The reason people have a cult fanaticism around the "super hard" 5AR4s is due to the lower plate resistance in very good 5AR4s. With a DAC you are getting zero benefit from a tube that passes 250ma of current better as you are using a tiny fraction of that.
Tubes are cool, but most people do not know anything about the actual reasons behind great performance.
Relax and enjoy the sound. If your real desire is better performance you should consider Schottky diodes.
