Tidal HiFi/medium tier ->Equalizer APO with just a tiny bit of tuning -> a xDuoo stack of USB DAC + hybrid tube amp -> Sennheiser HD560S
Definitely a little bit of overkill. But still overall fantastic budget, and do it all setup. Competitive shooters, movies, and music all sound fantastic.
My next goal is a multibit DAC + tube only amp -> something like a HD 6XX. Or maybe a good solid state -> planar magnetic headphones.
