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
