Hey , I owned one of these years ago . I am guessing most here aren’t real familiar with Grace products . It sounds fine . Only way to tell how it would sound in your setup is to pick it up . Being a pro dac it is not going to deviate from flat too much . I have been looking for a good priced used Grace m905 monitor controller for years . No one wants to start a no reserve auction on one . What other dacs have you tried ?
