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

Hi, have you considered a Wyred4Sound 250 watt integrated amp. I love mine, I have speakers with 15inch woofers, and I think netflix is doing structural damage to my house. The amp is dynamic, powerful and pretty smooth, but not dull. Plus seems to be pretty resilient to loads, its like 460 watts at 4 ohms with excellent protection circuitry. Worth a look I would think, same price range as krell s300i. I see that some talked about Peachtree 300 that is very close, both use ICE amps. I have never heard the Krell s300 but do read reviews, it might not be right for Klipsch horns.
Good luck!
jffyg, owned the Wyred4Sound STI-1000 back in '09. I considered the Peachtree Nova300.

The Belles Aria is in your price range and plays wonderful "Music" with Klipsch speakers...Nice MM phono stage too. On a side note....The Lounge phono pre amp is an outstanding product for $349..... Highly recommended. New Record Day loves it so much..... I bought one and love the weight and detail it adds to vinyl....
