Great news and great timing. I had been a Qobuz Sublime+ member, but reverted to their £19.99 a month service for a few months at the end of last year. I've had a promo Tidal HiFi subscription sine November, which is ending next month. The new Qobuz Studio sub, of £149.99 for the year, is just too good to miss. There are elements of the TIDAL service I like better, but not for the extra £5+ a month, and, like Cebolla says, there is no messing around with MQA decoders via Qobuz.
So, net result, one years sub to Qobuz Studio purchased, and TIDAL sub cancelled (to stop it renewing and billing me in a few weeks time).
