I believe that you can get partially unfolded 24/96 MQA from the digital outputs. We have a few different analogue amps. Maybe we should have an chat offline? I am about to start preparing Sunday lunch for a dozen people, so I will be up to my eyeballs in cheese sauce and gravy for the next few hours. Happy to have a chat tonight or in the week.
Per my response above, you do get partial MQA via digital (depends on file, but mostly 48/96).
If you want full fat MQA you will have to either buy a product that produces this at the analogue out (eg Bluesound), or buy a DAC that is MQA enabled. Not too many of these around; at the budget end the Meridian Explorer 2 USB and the Mytek Brooklyn at the costly end. Doubtless others will emerge.
If you really want to try out MQA, but end up using partial via the digital out of a Bluesound, then you'll always have that little niggle.
If you've got the budget, I'd buy an Aries and output the digital to a Brooklyn. Both of these items are easy to sell on and retain value well (you could even trial them from a dealer, if you've a serious intent to buy if they float your boat). At least that way you'll know that you gave it a very serious try. I might buy a Brooklyn myself but I'll probably splash the cash on another serious CD player instead!
Don't overlook the app. the App can make or break a system, IMO. The Bluesound is pretty good, but as I noted above you can't sort Tidal Favourites. The Lightning App is generally easier to use, with more functionality. It's also easy to identify Masters files in the Aries App. Plus you get more information on the details of the file actually playing.
