Guess it also depends on if you plan on going balanced and have or about to invested in a good set of balanced cable. I wasn't about to spend a couple hundred bucks on a set of 2.5mm cable that Sony is phasing out and no one else is using and I was looking at new not used. They do sound different but I would suggest that Witcher should try 2A balanced before saying the 3 have a wider soundstage as the 2A have a larger soundstage running balanced than the 3 running SE. The bass on the 3 is heavier but not any lower and if there was more extension in the high, it's happening outside my hearing range (I'm over 50). Also, the mid on the Z5 is already recessed and would feel more so on the 3. I don't want that. The only reason I just invested in the 4.4 Kimber balance is that most have agree that the recessed mid was brought a bit more forward using the Kimber.
I did. Sony brought out all the cables for me to try with it. I did the Z1R and Z7 balanced as well. I agree with the Z5 mids being recessed, but this was nicely solved with their upgrade cables.
