Which dig source,passive front-end,ICs,amp combo?

Irregardless of loudspeaker choices, sensitivity or efficiency, (I know. Loudspeakers should be first consideration, typically), what are some options or combinations I should consider, which you have found offer the highest levels of pure "passive front end approach" fidelity and synergy?!
I tried in vain years back - trying many several different digital sources (run from analog outs), passive preamp options (including dig direct from DVD pours, trim pots,high ended passive pre's), Interconnect combos, and amplifier choices - and always felt disappointed,from the subsequently subdued dynamics and constricted soundstage from the sound! (My speakers were Sonus Electa Amators, Thiel 2.3s, Infinity Preludes, Dunlavy SC1s, and other dynamic driver loudspeakers) Thus, I have stayed with the active preamp route, as I enjoy rock, dynamic world beat stuff, movies n such, played through my systems.
I've recently read that the analog outs from digital source components may now be more "passive friendly(??)" over past few years, and that some are reporting very good sonic results using the passive front end approach?! I'm just starting to get back into high end 2 children, and would like some dirrection. ..I'd even consider loudspeaker options after figuring which gear others find work great together in passive config.
Thx for your opinions n suggestions.
