Now you've seen one, too:
After A/B'ing from the DX50 and my Sony F-807 headphone amp, and my RSA Shadow and Hornet amps with various IEM's and my HD700's, I would also have to disagree. Its not that the built in headphone amps are bad, just a good quality external amp is better.
Until 1.2.6 I was happy with DX50 and no amp. With the arrival of 1.2.7 I had an intense dislike of the sound. I looked in the for sale area of this very oracle and purchased a second hand amp. By using the line out to amp route, I now find the sound to be constant no matter which firmware is installed. My advice to anyone is to try it and see - at this time I would not return to unamped.
^ Please let us know the brand / model name of that adapter, thank you. I am looking to buy a few.
I second that. Neural network malfunction! Happens to me all the time!
^ Thank you!
I found some US buying options at eBay by searching "USB Type A Female to Micro USB Male Host OTG Micro USB Female Y":
It would be even better, if the host OTG plug is angled (I searched but could not find any).
ok. to be honest thus far i share ratinox opinion. amping is a for headset. why would a low impedance v3's (16ohm) need a amp. if you buy a decent "DAP" i assume there is a good DAC in it. but also a decent amp. otherwise i don't really think you can call it a DAP. for me DAP is a all in one. why does anyone want to stack another AMP on top of his DAP? i have read that the C5 does help against hiss. but shouldn't the low gain option on the DX50 help against hiss?
when we are talking about hard to drive headphones ok a amp is needed to fully unleash a headsets potential. But a low impedance IEM i wonder.
OFC i'm kinda newbie never owned a Amp just saying what a read around on the web. rectify and correct me educate me thats what forum is for.
