I'm going through your reviews at the moment - and I'm a bit puzzled with one bit of info. You commented regarding the crowding of the top ports and called it a potential issue. I could be a 'little thick' here - but bear with me:
- If you're using the headphone out - you won't be using a plug in either the line out or coax out sockets (there is no point)
- If you're using the line out (ie to an amp) - you won't be using a plug in either the headphone out or coax out sockets (there is no point)
- If you're using the coax out (ie to another dac) - you won't be using a plug in either the headphone out or line out sockets (there is no point)
If above is true - then there cannot possibly be any issues with overcrowding.
Sorry - not meaning to be overly OCD - but it appeared to me you were trying to find possible faults that didn't really exist .....
I have tested this out with my good buddy's M50 (my COPs on LO, his on headphone out); sound will come out from only the LO. So yes, your observation is correct that the X5 can output sound from only one of these ports at a time. I am not sure about the overcrowding comment since I have not watched the review yet :X
