I have both DP-X1 and Fiio X5iii and on there own I myself prefer the DP-X1 by a large margin. I bought the X5iii to use as a source for the Mojo only. I like that I can output DSD via Coax to Mojo with. Its a great source and I have Tidal offline for it as well. I do have my DP-X1 strapped to the Oppo HA2-SE which i love the sound as well.Thanks guys, i did consider and tried x5iii and the sound is not as re-fined as iphone+nutron+mojo, and bass are gone. The one dap came close to mojo in the warm vocal at higher price is AK300 and AK Kann. Kann beat AK300 by the shere volumn of really nice bass note, problem is it's in the $1000 range and it's huge close to the iphone+mojo stack... the other DAP i am consider is onkyo dp-x1a but it doesn't sound close to the thick and warm mojo signture, it sounds relatively digital and cooler.
Ive been trying to get away from multiple devices but, the sound is much better this way.
