500GB Hard Drive for music playback
Store a wide variety of Hi-Res music formats on the 500GB hard drive. Storage space is expandable via USB external drives.

Analog FIR Filters
This digital-to-analog converter effectively reduces high-frequency noise in DSD signals. It features independent right and left channels, with four analog FIR (Finite Impulse Response) filters per channel producing a combined one-clock delay. FIR filters are ideal for D/A conversion of DSD signals.

Digital Sound Enhancement Engine (DSEE)
When turned on, the DSEE offers natural sound with a spacious feel by restoring high frequency sound and the tail shape of the waveform that likely disappears during the audio compression process.

Wi-Fi Built-in
Newly designed built-in Wi-Fi increases whole-house coverage and signal strength. HAP-S1 is rigorously tested to ensure its Wi-Fi signal strength. This real world testing is to certify it will work under the most extreme conditions.

HDD Audio Remote for iOS and Android phones and Tablets
A dedicated app to control your listening experience with the HAP-S1. Create playlists, search stored music and full track control.
|
Expandable storage via USB
Connect external hard drives to expand the player’s storage capabilities.
|
Music transfer software
Compatible with both Windows and Mac computers, this simple music transfer software allows you to select your music folder and sync it with the HAP-S1.

Large Power Source Block Capacitor
This acoustically tuned, custom block capacitor features not only improved electrolytic solution and electrode foil magnification, but also superior case form, sleeve material and length. Only Sony utilizes this component, which is optimally tuned with chemical capacitor length and sleeve cut.

Left-right separated, large bandwidth power amp
This 40W X 2 Class AB analog amp utilizes an EBT (emitter balance transistor) with a cutoff frequency of over 300MHz for the final transistor. The amp device features minimal phase variation up to the high range and excellent transient response. Its twin mono format with separate left and right channels eliminates left-right sound interference and ensures clear, high-quality sound reproduction. The resilient high range reproduces sound with rich musicality and a high degree of faithfulness.
|
High-Rigidity chassis structure
Its all-in-one compact size and sturdy 3mm-thick solid aluminum design extends from front panel to top panel.
|
One-point ground structure
Concentrating audio signal control points into a single point eliminates fluctuation of left- and right-channel, and contributes to dynamic sound.
