With all of the talk lately of the Aegis I should prolly re-post my Aegis review I did way back when. Granted this is a review of the DIY version, but apparently the ZMF version sounds essentially the same, with some nice quality of life features thrown in.
If you just want my down and dirty, quick opinion of the Aegis, FF to 18:20
As the unit in @Monsterzero’s video is the one I have at home, I can only confirm that “this is a brilliant amp”. It truly stands unique in its character, having a magnificently large soundstage and a very refined presentation. I especially love it with the Tungsten and Caldera, but honestly everything I ever tried with it sounds great.
