So I did the update tonight, I managed on the mac but not so on the windows version. It takes a bit of understanding to go through it but it worked. I wish it was easier like with my profoto gear firmware updates tbh. Anyway, what a difference it makes. The sound stage is wider for sure and there is way more separation in the notes and instruments. Then there is also more timber too. In short do the update. At first I didn't really believe it until I went back and played my select songs that I listen to and know well. I also feel like there is more bass in some weird way. But the timber and clarity is freakily much more. Is it worth it? Totally , in a way it feels little estranged to me as its the same DAC. And its such a nice surprise to know that a piece of equipment you own and love is capable of much more. Some people mention that its nice when a company goes out of the way to deliver more rather than just fix bugs. A big thanks to Vinshine.
