And the results were that the UR22 (a $130 prosumer audio interface) demonstrated better control and tonality across the board with whatever I threw at it. Detailing was about the same, maybe the Mojo had the edge, but nothing that really stood out. Comparing the Mojo with the E17 I found that while the Mojo had better treble detail there really wasn't much in it otherwise.
Ok - so I'm deaf I hear you cry. Well that might be partly true as I'm pushing slowly towards 50 and suffer from mild intermittent tinnutis, but I'll also add that perhaps I don't look for the same things in music as some of you guys, and this has set me thinking about what I actually do look for in music that's different from an audiophiles perspective.
The first time I plugged in my K702 into the Mojo. I thought, ah, nothing special, no better then my usual setup - no WOW!
In my main speaker system and with other headphones it makes quite a difference, but AKG are notoriously difficult.
I do not have UR22, but ODAC to Lake People amp, makes K702 sound great. It went like this for weeks. I didn't even care trying it again.
....but the Mojo is not that simple.
Yesterday was listening to some really good jazz recording through my K702, it sounded so good, I just had to try the Mojo with it. I stood up, disconnect the Mojo from my speaker system, plug in the K702 in, and BOOM! couldn't believe it! What was sounding quite good already, starts sounding great, to the point I have no idea how can it sound better. It is not even 100% on audio level, it is somewhat deeper, when you listening to music not just with your ears, but with you whole being.
Something Rob called 'our lizard brain' - it needs adjustment to the Mojo. Also, it needs a well recorded music.
A lot of people will attest that the best things in their lives, weren't simple WOW from the start, but accumulated over the years experiences, that's how I perceive a lot of good music. It requires time to appreciate it and the Mojo helps me in this pursuit.
Some people, especially around this forum are chasing WOW, and it usually manifests in their jump to more and more expensive equipment which is not always leads to the best results. Look at the sale forums, they are full of really expensive headphones and dacs.
The Mojo on the other hand is not the most expensive, and is not always a WOW factor. It is really beyond it. That is, of course, IMHO.
