I have had my R3 now for a couple of days and compared it a little bit with my Caynin N3 and Chord Mojo.
Speed, user interface and the display are a huge step up from the Cayin N3!
The Cayin N3 works as designed, but it's simply cumbersome to use the capacitive buttons.
To make the N3 more or less user friendly I use the HiBy App, but it doesn't support cover art and the BT connection is sometimes hard to establish.
The R3 screen is much brighter with much better colors, and the touch operation is a huge step up.
Mostly it works fine, but scrolling with the A-Z bar is a little tricky and can be slow with a long list (especially cover art loading)
Also the MSEB and equalizer are not always resposive, especially double-tapping the MSEB sliders to reset them often doesn't work.
Very quick sound impressions:
Soundwise the N3 has a clearer and brighter sigature that sounds a little more detailed at first, but also slightly rough edged.
The R3 sounds fuller, smoother, cleaner and warmer. Both have impactful bass, the R3 even more so than the N3.
When I say clean I mean lack of roughness, but maybe at the price of giving up some detail. I feel the R3 has a little better basic DAC abilitiy compared to the N3, and simply presents it in a different way, but still veiled compared to the Mojo.
Compared to the Mojo, the R3 with it's smooth signature is closer, but Mojo is of course much more open, free, spacious. It feels as if the veil is lifted, a weight is taken off the chest and the music is released to flow freely. (pardon that non-objective description, but it's simply what I feel) Mojo has a lighter bass though, I suppose closer to the "original" sound as recorded/mastered.
Mojo has a clarity which comes from very clean sound without any roughness or artificial sharpness. Edges are more defined, but always smooth. It just sounds more natural and analog.
One interesting impression was that with High-Res recordings the R3 sounded closer to Mojo, while with standard 44/16 FLAC the difference was bigger.
I also tried MESB on the R3 but didn't like it, as it sounded quite artificial to me. It's an interesting gimmick but for me the standard settings sounded better.
Value:
Putting the R3 in perspective to the N3 and Mojo I think it is a good value at MSRP and a great value at Kickstarter price.
The Cayin N3 is also a good value at street prices (130€) and Mojo is a great value as well at €400, but a different price and quality class altogether.
PLEASE TAKE THIS WITH MORE THAN A GRAIN OF SALT, IT'S MY INITIAL IMPRESSIONS AND I AM NOT A SEASONED HEADPHONE AUDIOPHILE
