If you have a ps audio preamp, why wouldn’t you go for the ps audio DS jr or DS sr dac? These dacs are far superior to the benchmarks in sq, Ethernet and i2s capability, and fpga based. I had the DS jr for a couple of years and then went to the DS sr with the bridge II card. Don’t use usb with or without the so called tweaks to try to make usb decent sounding, and go with a dac that allows you to put your music server (pc/Mac, 3rd party) in a separate room and use Ethernet (with or without fiber if your network is noisy).
The DS jr will get you 70% of the quality of the DS sr for about $2200 used or find a used DS sr for around $3500 used
