i've not been impressed by any 'jitter suppression' device i've tried (the dip - although an older version and a bheringer ultramatch pro - again not the current version). the only ones i've come across that are reputed to work well are the apogee big ben and the now defunct genesis digital lens. the latter pop up on audiogon for about 500 bucks every so often.

afaik the common factor between the two is a buffer which is used to store the data so it can be reclocked completely.

at the end of the day though the best solution would be to improve your transport - either by getting a new one or modding it with a new clock and better power regulation.

i have an old bheringer ultramatch if you want to come to some arrangement - you may have better luck with it than i did.
