One thing to note if your interested in the streamer is to order it with a new M3. I purchased an M3 but without the streamer and then found out it is $1500 to add after the fact.
I liked the M3 sound but didn't love it so ended up buying a used Bricasti M5 streamer and have since sold the M3 but use the M5 with my NOS R2R DAC.
The M5 with SPDIF was a BIG improvement over my previous streamer. Bricasti told me the M3 with integrated streamer sounds better than using the M5 with the M3.
