15k for streamer and dac....how much on each?

for a music first, streaming only, two channel system.......with 15k in pocket (can buy new or used)  is the general rule of thumb 50/50 split on the budget?

do any all in one units at this price point compare to separates?

What choice did you land on at your respective budgets?

I've not had the greatest experience with streamers.....sound more similar than dissimilar to my admittedly non golden untrained ears
