Your Fulla 2's volume knob is smoother (and for my ogre-sized finger tips... more controllable) than my Magni 3's pot. My vote: Modi/Vali2 combination... for something a little different. I'm very very pleased with my Vali's performance and it does sound different than my Magni... for what it's worth. Modi-3 or Modi Multibit? Ooof, I'll reserve judgement (pssh, for ripped CDs [16-bit, FLAC], it's an excellent pairing for me). Unless your headphones need more oomph, I suspect your Fulla will be awesome enough. My 2 cents...
