After 6 weeks
It's finally back!
It's finally back!
Having made the previous comment, I don't think there is a better portable DAP than AK240. Sorry.
Why would you fixate yourself of finding an amp for Roxanne? It sounded good straight out of an iPhone 5. Even better on Hifi DAPs.
It sure is not about power which is what an amp is suppose to provide since Roxanne like any iems are very easy to drive and don't require much power.
I suggest you better look for a better DAP or source than a portable amp.
I wholeheartedly suggest you listen to the 901 then...
Hi, the only reasons for external amp I can think of are the output impedance is too high of the DAP, line-out is being used, or headphones needs more current. I think if you double amp(amping the headphone output), I think you are hearing colored sound from the added distortion of the double amping, and I believe it amplifies the noise. But, I always thought external amps give you more impact to the sound than internal amp, and don't know why.
Ok, the newer DAPs are still too small to have descrete components like the big DACs out there, so I don't know what they are doing to output better quality sound than the mainstream DAPs.
Also, something I've noticed that my portables(smartphone or mainstream DAP), doesn't sound quite as good at my ODAC/O2 combo, and I believe it's the O2 using more descrete components than what you can fit in the newer hifi DAPs? Not sure what it is, but it does sound better to my ears.But, I don't have a hifi DAP, and only tried the AK120 and 240 which both sounded fantastic to UERM.
Only the previous AK models and ipods which I can see needs amping due to high OI, specially for very sensitive low impedance iems (<18 Ohms)
Fiio and iBasso has been producing very low OI DAPs for a while now. I don't think any new DAPs coming out soon would have a high OI.
As for discrete components, sounding better over opamps. I think it's more of a myth if we talk about driving very sensitive low impedance phone/iem. Also O2 uses opamps and not exactly of discrete components.
Don't get me wrong, a fully discrete design has it's merit/advantage over opamps if we are talking about hard to drive load that requires high voltage and current. Orthos from Hifiman would definitely benefit on a fully discrete amp design.
A fully discrete design might work against low impedance, sensitive load because each component in the chain introduces distortion/noise. If you have many components, it adds up and can be easily detected as hiss on low impedance phones
So discrete components picks up more noise than the components inside IC? Hmm. ok.

You ordered and received your unit in 6 weeks? That's fast.
