Which integrated amp for better musicality - Parasound Hint vs Primaluna vs ???

I've been having a blast looking up threads and doing some research but my dilemma is this - I want to get more enjoyment out of my music (don't we all). My Anthem and Oppo setup honestly sound great but I can't help but think that maybe I am missing out. I am thinking of upgrading some of my gear by either adding an integrated amp or separates. I'd love to hear some recommendations. Based on some reading, I am considering: 

1. Parasound Halo Integrated 6
2. Primaluna Dialogue Premium or Premium HP

My current setup is as follows: 

Oppo 105D
Anthem MRX 510 AVR
Ascend Acoustic Sierra RAAL Towers and Horizon Center

Any recommendations or thoughts would be greatly appreciated.
