Now owning a couple of portable dacs
They are in some sense the same as headphones and iem, they all have their own sound and imperfections.
Not all headphones/ iem shine on the same dac, and some headphones shine in particular music in one dac and acebother music on a other dac.
Let's start with the Fiio m5
This little machine can drive most iem's and not to demanding full size cans. They work ok with my X2hr and hd599 but on max the HE4xx is still not really loud.
Sound wise the m5 is nothing to write home about, it's not really layerd and doesn't have a great sound stage. Dynamics are also far from ideal. They sound is not really changed in terms of soundsignature. Little down side is a hiss in silent parts on sensitive iems. But even on the vl-03 I can hear it.
The big plus on the m5 is you can use it in many ways. Can be a piggy tail dac amp, can be used as USB reciever or sender. Got its own little battery and works as flac player (sd card required). The volume rocker is also a great thing speaking for the m5
The meizu HiFi dac (non pro)
This little and I mean little dac is kind of impressive. Sounds a little cleaner than the fiio m5 and has no noticable hiss at all.
They can drive almost all I have got, noted that the HE4xx klcant get to mind blowing volume but it's enough to listen to.
Sound wise this little machine is more detailed and has a little larger sound stage and seperation compaired to the fiio m5. The sound is also even more natural but to boring in my perspective. (9038s is the most natural but because of the large sound stage seperation and imaging way more exciting to listen too.
Little side note on my 1+7 pro the Meizu stotters in UAPP and connected to fiio m5. In Al other cases it's fine.
The Ibassio dc01
This is my absolute favorite, not because it's the best over all but does the things I like right.
The dc01 got dubble the power of the Meizu and m5 and can power all no problem. It does like some juice tho and will drain your battery quicker.
Sound is warm and some what dark, specially combined with the bl-03 or even the Tin T2.
Seperation, soundstage and imaging is really nice and beats meizu and m5 by far. On the dynamic part it's a little Les good but still better than m5 and Meizu. And that bass wow live it so much on the dc01 all music sounds alive with mind knowing oempfff.
The dc01 has verry little hiss but their is some there which presents it self while switching tracks. But it is little and less than on m5. Also the thing can go verry loud and there is no hardware volume controll to prevent this, be careful!!!
The E1da 9038s
This thing is like a V8, zipos power like no other and can go louder than any other you want to blow up your ears or iem's, Yes you can!
Need something to warm your hands while listening to music, you for it 9038s wil do this for you like a really good friend.
Sound wise this is the most potent dac I have listened to. Detail, layering, seperation soundstage depth and with, dynamics all are Superior on the 9038s. Sound has no color and the thing is like a surgeon knife. Very nice for analytical listening.
When you put up the volume for example on a Tin p1 there is a hiss that increases with the volume (hardware volume control?) But for the amount of power it got I think it's not designed for iem's so we will forgive the hiss.
Real downside is no hardware buttons for volume control as this thing can go loud by mistake way to easly. Also in UAPP on my phone the volume control does not work need to fiddle with this.
