One thing i have noticed with the bose, well in my case only, mine only skips/jumps when cold as such, think its to do with the condensation build up betweent he disks, allways find if you remove all the cd,s hte night before, then let it warm up, works perfectly, or if not take the cds out say in morning give little wip and all ok, dont no if anyone does or has experienced this ......., but normally works for me
