I heard the Magico M9 system at Rhapsody DFW. It is the most impressive audio facility I have been to, in a totally bland industrial park building. Chris is an excellent host and I encourage anyone to visit. The room is a room-within-a-room, with thick, designed for audio, walls, floors and 12 foot ceiling. Even the doors are big, thick, heavy and designed for sound. The Magico M9s were driven by a pair of Pilium stereo amps, Pilium preamp, Pilium DAC and Taiko Extreme streamer. The room was built for the system and then treated extensively. So I would think this was as good as the Magico M9s can sound. They sound great as expected, easily the best Magico I have heard
I listened to music that I know well, Rattle/Berlin Beethoven symphonies 5 and 9; Fox/Encores pipe organ, Tchaikovsky Piano concerto no. 1, Mussorgsky Picture at an Exhibition piano, Marshall Tucker Band, Mellencamp, Joan Baez, Chuck Mangione, Coleman Hawkins, Louis Armstrong, and other music. I listened to many of these tracks before I went to Dallas and when I got home. This was only a couple of hours listening but, overall, I prefer the sound from my YG XVi/Boulder 1110 and 3060/Playback Designs MPT8/MPD8/Baetis Reference/2xREL 32 system. On all music, but particularly classical music, the YG system sounds clearer to me, more real. The bass from the M9s compared to the XVi, was at times a bit boomy. On some of the rock tracks, the Magico M9s were equal, perhaps a bit better. So to answer Lee's question, on sound alone, the M9s did not IMO achieve a higher level than the YG Sonja XVi. I am not a reviewer, this is just my impression.
The only disappointment was the Taiko streamer stopped half-way through some tracks including the choral movement of the Beethoven 9th.
