I asked a friend from Switzerland, who goes regularly, to check out the MSB setup. He's a dCS owner, but I've found him to have a great sense for the nuances of audio gear. Unfortunately he doesn't tell us much (having been in 2019, I found it hard to hear anything with all that going on inside the place):
"Yes, but integrated in a system, I can't tell you much about it except throughout the rooms where there were MSB DACs, they appeared to share a recognizable smoothness and treble reproduction that I liked. Interestingly in all the rooms where they used Wadax, the sound suffered from the exact same linear-sounding dynamic compression, so much so that in those rooms where the playback alternated with vinyl, it bordered on the ridiculous. Bottom line, best digital playback throughout multiple rooms were Lampizator Horizon, dCS Apex and MSB, each brand portraying its own specific 'sound'."
