D.A. Hybrid Amplifier Circuit Corrects Errors and Ensures Optimal Signal Reproduction: Sony TA-ZH1ES Headphone Amplifier Decodes Up to 22.4MHz and 32-Bit/768kHz PCM
The reference-grade TA-ZH1ES headphone amplifier touts Sony's exclusive and new D.A. Hybrid Amplifier Circuit, an analog feed-forward amp that corrects conversion errors at the output stage and ensures optimal signal reproduction for your ‘phones. The unit easily decodes up to 32-bit/768kHz PCM and 22.4MHz DSD and offers an array of connectivity. Completed with an over-built chassis to isolate the circuit board from vibration, TA-ZH1ES offers unparalleled sonics at its price point. 100% Music Direct Guaranteed.
"With every set of headphones in my collection, Sony's TA-ZH1ES amplifier generated more bass, smoother highs, and a deeper, darker, more water-like transparency than any I'd previously experienced."
– Herb Reichart, Stereophile
TA-ZH1ES' new DSD Remastering Engine even lets you convert all PCM music sources into DSD 11.2MHz. An FPGA (Field Programmable Gate Array) converts any signal into DSD. TA-ZH1ES also touts a DC Phase Linearizer 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. Further your options and listening experience, Sony's onboard DSEE HX upscaling technology features four additional modes to the standard: female vocal, male vocal, percussion and strings, for optimal sound reproduction.
"There's much to admire in this Sony's sound. It has an impressively crisp and clean presentation, but avoids being thin or sterile."
– What Hi-Fi?
"When I tried out the TA-ZH1ES with the MDR-Z1R 'phones, the first thing that grabbed my attention was the outrageously potent low, low bass."
– Steve Guttenberg, Sound & Vision
D.A. Hybrid Amplification Circuit and Analog Feed-Forward Amplifier
To achieve incredible sound reproduction, Sony's S-Master HX digitally amplifies the music signal without any resulting transmission loss. However, at the final stage of amplification, the physical limits of the semiconductor unavoidably cause distortion. There has to be a trade-off between the high power and high-speed response. Sony developed the D.A. Hybrid Amplifier Circuit to overcome these physical limits. The analog amplifier compares the true signal with the digital amplifier output signal, identifying the error caused by the slow MOSFET switching speed. Then it produces an error-correction signal to restore the headphone output signal, preserving the purity of the original sound, and reproducing the signal with absolute precision.
Over-Built Chassis and Tremendous Connectivity
TA-ZH1ES features a rigid FBW Chassis designed to isolate the circuit board from vibration. The structure of the baseplate supporting the FBW chassis has two layers for enhanced rigidity and a low center of gravity. By minimizing 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 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. TA-ZH1ES features several terminals to support a variety of input devices. A variety of headphone output connections – including both balanced (0.17", 3-pole mini plug x2 and XLR4) and unbalanced (stereo standard plug, stereo mini plug) are also here.
