New integrated amp recommendation

I’m looking for an integrated amp to drive my Ohm 3000 speakers. I’m currently using a 45 watt Yahama int I had back in the 70s and it plays loud enough, but lacks bass punch.

On my short list is the: Luxman 505u, Sim Neo340i, Ayre AX-7e, Hegel 160.

The Ayre is the lowest on the power spec, but I think it will be sufficient for the type of listening I do.

I owned the Ayre AX-7E and sold it and bought a Luxman 505UX and was very happy. Using with Harbeth SHL5 speakers which are medium efficiency.
Austinbob- how would you compare the sound of the two?
