Too immature and impractical. I have a Google ChromeCast Audio 96 KHz / 24 bit, connected to a splendid Yamaha A-S1100 and Indiana-Line Speakers all with professional wiring, very satisfied but, I was hoping to hear better quality with Allo-Boss 1.2 and Volumio's curiosity but I am very disappointed and disoriented by so much hype. -Amazon Music HD does not exist, (1 star volume) -So Tidal subscription but if active MQA works at 24bit, if deactivated MQA goes to 32bit therefore unreliable (1 star volume) -I try Qobuz but the quality is identical to the ChromeCast Audio therefore useless (1 star volume) -I am looking for a sort of VolumioCast to transfer music directly from the phone with services such as Qobuz, amazon Music etc ... but there isn't. (Volumio 1 star) -The Volumio application is not very intuitive it does not show the real screen of the streeming service in use, such as the suggestion of the songs according to taste. (Volumio 1 star) How many stars do you deserve ?. conclusion: With the expense of Volumio Virtuoso + Raspberry + Allo Boss, it was better if I was aiming for a (cambridge cxn v2) or looking for cheaper but more functional ChromeCast Audio. I will definitely not switch to Volumio Primo would be ridiculous
