Best integrated amp for A Z Adagio speakers

Im using a sim i3 with mine,and it does everything above mentioned.Looking to stick with sim and do a i5.3 evetually.

The Adagios are very musical speakers. They work well with both tube and SS components. I would look at a Krell integrated or Pass Labs. Leaning towards a more resolving, detailed signature. You dont want to add too much relaxed base to those speakers. A well controlled bottom end will benefit the representation of lower frequencies better in regards to the adagios. I would focus primarily on finding a tube or SS that can achieve this. The mids and highs as great regardless of choice.
