I have a small fiio e6 amp, but I doubt that will be of much help? 

 

Thanks,

I don't know what the other guy is talking about.  Even the AK100 can drive the 400s (35 ohm impedance and 92.5 db sensitivity) and its amp is much less powerful than that of the dx50.  The amp on the DX50 is more powerful than the typical DAP.  So, yes, you can listen to the 400s on the DX50 without an amp.   On the other hand, they will definitely sound better with a decent amp.   The DX50 has a relatively powerful amp, but it wouldn't be as good as most decent external headphone amps.  Of course, it would sound much better with an even better DAP too.

i almost cried.. the improvement from my ipod is so clear..

the soundstage is very spacious, the directional cues are insanely on another level compared to ipod, the separation between instrumen is so clear, its so detailed in reproducing every instrument that the moment i switch focus on some instrument, i reproduce it perfectly: how lifelike it sound, from where it is coming from and how far is it from other instrument.. i love it! definitely a wolfson fanboy now tongue.gif

the sounds warm, quite warm actually.. the bass are very deep and punchy hence giving ny ears the warm impression.. the treble are not slouch though but the sub bass are kicking my bright phone's driver.. how cool is that?!

the only thing i dont like are the vocals... its harsh somehow and my ipod's cirrus produce smoother female vocal frown.gif

 

+1 to melody gardot

Dx50 & he-400: It seems that I need to try it out for myself then. If an amp is necessary, I'll pick one up later? Any cheap/budget suggestions?

The DX50 doesn't drive headphones too well. you'd be better getting a O2 for the HE-400.

I'm using a bh2 and it drives them just fine

Yeah, but what else have you heard. It's not about volume, anything can make them sound loud enough.

Power does not equate to volume, yes you can plug in HE-400 to DX50 directly and it may play loud enough but the sound will be distorted or clipped on many cases.

 

The HO on DX50 sound distorted at high gain/max volume using my Beyer T1 which is much more efficient than HE-400 at 102 dB/mW.

 

As a guide, someone has measured the max power output of DX50 at 1% THD without distortion/clipping.

For HE-400, you would at least want an amp to "properly" drive it to around 115 dB especially if you are listening to classical music, and it will require around 180 mW of power. For pop and rock music and if you are satisfied listening at moderate to low volume (105 - 110 dB) HE-400 needs around 60 mW.  At high gain, you also raise the noise floor on DX50.

 

If you are ok with that level then it's fine, but it will certainly sounds better with a powerful external amp.

Thanks for the detailed explanation. The graphs give clear details of what you're suggesting. 

 

I'll probably consider selling the dx50 & pick up a dx90, or should i buy an portable amp with the $100? any suggestions?

May I know your actual listening experience for the same song when playing with both DX50 & DX90?

 

Between the, which one sounds wider sound stage with more 3D imaging, better separation & layering, smooth & detail treble (high), great mid and extended faster bass?

There is not much powerful amp that can fully drive HE-400 at $100. Take note that upgrading to DX90 will drive it just fine but not much headroom. 

 

I think you are better off looking for a better amp  at around 300USD. You will end up spending around that much if you sell DX50 and upgrade to DX90.

 

Check out these amps

 

iBasso PB2

Headamp Pico Power

Portaphile 627

 

 

Pretty sure they are capable of driving HE-400 with room to spare. PB2 the most versatile and good value here not to mention the most powerful (up to 2.5 Watts). Other than HE-6 it will have no problem driving any headphone out there.

Anyone have an issue where the scrollbar stops half way down the list of all your music?

Does it also stop playing the music? If you go to a any menu and go back to the "while playing screen" does it fix it. I think it just stuck from from waking up the backlight.

 

I see this happening on my DX90, but it doesn't interrupt the music currently playing.

Music doesn't stop, its just while scrolling through the list of music it'll stop at the halfway mark and refuse to go further.  Sometime's it'll jump from 1/2 to 3/4 of the way down.

That sounds like the touch screen.  Clean it.  :normal_smile :
