i am thinking i really dont need the big screen nor wifi...and the fact that this does not have a real line out...
Just an opinion
This line out question is interesting. Normally I am a fan also. It avoids double amplification on a DAP, allowing me to bypass the inexpensive and poorer quality internal amp with a superior external one.
However, good home DACs usually have a gain stage. So long as this is clean, it increases the dynamic range for further amplification.
Calyx is suggesting that the M's headphone out, which has an electronic volume control, should be set to 100% to create a true line out of 1.25 Vrms. This is the THD that is produced:
Those are distortion numbers that are better than the so-called true line outs of other DAPs. It leads, I believe, to two conclusions. Firstly, the Calyx M may have the best line out yet on a DAP. Secondly, with 70mW+70mW @ 16Ohm output power, for IEMs there may be no reason to use an external amp at all. It is this second part that has me excited.
