What's a real upgrade from LuminT2


I am looking for opinions of what would be an upgrade from my Lumin T2 streamer/DAC. I almost totally steam everything I listen to these days. So I am curious as what a real world upgrade in sound quality would be from the T2. Either a stand alone unit or perhaps just a different DAC. I am not dissatisfied with the sound, just looking for something better if it's out there.  Using a Modwright integrated with Tyler Acoustics Woodmere II speakers, synergistic research cabling with a Prutain line conditioner. Home made distributed bass array as well.

Wouldn’t the ROON READY LUMIN X1 using a direct Fibre Optical cable from a Network Switch be the the obvious choice. When I used a lesser type of Fibre Opical (Sonore OpticalRendu) i had a massive improvement in all my DACs. Going direct into a LUMIN X1 is something I really need to hear.

The only other DAC that I am aware of that has the same Fibre input as the X1 is the new $40K LINN DAC/Streamer

BTW - I just realized that my comment is based on a computer serving the music (ROON Core) somewhere in the house away from the audio system. The Fibre cable should make this a non-factor.
I replaced an OPPO 105 with the Lumin unit. Mostly to try out Qobuz and to see what the MQA hype was all about. In the end I do think is has overall a little better sound that the OPPO, but I have had it over a year now and was just wondering what would be a good DAC to try for even better play back. I am not didsatisfied with the Lumin in any way. I just have not hear it compared to anything else but the OPPO. And I felt there were likely some better choices to be had, thanks, Allen.
