Help me clarify these doubts on Preamps/Pre Phono

Ok, it's time to get a good Pre/Pre Phono Combo.
Unfortunately I have not everything cleared: I gotta choose among:

1. ARC Ref. 2 MKII + ARC Ref. Phono;
2. Aesthetix IO Signature with Volume Cont and 2 power supplies (directly connected to the amp);
3. ARC Ref. 2 MKII + Aesthetix IO Signature with 2 power supplies;
4. Bat VK51SE + Phono VK10SE;

Now, assuming for absurd that those combos have the same price range (used, obviously), what would you choose and why considering you have to coordinate a Colibrì 0,65 mv at 500 Ohm optimal load impedence?

Thanks everyone
