Depending on your budget
I sell my self Denafrips products ,I hear a lot of equipment to the many audio get togethers I have gone to over the past 2 years , in the $3k range the Pontus Gen 15 is not a bias it is far better built then anything in the $3k price class but $1k less
it’s the Ex Venus 12 , The T+Aw200 dac is very good with a lot of tuning possibilities , as good or better then the New Denafrips Terminator 15,
or Holo May KTE dac the Mojo. Sounds good $7k on up has at least some inputs , I2S inputs should be standard ,many people have nice digital transports like Esoteric, Jays Audio which allows you to play SACDs k and many people use a DDC I2S is the best soundin digital input currently, even the LTA aero which I think sounds nice with the 2 tubes missed the mark , even they agree ,the next modification will have I2S . DDC to clean the incoming signal from their computer or streamer with absolutely make a improvement , look at the Chord Dave pretty $$ expensive to most then has a ad on reclocker that is what makes it special combined together. That’s my opinion and many others , PS audio set the standard on the pin out that most cable makers are now using for I2S .
