Here is the principle. It has a Hawksford type driven cascode. I have improved that circuit in the meantime.

Speaking of amplifiers, this one has caught my attention.
I'm hoping I'll build/hear one at some point.

The beayty of the current feedback of the monster is the fact that you inject the feedback in the same devices thta works with the signal....the gem is af very traditional design with a ltp input/feedback configuratio. I am100% confident that the monster current feedback type holds much greater potential....it has simply much less smear and far greater clarity..

Ricardo, the relays are for switching between the driven cascode and conventional ground refferenced cascode. We found that the driven cascode has more slamm and definition in the bass. Well, inside of the 8W it can throw around.
I find the GEM unusual, but honest i do not get the point.
MiiB. one advantage of current feedback is that when a heavy signal hits the feedback node it is not limitted by the constant current of a long tail pair, hence the slew rate is much higher.

Sure, it has normal gain and a Fet input so current draw in minmal.
