Not by far Jeff, DAC implementation is mediocre at best, not powerful enough to drive highly sensible IEMs properly. Initially I thought different, I have a Asus Zenbook UX501VW laptop which touts Bang&Olufsen audio and sounds OK - if you have nothing to compare it to. But I do, I also have a Microsoft Surface Pro (the new one) and it sounds better than the Asus. The Galaxy S8 sounds even better than the Surface which made me believe it's a well thought headphone out.
Then I tried the K1 on the S8 and was blown away by the sound. It's not something you need to listen hard to hear, it's apparent from the first seconds of the first track, be it lossless or not.
The K1 is a $40 DAC& which makes it dirt cheap in audio terms, it's an entry level mid-fi DAC at best which goes to tell how bad the audio in a $800 smartphone & much more expensive PCs must be.
I like the idea of wireless audio and will get on that wagon too but first the technology must mature. Right now aptX is a lossy codec like it or not, you're not getting bit perfect playback in the external DAC using it. Good read here

If you want the K1 make sure it can drive your gear, it outputs 75mW @ 16ohm and 35mW @ 32ohm. I'm using it with iBasso IT01 IEMs and the synergy is great, the very well controlled sub-bass is pornographic.
BTW I highly recommend the IT01 to whoever wants a IEM that sounds waaaay above it's price bracket. They sound head and shoulders above my Sennheiser IE80 which costs 3 times more.
