Oppo 205 + Tidal/Roon Via Ethernet Now - Should I add a MQA decoder? - need your wisdom

Here is my current setup which is only used for two channel audio.

(1) Using an ipad to control the Roon App.
(2) The ipad Roon App plays Tidal music and controls the songs and volume on my Oppo 205 via ethernet (they are all on the same network) 
(3) My Oppo 205 is connected to a PS Audio BHK Signature Preamp via Right/Left XLR Cables.
(4) The PS Audio then feeds my 611 amps through Right/Left XLR Cables
(5) My 611 amps feed to my 803D3 speakers.

I have been listening to this setup since i retired for over a year now and I LOVE IT - amazing sound and very easy to use.

All the while I thought I have been listening to MQA quality. It turns out (as most of you know now that i have studied these forums) i need a streamer to "unfold" the MQA because the Oppo 205 does NOT "unfold" MQA through the Ethernet connection, rather the Oppo can only "unfold" the MQA through the USB

So I thought it would be easy to find a streamer that i could control via my Ipad as i do now. My hope was the streamer would "unfold" the MQA music and i would plug this streamer into the Oppo's USB port and I then have MQA capability

It isn't that easy - I can't find a <$1,000 streamer that i can control via an Ipad that will unfold MQA and has a USB out to plug into the Oppo 205 other than a used Mac Mini

I am not a tech guy and I am concerned it is difficult to get a mac mini set up to do this. Also i don't have a screen to plug the mac mini into so I don't think i can set it up/control it

Please let me know if anyone has solved this and if its worth it (i.e. introducing a streamer into my system to get MQA capability and if so, which streamer you recommend)

Thank you
