I'm E5 owner here. nice to meet you all guys.
here is my E5,

Finally, I can found some difference after I put Apple Lossless songs into my iPod. I don't know how to describe. When I plug with my 3.5mm line out cable, the E5 makes all the sound mix togather. But after I change to LOD cable, the sound become better when I play the lossless audio. However, the lossless audio are even worse than mp3 audio if I plug my E5 with a regular 3.5mm line out cable. Thats mean, the LOD cable did some improvement on lossless audio but not so much on mp3 audio.

Now even I can listen the higher sound quality music with my ipod. its ok, i will keep the lod cable at this length because the cable is order from UK. I can clip the E5 on my clothes.

I have got my iBasso D2+ Boa today. However, that amp is too big and its only does improve on the fidelity but I can't listen much on bass. Most of my songs are delivering too much of fidelity and make me so tired to listen on it. Besides, my iPod was also set an EQ at Electronic.

I'm still prefer to my E5 because I am usually listening to korean dance-pop songs which are more depending on the bass side. Besides, my E5 is good enough for listening dance music. Since I does not need much on high frequency but I need much on low frequency.

E5 will improve a bit for your bass i think. However, maybe you can try to burn-in the amp for 300hrs. See whether there have improvement for the sound quality.

tq for your comments, I was switch to another EQ -> Hip-hop. Now the sound for my D2+ is getting better than E5 after I burn-in for more than 100hrs. I will still continue to burn-in my D2+ to get a better SQ.

However, the first day when I get my D2+, my first impression is really disappointed during that moments because its delivering a weak bass and too much of high frequencies. Now it is getting better than my E5 already. The bass already came back to its position and it is getting more elastic with not too boomy. The high frequencies are getting more details. The mid frequency which is the vocal really deliver a very good sound. The overall low-mid-high is quite balance.

i'm same like you a noob before. I am also dunno what mean by "burn-in" before.
