For those of you who are still wondering or suspect whether the R70X is too laidback or soft. Here's perhaps another better way of describing the R70X - it is neither of those two tonalities. The best I term instead for me to describe is this - the R70X is incredibly insightful. In fact, each and every day I hear it and back & forth with my Koss electrostatics have convinced me one thing - throughout all this years I've been listening to (phones other than R70X) - each do carry a certain tonality to the point that I hear a recording of a sound instead of just well - sound. My Etys had one. My HD598 has one. My AD700 has one. And even my previous and very expensive W5000s ,Alessandro MS Pro and even the supposedly empirically "neutral" Koss ESP950 electrostatics has one.
And all these phones, no matter how neutral from anecdotal reviews and subjective impressions - to my ears do colour the sound. Sometimes aggravatingly so in their own way/s.
The R70X is the only phone I had for the first time (and this is considering I also have heard the LCD2 and the high end Denon D7000 in the past) that I no longer think of numbers or qualitative tonalities to describe it. It just is about the music presented to you, at you - at the right perception of distance. I believe therefore it is the coordination aspect of this phone that is truly the bulk of the magic. Which is unlike anything I've heard, also especially given not at this price level.
Are you familiar with that feeling whereby you have to "clench" your ears everytime for having to really focus on analysing the music? Or clenching your ears as you try to hold on / try your best to ignore against anything that is emphasized at you, no matter how small? Well, the R70X easen / lessen this strain by presenting the sound as is. It is incredibly difficult to describe.
Given you have reasonably quality source & amp, ancillaries, cabling, isolations etc - all you get to hear is "volume" of the music itself. The music is the tonality you will get to hear. If that make sense.
