I just bought this E70 and played for a week, thats make my life much easier then before.
I was used Gustard X16 and need to power on/off and select input each time. Source is using iodata soundgenic, XLR to Luxman int amp with Elac 407.
E70 sounds is very clear and wide, using default PCM DSD filter, its typical ess sounds. The wireless (BT) sounds impress me. I just using iphone playing youtube music and connect to E70, it will automatic turn on and play. Disconnect it from my phone, it will auto turn off. even using soundgenic via USB and playing movie from TV via optical out, one word..."easy!!". For optical out, i have updated the firmware to 1.04 thats thanks for this post !
Pros: 1. its small and light weight
2. Sounds good enough (only my feelings)
3. auto power on/off
4. BT sounds good (much better then many dac with BT)
Cons: 1. looks low end
2. too light, need to use heavy things resolve resonance
3. volume knob no use for me
