I really wanted to ear the difference from my PC to a real streamer, and I wanted that every euro I spent for a streamer was on the streamer performance (so no DAC attached, no bells and whistles). This IS it. I usually struggle to ear differences between DACs so I was so surprised when I played the first track through the digione sig. The staging, clarity, less fatiguing sound was a huge step forward. I am totally happy.
One CONS: the preinstalled volumio was not original, so not up-gradable, so I had to buy extra hardware to flash the drive again and the extra money spent for the volumio version was a waste. You are better off choosing the roopie version and flash whatever on your own. I bought it with Nirvana, for me the result is already super satisfying, I don't feel the need to go with shanti, but I don't even know what I may be still missing, only that I am fine like this.
