It’s a sin !

I know it would be called a “sin “ BUT, is it possible to feed say a Spotify signal into a “ ? “ and from that, put leads into my Crown preamp?.........m
I'm a very happy Spotify user. I stream Spotify from a laptop or phone, via an Auris BluMe HD bluetooth receiver, into my Rega Elicit-R integrated amp. It works great, and the sound quality is perfectly acceptable to me.

The Auris BluMe HD is the best of the 3 bluetooth receivers that I tried. Not only did it have a more stable connection, but the sound quality was also superior.
Pray for forgiveness.
