A bit of a change of perspective/focus from a senior citizen.
1. Try some MIT Matrix 60 or Oracle level speaker cables between your existing amp(s) and the Magicos, which need a little something different to keep from sounding sterile. $2K-4K. I heard some S5s with even some good Constellation amps - very 'stiff' with no life at all. Absolare sounded great but not sure its enough power for your goals.
2. A couple of more budget friendly beast blasts from the past - Audire Otez, or Musical Fidelity kW500 or 750. Probably $2K-4K
3. Old school Krell FBI or new school Krell KSAi-400 Latter not near $2K-4K. :-D
I know.... [most] all budget and a bit dated. As a newer/costlier suggestion, I saw an Audionet Humboldt on Ebay-England (220v though).
