RedJohn, you have X7, envy you! I'm still using the old X3. I remember X7 can be replaced with a Muses02 amp module. This must be awesome.
Guys, I recommend one CD which is called "Nature's Concerto". By listening to this,you know how amazing A3's soundstage is.
I'm curious is there anybody who's following this thread has lots of different MMCX cables. Twin, are you?
Based on RedJohn and FUYU's review, it is kind of a consensus that switching cable is necessary to get everything out of LZ-A3.
Though taste is subjective, SQ is quite objective (or at least inter-subjective). (Haha, a whisky lover here, who believes personal experience is communicable.)
I'll look for another MMCX cable to see if there's any significant difference.
