Used Aurender N100H. They are $900-1200. The Listening Room typically have several for sale, and one can buy confidently from them.

Sonore opticalrendu. I've had this for a number of years. Sounds great.

Innuos was on my shortlist when I was in the market for a streamer without a DAC, However, in the end I purchased an Esoteric with a DAC. Unless your DAC is something really special, I’d suggest purchasing one with a DAC, that is also special.
