Anthem STR vs Benchmark AHB2

I'm leaning toward purchasing a pair of KEF R11 speakers (8 Ohm, 90 dB sensitivity). I'm considering the following and looking for feedback -- I realize that having the ability to A/B the following is likely rare, but open to all feedback. Additionally FYI, I'm leaning toward pairing an Anthem STR preamplifier for 2.1-channel processing. Will then be leveraging the Home Theater passthrough of the preamp for 5.1 surround -- surround processor yet to be determined (preferred eARC compatible -- open to suggestions).

a) Option A: Anthem STR Amplifier (400 Watts/channel into 8 Ohm, 121 dB Sensitivity) vs two (2) Benchmark AHB2 amplifiers configured as separates in mono (380 Watts/channel into 8 Ohms, bridged mono, 135 dB Sensitivity)

b) Option B: Go with either Anthem STR Integrated Amp+Premap (200 Watts in 8 Ohm, 114 dB Sensitivity), or, a single Benchmark AHB2 amplifier (100 Watts into 8 Ohms, 132 dB Senstivity, +Anthem Preamp).

Mostly interested in the perceived sonic differences (if any) between the various options with the paired speakers. Additionally open to other suggestions.

Thank you!

Kef say their R11 is 90db and able to run on a 15w amp, and bi-amp’able

I’d be looking maybe at the "Class-A" Aegir on the mids and highs, and maybe the Vidar or ABH2 on the bass, with a $39 Sys on the input of the louder amp so you can balance the gains out, then your pre is still the master volume.

PS: Never bridge amps, all you gain is watts, everything else takes a hit sonically.

Cheers George
