I am using Bryston 28 SST monoblocks driven diectly by the dCS Puccini and U-clock, for The Music. They seem to be a good match. It all depends on your room.
After a couple of months experimenting with toe-in for both the Music module and the base itself, plus the switches at the back, I find the response pretty flat throughout. I don't think you need a sub unless you listen to a lot of organ material.
The nice thing about the Music module is the way you can adjust the sound and soundstage in so many ways to suit your room. Be patient with the set-up. Every few mm make a difference and the micrometer read-outs are a tremendous help. Enjoy!
