Warning - not CD quality! Direct Comparison

Practically, it is already on cell phone in the whole house to control the music via the HiFi system. No Question!
So for 25 but you must not have too high claims to take those direct the wind out of the sails.

But Soundwise are significant differences to notice the good old CD.

Starting position 2x B & W tower speaker. D / A converter and a good Kenwood CD player.
Test Album: Dire Straits Money for Nothing Remastered, normal CD:
Volume, clear resolution, super precise bass, goose bumps. Have so far heard nothing better than reference.

Compare with Spotify - Dire Straits Money for Nothing Remastered HQ quality - Sony Vaio ultrabook:
Much quieter, less clearly audible volume increase despite the volume. Bass imprecise, it all seems very hazy.
!!! No goose bumps)

Conclusion: In order to listen to good music in absolute fullest quality, so it takes more than a PC and a Bluetooth adapter.
The sound is not bad, do not get me wrong, but in direct comparison a wireless adapter has no chance against a CD player. Is seems like a small gimmick and (almost) perfect for transferring new albums or the sound wirelessly from your computer.
Purchase can be made equitable! If the unit does not return.
