There are some big different with E7 and E11:
1, E11 is a pure amp and E7 is USB DAC first! in fact, we found lots of user buy E7 and used as amp only, that is one reason that we develop E11!
2, E11 consume far more power than E7's amp! so it can drive the low impedance IEM more better! and the sound quality will better than E7 if you use E7 only as an amp!
at the other hand, the playtime of E7 is about 100 hours, but E11 is only about 10 hours, so we select a mobile phone battery, and you can carry and backup battery and repalce it when
the battery is empty!
3, The other different is that E11 use potentionmeter, which regard will have better SQ than digital volume control, but it may not as reliable as digital volume control!
4, E7 is powered by higher voltage, it means it will have higher output power and dynamic!
About the price, quality, We will alway try our best to provide high quality, high performance products in low price!
BTW, E11 is not a upgrade or replacement of E7 , because they belong to different kind of products!
For E7, it have dual usage! and most people had prove it's value both in amp and USB DAC, and with E9, it beome a decent desktop USB/DAC!
For E11, it will be a good partner with iPod/iPhone, Walkman, and also our new HD portable DAP in the coming soon!
