Hi,
If you go to amazon.com, you can buy your Wiim and have 30 days to return it no questions asked.
Once you do that, you need to get ride of Spotify and get Qobuz. They also have a 2 months free period. I guarantee you will hear the difference.
Once you hear it, you can unheard it. You will never go back. You will only go forward, as there is much much better sound as you are willing to invest more in your system/room acoustics.
If your ever get to vinyl, you will find that the same record, pressed in different years sound completely different. It happens with digital as well.
This hobby is for the long run, but my proposed two trials represent a great start, risk free.
Enjoy!!
