Question RE ML336 vs. Omicron l & ll vs. Pass X350

I have a Krell FPB. I am looking for a richer, warmer sound with good bass performance and good dynamics. Which of the three amps listed above will most likely provide that with the following system:

B & W N802's
Blue Circle 3.1 Galetia Preamp
Krell MD20 Transport
Kora Hermes DAC

Please provide any feedback with these speakers and these electronics or any applicable information on these amps
Don't know the omicron, but would recommend the Pass!
I'm using an ML 335 with Magnepan 1.6QR's. It offers
excellent bass control, transparency and a soundstage
with three-dimensionality. Highly recommended.
