2005 CES大奖
Newcomer April Music impressed two SoundStage! writers with its Stello-brand products in 2004. Doug Schneider wrote that the Stello DA200 DAC was "rich with features and approaches cost-no-object sound -- both for a bargain-shopper’s price." About the DP200 DAC/preamp, Tim Shea said, "That you get all the DP200's flexibility, build quality and astounding performance for less than two large borders on the absurd." Accepting the Best Product Debut award are (left to right) Adam Sohmer, Simon Lee, Um Tai-Won and E.J. Lee.
