LOL, I’m going to treat this as a trick question, since you know the answer is Pendant. 
Seriously though, I’m only saying this because there is a huge amount of synergy between the Pendant and ZMF headphones, and it also works wonderfully with my Stellia. And since you just bought a VC, I bet that ZMF will give you a discount on the Pendant if you email them. I waited several weeks after I ordered my VO before I decided to also get the Pendant, and they were nice enough to retroactively give me the bundle discount.
But if you want to stick to a Feliks amp, I’m sure @MRHifiReviews and others can give you their impressions with Focal and ZMF headphones. Marcello made a really interesting video comparing the Pendant and Elise.
