I got the same deal and gave the other phone to my wife. One thing about the HiFi DAC is that to me, you don't notice much of a difference between it and other phones unless you use high impedence ear phones. The sound may be a BIT clearer but with regular headphones but it isn't worth the hype until you connect something that actives the higher output. I'm now hearing stuff in songs I've never heard before. I stream Tidal HiFi (and now Master) exclusively.
