Well, the good news is that the Andromeda Special Edition: Gold are, to your ears, sufficiently good that you're willing to change your DAP and flip your Solaris
Now, it seems to clearly suck for ZX300 owners planning to use it with the Andromeda SEG on SE (I'm one of them) as it's either cough up the money for a balanced cable and deal with switching cable or an adapter… but, to be fair,
this is hardly Campfire Audio's fault.
As far as I am concerned I'm split — so far in theory, since I'll get them on Monday (but I don't except anything different than what you posted):
1 - The Andromeda SEG seem to be driven so well by (my) other two main sources (iPhone & MacBook) that getting a balanced cable in order to get their full potential on my ZX300 seems like a hassle;
2 - However, for the price of that cable — as long as we're talking about the Smoky Litz Cable in 4.4 which is the one I am planning to get —it is far cheaper than the alternative;
3 - Indeed, I *love* my ZX300, it's UI, feel, look and pretty much everything. I also invested so much in music that I want it to be my main source. $100USD even with shipping and customs is a better investment than the equivalent of 4 months of Tidal Hifi subscription. I want to own my music and do whether I want with it. I prefer liberty to convenience but that's just me.
