There is a lot more to be gained in a DAC. Until you have a flagship dac of your dreams, you can get by on a $300 streamer.
In other words the differnce between a $1000 and a $10000 dac is huge but the differnce between a $300 and a $5000 streamer is much less.

I understand everyone has their own opinions and perspectives. I have to say that I patently disagree with this take. The quality of the digital source is very crucial to the overall sound quality of a digital front end. Yes, without question the DAC is an important component but it does not over ride the source component either.
A mediocre source will impede a good DAC. The “bits is bits” attitude is trite and superficial. A better quality streamer/music server will clearly make its contribution very apparent. In the OP’s scenario I recommend upgrading the streamer source first. I believe that the current DAC is of higher quality than the current streamer/server in use.
