's top panel is made from a combination of steel and aluminum. These materials each have their own resonance frequency, which when used in combination, suppress each other. The result is the effective elimination of unnecessary resonance.

Ideal sound isolation with FBW Chassis 

The TA-ZH1ES features a rigid FBW Chassis, which has been designed to isolate the circuit board from vibration. By minimizing vibration and preventing lateral movement, noise is reduced for a cleaner, purer sound. The newly added wall structure is made from a large aluminum block for high rigidity.

Rigid and durable

The TA-ZH1ES features an innovative chassis design. The structure of the baseplate supporting the 'FBW' chassis has two layers for enhanced rigidity and a low centre of gravity. This added protection and durability enhances sound quality.
