I have this preamp for over a week in service and have already ZIG plates with an ancient ITT turntables and Adobe Audition digitizes (have also 2 older turntables tried). It works just great !! And I have a precaution, the ground terminal from DIN connected> RCA cable. It works even without ground terminal (and without quality difference). Turn off the power may be important - because of the battery. So - I am more than satisfied !!
