if by “streamer” you just mean streamer, then I’d go no more than 10% on streamer. ($7500 on a streamer is a complete waste of $.) If you mean server and streamer, Maybe as much as, but no more than, 20-25%. In the former case, there are also a number of really good all in one streamer/dacs so you do not have to make that decision. For example, the Simaudio DACs are really fine streamers as well. It would be helpful if you gave more info about your use case. How do you stream now? Do you use Roon? What’s your current DAC?
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
