Streamer/DAC

Hello guys, man do I enjoy my McIntosh system, but looking for a minor/major upgrade in my streamer.  Hopefully, you guys can help me out

I’ve commented in this forum a few times before. Please, any negativity towards my system/Layout can you keep it to yourself 

Thank you very much for that.

I have:

Mcintosh C53, pair of McIntosh 601’s, pair Martin Logan Renaissance 15a’s and a Bluesound node 2

I Don’t really want to invest in a new DAC.  I think the one in my McIntosh C53 is adequate enough  

Question is, if I invest in a new streamer can I expect major improvements in my sound, and if so what would you recommend
