The VAC should be holographic and extremely well-balanced on the Eidolon Diamonds I imagine - and would be my personal first choice by far. Having spent a good bit of time listening with the PHI220s on them I have to imagine the 300.1 would be amazing. I can tell you that the VAC 220s were a better match to my ears than the Boulder amp in almost every way (though that likely depends highly on what type of music you listen to and synergies with associated equipment as well).
For what its worth, a lot of people who have lived with the CAT/Diamond combo speak highly of them but I have not had any extended direct time with the combo (I'm sure they will be chiming in shortly).
Will be curious to hear your selection but congrats on what will likely be an exceptionally musical system!
