The first time I hold this amp to my hand, I feel the build quality of amp is top notch, dare I say it's better than ALO's amps or many other branded amps in the market right now. The Ortofon feel sturdy and very precision. Perhaps the thickness can become problem for pocket size though.
Ortofon's product always impress me how they can produce beautiful and sweet midrange, from their IEM, desktop amp, and now their newest portable amp. For me the main point of this amp is indeed about the beautiful vocal and midrange. It's not overly forward nor laidback. It has a bit airy sensation (far from muddy) that can bring the dynamic sound become more enjoyable.
What surprise me is about the bass presentation, I never think Ortofon will make the bass punch can become this good (consider their other product usually have weak bass punch), in this amp is definitely not weak, though not as punchy as RX MK3.
What fail to impress me however is the soundstage, no, it's not sounds compress, 2D or too narrow. But when I compare to other good portable amp such Portaphile 627 then I feel the Ortofon just become less spacious and has smaller imaging. The competition is though this day.
After try it with some IEM and portable headphone, I like the synergy the most with ESW11 LTD. Midrange lover who want portable set-up should try this combo!
*If you want to get a very powerful portable amp, you should stay away from this amp. When I paired with Iphone and Beyerdynamic DT770/250, I can reach the max volume easily without exploding my ears. (I'm not type of person who love hearing music very loud)
