Depending upon your budget and musical preferences, and of course your listening environment, My two top preferences are; - - - - - - - -
PRIMA LUNA EVO 400 - either integrated or monoblocks (coupled to their fabulous top rated preamp) - EXPENSIVE but worth every penny
Second choice - AYON TITAN MONOBLOCKS
In this case if you can afford it, I would unquestionably go with a complete system of AYON components. Virtually world class in every respect - VERY EXPENSIVE but set up with the right speakers; - - the best the world of audio reproduction currently has to offer !
These are both offerings that you will be able to live with for a long time of musical reproduction satisfaction and unrivaled reliability.
Naturally, everyone has their opinion, but this is mine !!
