Integrated amp to replace Nu-vista M3?

any ideas of an integrated to replace the M3?
My front end is a linn ikemi.
speakers are the verity audio fidelio

I am considering:
bat vk300x
bel canto evo 2i
pathos twin towers or logos

I listened to the rowland, bat and m3 at a store with eqipment I was not familiar with.

I listened to a new jeff rowland concentra 2 but I preferred my m3 over it.
To be fair, this unit was new, however even new I should have known right away if it was for me or not.

The bat vk300x seemed sweeter than both rowland and m3, however the M3 seemed to have more bandwidth with a deeper bass than both the rowland and bat.
thanks.
