I recently initiated the 30-day trial of Studio. I've used Audirvana for years, but less so over the last several months. I was surprised by the subscription business model and to learn that my current software is now a "legacy". As a long-time Tidal subscriber, I have no issues with subscriptions so long as there is performance value for the investment. I am running the Benchmark amp and DAC3L with the LA4 preamp to be added soon. Sole source is my MacBook Pro via USB. The Studio download went fine and, though early days, I am very impressed with Studio over Plus. I hope to have more to say on this down the road. Now, what I don't like is the vague support system which seems to rely on the "community". I preferred sending in a question and Damien, et al, responding. This is the Benchmark Audio support model which, for me, distinguishes real customer support from the community approach that is merely a convenience to the company. I'm also concerned by comments relating to issues of compatibility with the MacBook. I haven't had any problems so far, but they would be a deal-breaker. So at this early stage I am really like using Studio and will gladly pay the subscription rate if no tedious software issues. Good job Audirvana.
