Yes. It was an interesting match between the MBL preamp and the Bryston monoblocks. I guess it was sheer luck. I heard the MBL preamp in the showroom and was absolutely smitten by it.
So upon bringing it home and inserting it into the system, its synergy with the Esoteric dac, Brystons and The Music was simply stunning.
The MBL preamp sounded way better in my home system than in the all MBL set-up in the showroom.
Fully agree with you that the ambience and the soundstage of The Music are incredible! So too is their musicality!
