if you look to a good analog but transparent expender (not like the Requisite )
look at the NTP 179-160 it's an expender/comp /lim built by NTP mostly for broadcast use, but also used in some mastering room
in my sense they're really underrated tools,
they're really good for invisible and delicate compression, and also for expending trantient
the limiting is quite invisible too
the only minus for me would be: no side chain, and a very light loss of high freq but what can be good sometimes
they are greatly built
and not as expensive as the requisite...too
but good luck too found a pair of modules (to the german danner size ) or a 179-170 (the 1U rack version)
what is nice too is that you can link 10 of them what is too much for a suround set up of course, but who can the more can the less
i remember once i used them for a compilation where some tracks had been over compressed with some multiband shit
and it had made some great things re giving dynamic life to the songs
