Hola! DCS is a good brand but also very very detailed and can be fatiguing, I used to have one, so it can be a blessing in disguise’s 😂 that it was out of your budget. DAC and streamer or server are a team and you should be aware of that. Also cables play a super important role. But if you want to focus on streamer first there are two very commercial brands that you can buy used here on Audiogon that are pure quality. Aurender and Innuos. It depends of you want to use Roon or not. Aurender is very sweet, N20 is amazing and you can get a used one for 7.5k but does not run roon. Innuos is more warm and they have tons of models but there are a little more sensitive to cables. A good USB is key too and there are tons of brands in the market. I’ll recommend to go to commercial brands since they manage a better value in the market if you don’t like it. I use Final Touch Audio for USB and it’s very good for the price but it’s not as commercial and Shunyata, AudioQuest or Transparent but I found it better for the price.
my 2 cents and good luck
