I heard a Tri-Vista CD, Tri-Vista amp (with big powersupply box) and Nautilus 802s.

A more limp and flaccid system I have not heard. Even my rotels/B&W grooved better during their off days (and are now significantly better than that). Supremely detailed, but no music. Hopefully the Thors and Proacs added more life to the system  you heard...
