Butler, after living with the amps for a while now, I must state that they are better then any older Jadis amps I ever heard, regardless of the price or the power rating. As I mentioned before, they retain the usual Jadis seductivness in the midrange while adding staggering dynamics, top to bottom extention, incredible resolution and inner detail retrieval. I must say it is a new era of Jadis, thanks to Jean-Christophe Calmettes - the new ears of the company.
