Well I will answer my own question, as I purchased the Blue Jaspis for my Senn HD580 several days ago. I can tell you this the BJ will never be coming off my Senns!
The cable is a full 3 meters long, the body is bright blue and the right/left branch cables are dark grey. The cable is about as thick/stiff as TV coax cable, some people may not like this but it doesn't bother me, cable is double sheilded. Treminated in high quality 1/4 gold connector.
As far as sound, the treble/midrange is slightly more open
and detailed, yet still silky smooth. I am using Creek OBH 11 and Grado RA-1 headphone amps. The biggest improvement is to bass response which is noticeably deeper and more forceful, makes overall sound more dynamic. A very worthwile
improvement for $90 from headroom, I would recommend this to all Senn HD 580/600 owners.
I am amazed how cheap the Senn HD 580/600 can be purchased now here and other internet sites. Perhaps Garfish can let us know his impressions of his Blue Jaspis.
