I have the Topping D30 DAC for a few weeks now. It has replaced a very inexpensive ELE DAC D01. Both were connected thru the USB from my Raspberry Pi running Kodi. When I switched the ELE for Topping, my immediate reaction was that I like the ELE much better. It is possible that I just got used to the sound but the Topping is a lot darker, highs are somewhat subdued and songs that I know by heart did not sound as I have expected them to do. Right now the Topping has good number of hours of "burn in" time and it has stayed on for days. I haven't switch it back to ELE to compare them again because I am afraid that the $10 DAC will still sound better than the $130 one. What's your opinion about the D30 compared to what you had before?
