Difference between Marigo apparition 5.5 and 5.7

Has anyone tried and/or discovered any differences between the above two digital cables please?
no- I just went for the 5.7 Sig and didn't look back- a superb digital cable- you won't be disappointed...
Sutts, are you using the balanced or single ended? If single, bnc or rca? Thanks.
Do they have a web site ?
Re website. Yes, Elberoth2, they do have one, address is: www.marigoaudio.com. Unfortunately, It doesn't contain any info re the older models; I've tried emailing but not had a reply to date. Muz (Can't 'phone as I'm based in the UK).
