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.


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.”
