Amplifier with DAC, optical inpit

I choose a stereo amplifier with DAC and optical input, I found these makes TEAC, Onkyo, Marantz, Denon, NAD.
I liked it visually TEAC AI-501DA, Onkyo A-9050. Maybe there's better for this price?
What would you recommend with a good sound?
What speakers are you planning to use with the amp?

Large room? High volume levels?

I use different speakers. (Omega MaxHemp, Audio Note AN-K, Rehdeko RK35)
My room is small. I listen quietly.

I don't know if the amps you list are the best match for your speakers. I'm not saying they won't work, but a demo would be mandatory.
