So I am very happy with the DX90 after more time with this DAP, it does do very well for a portable player. I mean granted it will not match up to my Audio Gd NFB28 balanced desktop unit, which is one of the best bangs for the dollar imo for high mid-tier DAC/Amp. It does exceptionally well reproducing music accurately with detail, speed, clarity. Those are not the only things though because a dac and or dap can have all those things and still not be enjoyable, without a good tonality and or timbre, well it has got a great tone and is very energetic.
I will be receiving the iBasso PB2 balanced amp to pair with this DAP today, I also will be getting the adapter for the 4pin xlr that my HE-560 and my ZMF x Vibros use to use the balanced jack for my music. Will definitely give some impressions and let you guys know what I think and hear.
