About the Sony TA-ZH1ES

A winning combination

The powerhouse Sony TA-ZHIES headphone amp features a plethora of connection options, so it can work with all types of audio gear. Yet it was tailor-made for the Sony MDR-Z1R Signature Series headphones, and pushes them to their peak performance. Former Crutchfield scribe Dave Bar — a legendary audiophile 'round these parts, and hard man to please — was blown away by Sony's flagship headphone and amp combo:

A winning combination

The powerhouse Sony TA-ZHIES headphone amp features a plethora of connection options, so it can work with all types of audio gear. Yet it was tailor-made for the Sony MDR-Z1R Signature Series headphones, and pushes them to their peak performance. Former Crutchfield scribe Dave Bar — a legendary audiophile 'round these parts, and hard man to please — was blown away by Sony's flagship headphone and amp combo:

"Listening to a high-res version of Bob Marley's hauntingly beautiful Redemption Song through the MDR-Z1R headphones and Sony's TA-ZH1ES headphone amp gave me chills. You could positively feel the anguish in Bob's voice as it carried over the spare, woody resonance of his acoustic guitar. I've never heard this track reproduced with such depth and emotion. Simply stunning. One of the best and most revealing headphone listening experiences I have ever had.

"One of the things I like most about these cans is their ability to unravel even the densest recordings, laying bare each element and placing it into its own respective space. They sound deep, detailed, and transparent without ever becoming harsh or overly analytical — much like the best vacuum tube electronics.

"I'm usually an “open back” headphone kind of guy — preferring their generally more airy and spacious presentation — but the closed-back MDR-Z1R not only provided much of that spaciousness I love, they also delivered the extra visceral punch and power that sealed cans do so well. It's like having the best of both worlds."

Product Research



S-Master Amplifier w/ D.A. Hybrid Amplifier Circuit: High impedance headphones require high power, but this can create a difference between the actual and ideal signal. Sony's non-feedback S-Master technology maintains the purity of digital sound, while Sony's new D.A. Hybrid Amplifier Circuit corrects the conversion error caused by switching amplification for a cleaner, more natural sound,

DC Phase Linearizer: Sony's 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 amplifiers to deliver a more analog-like sound.

Advanced FPGA Processing: To maximize the potential of the new D.A. Hybrid Amplifier Circuit, Sony engineers developed the amplifier using an advanced FPGA (Field Programmable Gate Array) processor.

Structural Integrity: The Sony TA-ZH1ES headphone amplifier has been precision-crafted from the outside in to maximize audio quality.

  • 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.
  • 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, and when used in combination, they suppress each other. The result is the effective elimination of unnecessary resonance.
  • Double Layer Bottom Plate: 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 center of gravity. This added protection and durability enhances sound quality.

PCM & DSD Audio Formats: The Sony TA-ZH1ES headphone amp supports up to PCM 32-bit/768kHz and DSD 22.4 MHz.

DSEE HX Upscaling Technology: Sony's new DSEE HX upscaling technology lets you experience your compressed digital music as the artist intended, in near high-resolution audio quality. You can choose between five DSEE HX modes - Standard, Female Vocal, Male Vocal, Percussion, and Strings - for optimal sound reproduction.

DSD Remastering Engine: A new DSD Remastering Engine lets you convert all your PCM music sources into DSD 11.2 MHz. The technology uses FPGA (Field Programmable Gate Array) to convert any PCM signal into the DSD sound format.


Analog Input: The Sony TA-ZH1ES features a set of stereo RCA inputs for connecting an external analog audio device to the headphone amplifier

Digital Inputs: The TA-ZH1ES headphone amp is also equipped with an optical (toslink) digital input and coaxial (RCA) digital input for connection of an external digital audio source device, such as a CD player.

  • Coaxial (RCA): The coaxial digital input supports 2ch PCM (32/44.1/48/88.2/96/176.4/192 kHz; 16/24-bit).
  • Optical (Toslink): The optical digital input supports 2ch PCM (32/44.1/48/88.2/96 kHz; 16/24-bit).
Note: The digital inputs do not support Dolby Digital, DTS, or other multichannel audio formats.

USB-B Input: The USB-B ports lets you connect your Windows PC (Vista/7/8/8.1/10) or Mac (OS X) computer to the headphone amplifier for playback of 2ch PCM & DSD music files stored on your computer or laptop. If you have a Windows PC, you will be prompted to download a USB driver (Mac does not require this driver installation).

  • 2Ch PCM: 44.1/48/88.2/96/176.4/192/352.8/384/705.6/768 kHz; 16/24/32-bit
  • 2Ch DSD Native: 2.8/5.6/11.2/22.4 MHz; 1-bit
  • 2Ch DSD DoP: 2.8/5.6/11.2 MHz; 1-bit

WALKMAN Port: The side-panel proprietary "WALKMAN" port supports connection of a Sony WALKMAN digital audio player or Sony Xperia smartphone. You can playback DSD Native (up to 11.2 MHz), DSD DoP (up to 5.6 MHz), and PCM (up to 384kHz/32-bit) music files stored on your compatible Sony device. This port will also charge your WALKMAN device (not your Xperia smartphone).

Headphone Outputs: The Sony TA-ZH1ES uses a variety of headphone output connections, including both balanced (0.17", 3-pole mini plug x2 & XLR4) and unbalanced (stereo standard plug, stereo mini plug). It supports headphones from 12 to 600 ohms.

  • Balanced: 1,200 mW + 1,200 mW (32 ohms 1 kHz 1%) 
    • 0.17" (4.4mm) single balanced headphone jack
    • two 3-pole mini headphone balanced headphone jacks
    • XLR4 balanced 4-pin headphone jack
  • Unbalanced: 300 mW + 300 mW (32 ohms 1 kHz 1%)
    • 1/8" (3.5mm) unbalanced headphone jack
    • 1/4" (6.3mm) unbalanced headphone jack

Stereo Pre-Out: The Sony TA-ZH1ES is outfitted with a set of stereo RCA pre-outs to connect the headphone amp to an integrated amplifier or powered speakers. The stereo pre-out can be set to variable or fixed.

Detachable AC Power Cord: The Sony TA-ZH1ES headphone amplifier comes with a detachable 6' AC power cord which will need to be plugged into an AC wall outlet, surge protector, or power line conditioner.


Sony's Hi-Res Audio Player: Sony's Hi-Res Audio Player (for Windows or Mac) is a player software that allows you to play back high-quality audio files stored on your computer through the TA-ZH1ES. You can play back high-resolution audio files, such as PCM (44.1-768kHz; 16-32 bit) & DSD (2.8/5.6/11.2/22.4MHz; 1-bit) files, purchased in music distribution websites, simply by connecting the headphone amp to your computer via USB. You'll be able to create, save, and edit playlists, and play your favorite music in any order.

Top- & Front-Panel Controls: On the front-panel of the Sony TA-ZH1ES is a rotary volume knob. On the top-panel of the headphone amp you'll find push-button controls for Power, Input, Output, Menu, & Gain.
