I am normally using the Silverstone EB01-E with my Rega Ear amp.
The Rega is kind of overpowered for my lower-ohm cans and therefore I needed something a bit less powerful.
I now have just ordered an Aune X1 MK2 Mini, simply because I found a rather good offer for it. Should work well with my Philips Fidelio X2 for example.
I have bought it primarily for the amp, but as it also features a DAC, I wondered how good the bzuilt in DAC of it would be in comparison to my Silverstone EB01-E? Would the Silverstone even be worth to still keep at this point?
