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.
