I've been auditioning the EVo over the summer against other amps and think the high ratings are spot on. If anyone is a real 'detail' listener and likes ss, then the EVo with the B.C. Pre1 pre-amp will shut down anything costing 3x the combined price. Stunning quiet and transparent, smooth - not harsh -- subtle harmonics within notes leap out of the speakers, particularly on electronic music of any kind. For my own personal tastes, I'm buying the EVo, but mating it with a Presence Audio Delux tube pre-amp. Dead quiet, detailed, but with that touch of life tubes bring, particularly to any acoustical music and vocals. That's the only thing I found lacking on the EVo, a tad dry in the mid-range. There are reviews of both these boxes coming soon from soundstage and stereotimes. The guys at stereotimes are mating the EVo with the new Talon Khorus speakers (which go down to 20kHz) and find the EVo is detailed and articulate all the way down.
