Hi Jeffkad,
In my otherwise neutral playback system as described above
the scorecard on the Cary Audio 306 Pro vs. the Esoteric K-
03 reads like this.
The Esoteric trumps the Cary for outright resolution, sound-
stage depth and object edging, treble extension and bass
depth.
The Cary trumps the Esoteric for image specificity and
density, mid-bass weight, overall musicality and engagement.
I was very surprised at just how different these two fine
machines sounded considering they are both fully solid state
designs with large linear power supplies and both running
four quality DACs per channel.
There is much more to the story including a rather unusual
finding with the K-03 - which I will write up in due course
in my audio blog.
