It04 vs ca andromeda?
LikeLike
The IT04 has better bass definition. The midrange of the IT04 is more forward than the Andromeda while the Andromeda is fuller in the lower mids region. The treble of IT04 is smoother and it is less bright. The soundstage width of the IT04 is greater. Depth on the Andromeda is slightly more closed in.

Wow, thanks so very much for your quick response. Have the IT01, love it, but the vocal is not enough laidback for my taste IMO
Do you know IEM that has the most laidback vocal with the similiar price of IT01, warm, but still retain the great SS?
Or should I just upgrade the cable?
