Quote: Ok, I will be careful with my terms. Whatever the nature of the change, the E07k sounds better now. Can solid state electronics like the E07k undergo a break-in period?   The only other reason I think it could sound different to me now is I'm listening in the morning. My hearing...

Quote:   This is good information every potential buyer should keep in mind!    I have an older copy of Audio Purist System Enhancer. I burned in the E07k with this for about 25 hours.   With high res audio, there is now a noticeable, but subtle improvement with the E07k vs the...

Just got one of these units. I'm waiting for an iphone cable to arrive, but meantime am listening to HQ audio over youtube and some free downloaded tracks from HD Tracks. The problem is, I don't hear any real difference on my iMac using Gradio SR80i. I'm comparing the Fiio over USB from the iMac...

Trying to get a sense of what kind of sound improvements I might achieve over my iPhone or iMac by getting a separate DA converter and/or amp. I tried the following test and wondered if it is a good way of establishing comparable sonic improvement you can get with a DA/Amp, or if I'm expecting...

I really liked the e07k review!   However, the story gets more complicated when you start reading reviews on Amazon for some Fiio products like the E17. A number of people do not hear a difference between their PC internal sound card and the Fiio DAC products with headphones like the Grado...

Aw heck, sorry to sound wishy washy but just not sure about this stuff... Presently I only listen to mp3 files, or maybe a CD. Could be played on my iMac or iPhone. Tonight I'm learning about the existence of "high res" audio for the first time. Mostly I listen to pop rock and some pop...

Maybe it would be best to start with the E07k since I'm not sure yet how I will end up using it, and it is more versatile

It looks like the e07k is better if you want to listen to high resolution audio, but if you only listen to CDs or mp3 (my situation), then the e12 would be the better choice. Do I have this correct?

Thanks for the reply! Does the E12 only work with certain devices?

Hey, I'm considering a Fiio product for Grado SR80i running through either an iMac or iPhone (about 50/50) usage. Would you recommend the E12 or the E07k for my situation?

Just got some SR80i (32 ohms) and connect them to an iPhone or an iMac (maybe 50/50 usage). I'm tempted to get a headphone amp and it looks like Fiio is a good brand in the under $200 cateogory.   Based on these considerations, would you recommend a particular amp?    At present, I've...
