The IX and X have arrived with me for review. I'm going to be a very busy boy! Initial thoughts after about 30 mins with each through an xDSD and AK70 mk 1:
Retail packaging is beautiful and a great set of accessories. Very premium in feel.
IX - warm, well rounded. Detailed, articulate, good mids, vocals forward - a refinement of a sound signature I am familiar with.
X - air, space, treble detail my god this thing sounds great, special, jaw drop moment.
Sneaky peaky (the X's have the silver cross, IX's black... just noticed the IX also have "IX" in black, the Xs just a silver "X"... d'oh!):
