HiFimeDIY UAE23 USB DAC (ESS Sabre ES9023+Savitech SA9023)

Audiofilski entry level DAC. Baziran na ESS Sabre ES9023 DAC chipu je idealan DAC uređaj za početnu konfiguraciju vašeg audiofilskog media playera. Može naravno poslužiti i kao kvalitetnija nadogradnja audio izlaza za vaš laptop ili PC. U nastavku je specifikacija proizvođača:

The HiFimeDIY ES9023 DAC was developed by DIY (do-it-yourself) enthusiasts with the purpose of making a really good, but cheap DAC that could compete against regular commercial DAC’s costing many times as much. It uses a DAC chip from the highly regarded ESS Technology. The ES9023 chip is their simplest DAC chip which keeps many of the features of their bigger brothers at a minimal cost.

Simple design with focus on the technical side
You pay for the sound, not the enclosure. We use a small lightweight simple case, so that you don’t have to pay extra for a bigger, heavier and more expensive enclosure.

The power supply in a sound device is very important for the sound quality. We use a high end ultra-low noise regulator (LT1763) and extra capacitors to smoothen the often noisy DC power from USB ports.

The DAC can also be used together with the USB Isolator to further improve the power supply quality. The isolator will isolate the power from the PC and give a cleaner 5VDC power to the DAC. We have experienced improved clarity in soundstage and separation using this isolator together with the Hifimediy DAC’s.
Works with:
Mac, Windows and Linux computers, no drivers required
Most newer Android devices (requires OTG adaptor)
Also reported to work with the Synology DS115J audio station
Raspberry Pi
Features
Output from 3.5mm headphone connector
Volume Level is controlled by the normal volume control keys on your computer (no need to use the volume control inside iTunes etc.)
Normal line level output (2Vrms) when connected to amplifiers/preamps. For headphones the level decreases down to 1 Vrms for 32 ohm headphones
Quality gold plated headphone connector
Additional (bonus) features
USB to optical converter. The 3.5mm output is a dual function plug. If you connect a 3.5mm optical cable it will send SPDIF optical signal, up to 96kHz. Can be use to connect your computer to another DAC or device that doesn’t have USB input.
Highlights about Sabre ES9023 DAC chip
The sound go straight out of the DAC chip to your headphones or amplifier. No capacitor (that colors the sound) is required, there is no DC voltage to remove! Normally a cap is required at the DAC output, it ads costs and reduces sound quality.
Jitter Eliminator! The ES9023 utilISed patented HyperstreamTM architecture and Time Domain Jitter Eliminator.
112db DNR
USB chip Savitech SA9023
Accepts 32kHz, 44.1kHz, 48khz, 88kHz and 96kHz sample rates. Many USB DAC’s use the cheaper PCM2704 usb receiver chips that can only accept up to 48kHz/16bit.
Works in USB Adaptive mode, DAC async mode.
or Tenor chip: (older version)
USB chip TenorTE7022L
Accepts 32kHz, 44.1kHz, 48khz 96kHz sample rates. Most USB DAC’s use the cheaper PCM2704 usb receiver chips that can only accept up to 48kHz/16bit.
Works in USB Adaptive, DAC async mode
ASIO driver: ASIO drivers can provide lower latency, and is to optional to use. Asio drivers is only recommended for advanced users, and is not required for normal audio playback.
Savitech asio driver available here.
Tenor Asio driver for TE7022 version can be downloaded here.
