Technical Features

The TA-ZH1ES utilises the non-feedback S-Master technology, amplifying music signals digitally without signal loss, maintaining the purity of dynamic, straight digital sound. High impedance headphones require high power but this can create a difference between the actual and ideal sound. The new D.A. Hybrid Amplifier Circuit can correct these signal deficiencies for a cleaner, more natural sound. Featuring DSEE HX technology, the TA-ZH1ES upscales music to near High-Resolution Audio quality. It has 4 additional modes to the standard: female vocal, male vocal, percussion and strings, for optimal sound reproduction. The DC Phase Linearizer works to effectively replicate the phase character of a typical analog amplifier. It matches the phase characteristics of the analog amplifier to deliver a more analog-like sound.

Offering double the conversion accuracy of previous models, the new DSD Remastering Engine allows conversion of all PCM music sources into DSD 11.2MHz. This technology utilises FGPA (Field Programmable Gate Array) to convert any signal into DSD sound format. To maximise the potential of the new D.A. Hybrid Amplifier Circuit, Sony developed the amplifier using an advanced FGPA processor. This lets them fully customise the technology and develop something truly unique.


The TA-ZH1ES features a rigid FBW Chassis, made from a large aluminium block, which has been designed to isolate the circuit board from vibration. By minimising vibration and preventing lateral movement, noise is reduced for a cleaner, purer sound. The headphone amplifier's top panel is made from a combination of steel and aluminium. These materials each have their own resonance frequency, which when used in combination, suppress each other. The result is an effective elimination of unnecessary resonance. 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.
