been a devotee for about 5 years now.The great sound and ease of use of these products is great. The designer, Michal, is an audiophile at heart and provides Chesky with gear, among others.. very smart guy. I was a former benchmark and grace user.. no more.
mytek really wiped the floor with those two.. they sound strident and lackluster in comparison. mytek costs less too..

there are some high res comparison files on the website..
