@dunkin You ask do I need a dedicated streamer?
I answer, ‘No you do not.’
But I interpret those who have tried to counsel you on this matter, that, considering that you have a good DAC, amp, and speakers, if were to TRY a dedicated streamer (and perhaps some software delivering lossless audio), you would WANT a dedicated streamer. The sound is that much better. But far be it from me to tell you what to do. Be happy. Listen to the music.
