First a disclaimer: I'm an MIT dealer.
The system you describe is a genuine classic and is capable -- even now -- of near-SOTA performance in all areas except deep bass. The change I'd suggest, especially in terms of bang-for-bucks, is to upgrade your interconnects from (I'm guessing) MIT/Spectral 350 Series to MIT's current Oracles, such as the V2.2. Possibly upgrade your Digital cable at the same time. If you'd like to discuss options, you can call me toll-free at 1-888-737-4434.
