Which Integrated with Power,Current, and Bass

In your system, at a show, in a showroom, or at a friend's, what integrated amplifier have you heard produces solid low end (bass), highs etc consistently with whatever speakers you heard it with?  I'm looking for a solid state integrated in the $2500 and under range that can accomplish the above with my Klipshch RF 7II which although seemingly efficient are a challenging load dropping down in the bass region below 4 ohms.  I listen mostly to classic jazz with a little rock, r&b mixed in.  Or, which manufacturer have you heard consistently produce integrated amplifiers producing solid low end with whatever speakers? caveat: I don't like anything lean or that tends towards lean!  Would love to try an integrated that doubles down, but that seems out of my price range with the exception of the Krell (used).  Need a fairly smooth amp up top because the Klipsch horn can sometimes get harsh. Not interested in tubes though. Currently using Anthem 225 but not convinced.

Have thought about:
Vincent SV-237mk
Musical Fidelity M6si
Yamaha A-S1100
Parasound Hint 6 or Halo
Krell S-300i
Musical Fidelity A5
