Why not just buy the Denefrips streamer which have i2S format. That is if you use a computer.https://www.denafrips.com/ddc
Email Alvin and he will give you good advice. He told me the cheapest IRIS works great with the T+.
I also use the Sonore OpticalRendu with my music server in a different room. I have a PowerLine subnet for some of my streaming needs. This noisy infrastructure including an electronically noisy computer is tamed by the fibre optical wire going into the OpticalRendu.
other streamers won’t do anything better unless they have i2s format, which may (i emphasize may) be preferable as clock and bitstream are transmitted separately
I do not agree with this statement since my head-to-head comparisons with 3 different streamers, Sonore microRendu, RJ45 Network streaming in KRELL K-300i integrated, and Sonore OpticalRendu showed me that the OpticalRendu was miles ahead of the other 2. I tested this out on my floor standers and RAAL SR1a headphones.
