Hello,
I have tested some of these DACs. There are basically two types of DACs. R2R which sounds like analog but also a little mellow unless you spend over a thousand like the Denifrips Pontus. When you go to a chipset based DAC it sounds very detailed and airy but less analog unless you spend the money. If you have tubes I say go with the RME or Schiit. If you have SS you can go with R2R as long as your system is not too warm. RME has an adjustable EQ so it should be good for everything. Try to get something you will lose the least money on when you sell it because you will be upgrading in the future. I would forgo the SBooster power supply for now because you will not get your money back and they are voltage proprietary. DACs are going to improve the most over time. You should look for used. This way you will lose the least amount of money.
