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

I bought a dSC Bartök in early 2022 and was very happy with it. When the opportunity came to upgrade it to the Apex version, I waffled a bit but ultimately had it upgraded. After burn-in, the changes were not insignificant. I wanted to bring in a Mola Mola Tambaqui for comparison, but I’ve decided that I am satisfied for now. Used, the dCS Bartök Apex is within your budget. It does not require a separate streamer. 

You definitely want a dedicated streamer, DAC and external linear power supply. I was surprised how much the sw improved across the spectrum when I replaced the internal switching power supply of my streamer with a Teddy Pardo LPS. There are so many choices and combinations that you’ll want to audition to really know what sounds best to YOUR ears. I don’t recommend using a computer as some suggest, mainly because they aren’t purpose built for music streaming and will add noise to the signal path due to their power supply and extraneous components you don’t need for music. 

$300USD streamer...Cambridge MXN10 coaxial to

$9000 DAC in the Audio Research Reference CD9 cd player

Sounds wonderful.

If you go separates a 50/50 % split is recommended. Good all-in-ones are the Tambaqui, Aurender A20 and Lumin P1 (I have a P1 and it has more features than the other 2 all-in-ones I mentioned, and its cheaper). One thing I've discovered recently is local high-rez file playback (in my case via a Lumin L2) beats streaming and CD playback easily, and gets CLOSE to my vinyl setup. IMO it won't be long before digital becomes indistinguishable from analog.

Used Lumin X1. 7-8k. Great pkace to start/stay
Aurender too. 

A lot of info these forums helping w/ the whole chain. Router/swiches/fillers/cabels all help and are important to SQ. Worth the cost.
