I think, if the other stages pass wide range audio, you can boost the fidelity some with EQ, but I would not push it to hard. In most cases, you dont really need to, you just need to correct for a crappy microphone and your voice. I think we have all heard people who sounded great running stock rigs like the 32V3 and a decent mic. I dont remember who it was, but I do remember someone just like that, stock 32V3 and a Sure 55s or something like that. I dount think he would have sounded better on a broadcast rig.
But the mod iron can alter your voice, some need less bass, other people sound better with some boost. I used to run a CVM5 mod trans, and when I got the RCA transformers, sold the cvm5 because it sounded so poor compaired to the RCA. I think the trick of running everything gently helps, gentle EQ, gentle compression, gentle modulator output, gentle final power percentage, gentle modulation percentage. Its best it build big and run it easy, with as much audio power output avalable as rf power input.
