SONY TA-ZH1ES, manufactured in 2020 Sony Headphone Amplifier High-Resolution, DSD, Balanced Connection Compatible Includes: Main unit, power cable, remote control, and instruction manual. Functionality has been confirmed with WALKMAN and iPhone connections for music playback and remote control operation. Primarily used with the input side WALKMAN terminal and 4.4mm balanced output connection, but I'm selling it as I don't use it much anymore. It delivers a rich sound and expansive soundstage with high output, unique to stationary models, that even the NW-WM1ZM2 can't match. Quoted from the official website: Equipped with a proprietary "D.A. Hybrid Amplifier," this headphone amplifier with a built-in DAC supports high-resolution audio sources such as DSD 22.4MHz and PCM 768kHz/32bit. It features proprietary technology "DSD Remastering Engine" which converts all PCM audio sources to 11.2MHz equivalent DSD signals, and upscaling technology "DSEE HX." Equipped with five types of headphone terminals, allowing direct connection of major balanced-connection headphones without the need for conversion plugs. 【High-Quality Sound Playback】 SONY's headphone amplifier supports both balanced and unbalanced connections, providing clear and high-quality music playback. 【Multi-Function Operation】 Intuitive button layout and digital display allow for easy operation. A remote control is also included, providing a comfortable music experience. 【Robust Design】 Made with durable materials and designed to withstand long-term use. The simple and stylish appearance is attractive. #SONY #Sony #HeadphoneAmplifier #Amplifier #Earphones #HighResolution #BalancedConnection #IER #MDR #Z1R #TA-ZH1ES #PHA #Walkman #WALKMAN #NW #ZX
