I won’t go into too much detail yet, but I just got my MJ3 yesterday and had my first listening session with my Yggdrasil A2 and Meze Elite. First impression: very impressive. I let the amp warm up for about a half hour before plugging in the headphones. I used my eclectic “test tracks” playlist on Tidal to sample out a lot of different types of music. The first thing that stood out was the level of resolution, like many owners have mentioned. I feel like detail retrieval is at least a solid step above my other two amps, the Cayin iHA-6 and SW51+. The increased resolution/detail is not forced on your ears though. I was able to easily switch between relaxed listening (leaning back) and really focusing on all the extra info being presented (leaning in). Detail is presented very naturally without boosted treble or any other tricks. The other thing that stood out in my first listen was the bass. Impact, texture and overall bass detail was excellent. I could follow the bass line in any song with ease and make out all the subtle nuances that are easily glazed over with other amps. I can definitively say that I have no regrets on my purchase of this thing. I’m looking forward to trying it with my OG Auteur as well. My gut feeling is that the Yggdrasil A2/MJ3 is a going to be great combo. I imagine it will only get better as the amp settles in and I get more accustomed to all the things it is doing.
