I could never afford an expensive DAC such as that but applaud people that can and have the hearing to tell a difference.
I did buy a couple of cheap ones just for the heck of it to decide if I could even tell a difference. The 1st one yes, and actually like it. The 2nd no.
Reminds me of years ago when I could actually afford my first really nice system. Bought all the stuff, put it together and thought WTH? My garage system that cost a fraction of it sounded almost as good. Live and learn in this hobby.
