I have not used a Streamer or been demo'd one in use in own my System, but have used my owned CDT>DAC Source in Systems that have Vinyl, CD and a Streamed Source.
I have come to viewpoint based on my limited experiences of all the above Sources, that the Streamer as a device is excellent, especially for the user interface and the opportunities to be able to experience musical encounters of various types of genre at the touch of button.
In these limited experiences of a Streamer Device being used in a system that I am familiar with.
The Streamer Experiences that are much lesser in number than any other Sources encountered and experienced in use, have resulted in a outcome that I am yet to discover a Streamer Device that impresses sonically in the same way a Vinyl or CD Source can.
I would suggest the OP keeps their CD Collection, there might be a time arrive, where a different CD Source is tried out.
A discovery that is made, could be the sonic offered from the use of a CD Source, has made the bigger impression and is proving to be the one that has the most attraction.
