I first of all would like to thank Oliver at Epiphany Acoustics for selling me the EHP-O2D at a reduced reviewer discount price. I purchased this Amp/DAC combo after wanting a something better than my soundcard (at the time it was a Asus Xonar D1, which has now been replaced with the Xonar DX on my new 2012 built PC) for my headphones. I did quite a lot of research whilst thinking about DAC combos and the EHP-O2D not only caught my eye due to its capabilities, but also due to the fact that it was built based upon NwAvGuy’s specifications.

Initial Impressions Here are my initial impressions of the EHP-O2D:
-Quick switching between low and high gain
-Very simple plug and play into PC
-ODAC works marvellously
-Drives my Denon AH-D2000’s very well
-With no music playing, HDD can be heard on the PC (whilst connected via USB)
-Clear representation of the music – Transparent sounding
-Clean and lean bass response
-Bulky (white) power adapter
-Works on my Samsung Galaxy S 3 GT-I9300 as a USB DAC (needs power though), and thus by-passes the audio 3.5mm jack of the SGS3
Overall the EHP-O2D is extremely impressive. For the very affordable price of sub £200 for both a DAC and AMP, it seems to be the perfect solution for people like me who want a desktop headphone amp, that produces a very clear and transparent reproduction.
I’ve been very much enjoying the amp, and so far it puts my Asus Xonar D1 > Logitech Z-5500 > Denon AH-D2000 to shame. My desktop headphone rig is currently using the EHP-O2D, directly being connected via USB, and being used directly via “output” to my Denon’s. I can finally enjoy music at home, through my PC, for late night listening, or audio analysis/reviewing – whereas beforehand I would have to use my SGS3 for a more “truer” sound.

Here are my impressions of the MJ2 interconnect (2m red):
-Great quality wire
-Good jacks, with no signs of problems throughout the wire (unlike other wires I’ve previously owned)
-Reproduces music very well, and brings out the mids, with no loss of sound
-Flexible enough, but not so much so that I can make it twist a full 180 degrees on it (I suspect this is mainly due to the fact that this wire is long, and has a nice sheeting around it, thus rendering it less flexible – its use is made for the desk, and not on the go, another reason why I bought the 2m version of it)
Overall my initial impressions of the MJ2 cable are extremely positive, especially at the price point it comes at (around £13) – it should be a no brainer for anyone looking for a 3.5mm interconnect.
Here are my impressions of the MJ2 interconnect (7cm black):
-Well made, craftsmanship is very good
-Has a nice reinforced jack
-Great sound quality
I am also impressed of the short 7cm interconnect, mainly because of the sound quality that I get from it!
Hope you enjoyed the unboxing, pictures & the initial impressions!
