As a musician with some recording and mixing experience it’s important to me to retain as much intentionality in any given production.
Given that I can very highly recommend this Bryston BP-6 preamp. I used it for many years with excellent results with my McCormack DNA 0.5 (Rev A) amp and the sound was very transparent and open yet never harsh with a clear and expansive 3D soundstage. Here’s a nice used piece at a good price (with remote) for sale now…
For the DAC I currently own this Musician Pegasus that would likewise work well because it’s very neutral yet as an R2R DAC is also quite musical. Here’s one used (not mine BTW) at a good price…

If you go this route you could add something like a Denafrips Iris DDC down the road that improves both the clock and allows for a superior i2S connection with the Pegasus that provides a significant performance improvement for not much $$$ if you buy used — that’s what I did.
For the streamer and if you’re trying for a lower budget I’d get a Bluesound Node (model 130 or later so you get the USB output) as it’s a good streamer for the money and has good software, and you can add a better external linear power supply again for another significant performance boost that’ll rival much more expensive streamers for relatively little $$$. If you bought all this you’d be in excellent shape for around $3000 although you’ll still need some good cables. Just one idea FWIW, and best of luck.
