Well remotes are magnetic (a lot more magnetic than anything you’ll find on such a fan) and they’re designed to attach directly to the products. Although I’m no expert, seems to be working just fine though.
Ah, but MJ3 has no remote, magnetically attachable or not. So, not helping with the nervosa?
Going to be smooth and lovely is my guess/
Schiits remotes** i meant, and you are right. I’m sure they would have some type of disclaimer or warning being that we stack these products and it’d be a very easy mistake to make. However, everything seems to be just fine so far.
Well, there is no consensus, but my experience has been that it is good to leave 50-80 hours for burn in. The initial rawness and treble dryness/intensity has definitely improved/smoothed out. For warm up I would say 30-60 mins. Don't expect huge improvements, but if I had to quantify, I would say jumping from 80% performance level to 100% in both cases.
I will let you know my impressions of them once I have them in hand and spend a few hours listening with them. As far as the Caldera, i doubt I will be purchasing one in the near future. Maybe down the line though
. I would most likely pick up a Yggdrasil before a Caldera purchase. 
Caldera is great on the MJ3. Bass is very impactful with good weight. MJ3 really brings out the fabulous bass the Caldera is capable of. Mids are nice and sweet and treble is fine too. Upper-mids and treble can have more space and better resolution/more details on other amps as the Caldera is able to scale higher, but fun factor and a joyful, kicking bass is a great experience with MJ3-Caldera combo. Recommended pairing.
I have had the MJ3 for a few months now and have it paired with a BF2/64. I listen to either Amazon HD from my pc, Flac files and or cd's. I own the Atrium open and currently have been using the BE2 perforated hybrid pads...They have become my favorite pads with my Atriums. They sound absolutely amazing on the MJ3. The MJ3 has more than enough power to drive them. It gives them just enough of a little extra rumble on the sub bass to feel it. The strength of the Atrium's as we all know is their midbass. It gives a solid punch in the midbass..The soundstage is wide, pretty high and deep..It also gives you that holographic feel...I listen to a lot of live music and if you have a really good recording of a concert it is like you are sitting center stage a few rows back. Them MJ3 is definitely my favorite ss amp that I have listened to the Atriums on. If you have a chance to hear this pairing you will not be disappointed one bit at all. As for the Caldera I cannot comment on how they sound on the MJ3, I have not got to hear that pairing.
MJ3 is a good choice and a unique amp. Great value too. When choosing pads for the Caldera I cannot recommend the thick pads enough.
I demoed the Caldera for a week and compared it to my Elite with the MJ3. I don't personally think they are the best complements since they are both musical, high-end, open-back planars. I felt like I couldn't justify owning them both. For me, the Atrium Closed made much more sense to have as a counterpart to the Elite. If the Caldera had won me over, I would have probably sold the Elite. The outstanding comfort of the Elite was the tie-breaker in my case. That being said, if I had owned the Caldera first and then got to demo the Elite, I probably would have kept the Caldera. There are both excellent options.
