I've both setups with MS and yes with Dave it's better in general but on TT2 I feel never the urge to think damn I miss the Dave, like there's so much to respect with TT2 that it is satisfying well enough to stop bothering about the differences.
On occasion I listen to mojo1, mojo2, and then that's OK too, different again but lovable still, more than RME adi2 dac FS.
Dave HP out (no mod) starts to suffer when playing planar-magnetics loud, I'd suggest HPamp.
The Focal Stellia is less power demanding and very fine on Dave playing loud.
As expected TT2 does a better HP section for more (reasonable) demanding HP's.
I lost interest in HQ player. It is soo promising and a super cute toolbox but... it is veeery easy and fast to fekkup your parameters and sooo difficult to find a resting point named "I am there, now I'm set". Going back to bit-perfect once in a while to compare .... and you're off again fiddling the million HQP parameters.. sigh.... endless not-quite-perfect. Sometimes I think of bit-perfect as black'n'white photography, don't add colours because anything you win there's a flip side of loosing character.
