Superior digital amplification

Our non-feedback S Master HX 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.

Supports a variety of audio formats

Practically every Hi-Res file format has met its match with support up to DSD 22.4 MHz / PCM 32 bit 768 kHz. Whatever the acronym – from PCM to DSD and beyond – the Sony TA-ZH1ES is prepared to play it flawlessly.

A variety of balanced and unbalanced headphone connections

The amp utilizes a variety of headphone output connections, including both balanced (4.4mm, 3.5mm & XLR4) and unbalanced (6.3mm, 3.5mm).

Rigid and durable for superior acoustic design and sound isolation

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. It also 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.

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 11.2MHz. The technology utilizes FPGA (Field Programmable Gate Array) to convert any signal into the DSD sound format.


The amp features several terminals for multiple connectivity options with your current equipment, like analog input and output, plus digital inputs including optical in, coax in and USB-B - or simply room to expand.

Preserving the feeling

Capturing every note and nuance with DSEE HX. Take the concert feeling home and 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.

Optimized performance for a wide variety of headphones

A two –position gain switch offers both high and low impedance headphones the higher or lower amount of power they need to deliver higher audio levels.

The perfect partner to the MDR-Z1R for impeccable sound

The stationary headphone amplifier has been developed in partnership with headphone sound specialists to realize the potential of the MDR-Z1R headphones. Pair them up to discover an immersive listening experience that will take your breath away.
