The HDACC by Essence™ is the digital nerve center for modern audio systems, actually three products in one; a Digital Pre-amp with its own volume control, a 24/192K DAC for use with your legacy analog preamp or receiver, & the best headphone amp on the market. It supports HDMI, USB 2, Optical, & Coaxial inputs + 2 Analog inputs with A To D Conversion for digitizing & up-sampling older analog content to 24/192K Hi Res, including Remote Control, and a crisp OLED Display that shows you the native sample rate of the input source and the 5 selectable up-sample rates from 44.1K to 192K to choose from for the output.
The HDACC up-samples all low res music sources (mp3, wav files, vinyl, tape too!) plus compressed digital sources like CDs, DVDs, CableTV, Internet Radio, Sat Radio, Media Servers, and everything on your portable smartphones, tablets, and media players to Hi Res 24/192K lossless quality. All your music can play louder, cleaner and much richer, raising the sonic pleasure notably.
Selectable Headphone Impedance Matching between 16 and 600 ohms lets you optimize the HDACC’s fantastic sounding Headphone Amp to your specific brand and model headphone. None of the competitors can do that.

The Coaxial & Optical inputs and outputs are for CD, DVD, a Sonos® Connect or any whole-home wireless audio system.Legacy system owners take note; you can bring the digital world into your analog system with the HDACC..
So what exactly do all the various resolutions mean sonically? The lowest resolutions cant be played very loud, their dynamic range is compressed out to save space. This simple chart by Pono Music reveals everything you need to know. The dark orange is Blu-ray, you can play them as loud and clean as the original master recording, with full dynamic range. The HDACC can improve the sound of all the low res sources, adding fullness and detail, but nothing beats the Blu-ray as the gold standard of digital audio sources.
Many Hi Res downloads of classic albums exist now too, store them on your computer for playback anytime. Upsample your CDs or even your vinyl albums to 24/192K to give them new life. The goal of high fidelity is to play back a one to one copy of the original master recording with no loss.
Note: No USB audio driver required for Mac Computers; USB Audio Driver support for Win 7 / 8 computers only; for Win 10 computer support we offer the model HDACC II-4K. We encourage Win 10 adopters to use the HDMI output of their PC, the data rate increases from 500 Mbps (USB) to 10.2 Gbps (HDMI) for hi res sources. The faster the better when it comes to hi def video and hi res audio.
