I tested Prime for 3 months.
It was OK.
Sound quality was a little uneven from album to album, but mostly OK.
I found Tidal to be more consistent and was as good or better than Prime most of the time.
Two larger factors included:
1. Tidal connect integrates better with my Node streamer.
2. On Prime, a number of my favorite albums simply did not play on the Node...giving me faint static crackling sound and no music what so ever.
I tried the 3 month trial from Tidal. HiFi for 6 weeks and HiFi plus for the remaining 6 weeks. At the end I subscribed the the HiFi plan...had no use for MQA. I’ve been very happy with the HiFi plan.
