E-DAC 24 bit Miniature USB DAC

Epiphany Acoustics » Products » DACS » E-DAC 24 bit Miniature USB DAC

The E-DAC is Epiphany Acoustics’ offering of the ODAC as designed by NwAvGuy in its own stand alone, custom enclosure. As with the EHP-O2, the DAC has been designed to achieve truly remarkable specifications at an extremely attractive price. This, once again, has certainly been achieved.

The E-DAC is a stand alone USB digital-to-analogue converter which comes in a small form factor aluminium enclosure with custom front and rear panels. Input and power is supplied via the USB input on the front of the unit. There are two line level analogue outputs - via the 3.5mm mini jack socket on the front and the stereo RCA sockets on the rear of the unit. The E-DAC will take your computer audio to the next level and when coupled with the EHP-O2 provides an award winning audiophile experience far beyond their price level.

Lead time to build new orders: 2 working days.

This high end DAC is based on the TE7022L UAC1 engine ES9023 24 bit DAC chip. It supports CD quality 16 bit and studio quality 24 bit at sample rates of 44.1kHz, 48kHz and 96kHz. The on-board filtered power supply ensures that noise is practically non-existent. The DAC is not clocked by the USB port/computer, instead using a high quality on board crystal controlled oscillator which further improves overall performance.

AV Forums
“As far as the audio performance was concerned, the E-DAC sounded excellent with a genuine transparency to the sound, which is the sign of a good digital-to-analogue converter.”
“In listening tests the E-DAC performed admirably with a neutral tone and detailed reproduction. The dynamic range was also impressive, with a clean delivery at both extremes and a well-composed midrange”

Hifi Pig
“This is a very transparent little box of tricks and for the asking price (£99) presents very good value for money indeed.”

    I purchased the E-DAC (same as the ODAC) almost a year ago now. I have compared its quality against several DACs including one retailing at £1300 & I have to say this is stunning in its open sound, wider sound stage presentation & overall performance stood out from the crowd. I compared it to a £3000 CD player & that really shocked me the E-DAC proved it’s point & is happily upfront in my system; best buy by a long shot. PC streaming using Naim amps.
    Best recommendation ever.
    Congratulations to the company for such a good budget DAC.

    I’d been looking for a compact sized upgrade from the abysmal PC soundcard – without remortgaging the house – and I can honestly say this little bit of kit dos the job perfectly.

    I don’t want to resort to hi-fi clichés and hyperbole but it is true that the E-DAC has opened up the sound tremendously. Transparent, with astonishing detail and sense of scale. It is also perfectly minimalist and beautifully made.

    I have the E-DAC connected to a Raspberry Pi playing FLAC music files from an attached hard drive using Raspyfi. Sound is great with extremely low noise through an Exposure XXV Amp and Focal Chorus 716 speakers. The RCA connectors weren’t expected but are a real bonus. The little unit punches we’ll above it’s weight. Now contemplating the EHP-02D. Overall a fantastic piece of kit for the price.

    I was interested in this unit so ordered one expecting JUST a decent performance for £100. I was totally wrong, this unit performs well out of it’s price range and competes with much more expensive units. Limiting it to JUST USB interface has really allowed the designer to optimise this design and deliver big time on a modest budget. It has been decades since I have been this impressed with a DAC. Class act. I will try the headphone unit now.

    My E-DAC has arrived and does exactly what I’d hoped, an audibly transparent DAC for my iPad at a great price. Also arrived quicker than i had expected! Nice to have the RCA outputs too as I’m connecting it to my main hi-fi system.

    I am a very satisfied user of the EHP-O2 and the E-DAC, using AKG K550 and the Beyerdynamic DT770 Pro.

    Couldn’t be more satisfied.
