I have used both Tidal and Qobuz over the past 6 months streaming through my Aurender N 200. Both work well and no hiccups on Conductor with either streaming service. Based on my music preference - jazz, female vocals, R&B - I am finding Qobuz to offer a wider selection. To be honest I can't tell the difference in sound quality between the two.
Re the pronunciation of Qobuz - its " Kow - buhz " At least thats how I am pronouncing it!
