I would agree - It is - One of the headphones...

I'm a confessed Raal fan, bought my first set of SR-1a from Justin and coerced Doug into making me a custom transformer.  I cannot in good faith spend that kind of money on the Immanis, but I did just pick up a pair of the little brother Magna.  My review is forthcoming, but based on how much I liked the R-1a and the CA-1 I expect I will enjoy this new tarted up model, too.

Probably needs a good transconductance amplifier.

They basically convert input voltage to output current.

This is far from a review, but my impressions from the first few days of listening to them through Doug's Bridgeport transformer are overwhelmingly positive.  These things are too expensive but they are the real deal.  All I really care about is detail, so I was willing to give up bass extension in the SR-1a and, to a lesser extent, the CA-1a, but here there is no need for a trade.  They are every bit as detailed and incisive as their siblings but with very present bass extension.  These do not struggle with an open "B" string on an electric bass, which is ~30 Hz, and that is fucking impressive for a nearly massless ribbon you strap to your head.  I'm awfully impressed and therefore given to hyperbole, but they might be the best headphones I've ever heard (I have not heard the HE-1).  They are certainly my favorite.
