New box suggestions

[audio_64]

Hello, I never used Starsat receivers and I need suggestions to purchase my first one because
I don't understand which is the best box for me.
These are specifications I'm looking for:
1) Good audio and video quality, 4K would be better but HD is good too.
2) Multistream support
3) Abertis decoding (Spain, 30W)
4) Stable Forever support (very important)
5) Possibly T2-MI decoding (just an option, not mandatory)
6) Good support and regular firmware updates
Could you please suggest the best choice?
Thank you.

Sr-200 UHD 4K
Sr-90000HD
Sr-X1 Pro 4K (If you are a fan of Android)

Hi,
These receivers all support the specifications you requested.
The difference between them is the type of server and its duration as well as the dongle. (price and quality.... CPU, System...).
As for support, Starsat is known for its good support for new receivers, and support can last up to 04 years.
This is my own opinion, Maybe you should wait for other users' opinions.

Thank you dreams@t for your useful reply.
I do not like android, so it seems that my choice would be restricted between SR200 UHD 4K and SR-90000HD.
Could you please tell me in details main differences between these two boxes based on my request in my first post?
I saw many crappy and very low quality receivers (particularly regarding audio and video quality), so I hope these new boxes could be better than in the past.
Thank you again.
