Presuming you are fond of the ARC Ref 3 the path of least resistance would be to audition the ARC Reference 210's. They're a significant improvement over the original REF300's. The others you mention are some very best sounding amplifiers available. However in terms of synergy each of the designers mentioned has a bit of a different perspective &/or approach. Mileage will vary on if you feel the amalgamated sound is to your liking.
If time permits please do post a follow-up. Id be most curious to hear how your final solution turns out.
