Keep it simple if you can. Less is more.
Get a used DAC/Headphone Amp that will also work as a preamp (ie. Benchmark, Matrix, Emotiva, etc.)...use its balanced outputs into balanced inputs of powered studio monitors. If you go big on the monitors, you may not need a sub.
However, you would have to sell some gear but it is decent stuff so that should be easy enough. The new DAC would be $200-600 used and Yamaha HS8 are about $700/pair new.
