100+ Head-Fier
Having owned it too and running it with some of the best tubes recommended for it, my Burson was much more energetic sounding and engaging.
Not that the Mj2 sucked, but it just didn’t click with my Audezes and Hifiman compared to my Burson at the time.
Would you say MJ1 is worth it used at ~300 vs. the HPA-3b?
