This is an old topic, but, I am wondering about something.
I have a spare original Muses 02. I see I can buy a Z2 on AE for 50 euro, there seem to be few left. (if it is real, don't know if it is a reputable shop)
I like my Z1 with Burson V5i very much. Is has a very up front and intimate sound. So I am wondering what a Z2 with Muses 02 or the Burson V5i will sound. I can also rotate other opamps between devices, I could plug in a Burson V6 Vivid, or real Muses 8920 (= Muses 01 character).
I know the difference between stock Z1 and Z2 is Z1 has more mids, Z2 has a V shaped sound. Z2 has a bit wider sound stage, could be a bit more harsh in the high frequency.
What could happen is that Z1 and Z2 with higher end opamps sound the same in the end.
Any thoughts about it? What is holding me back is that the 50 euro becomes more with 21% tax and custom cost. I also own 2 DSDs and a Z3 so I am complete already. So a Z2 is pure luxury.
