Monoblock suggestions to compare to SimAudio Moon Neo 400M?

When I read this forum, I am amazed at the recommendations you all give, because I feel like I've read so much here I should know most brands. Yet, nearly every time, someone makes a solid recommendation of something I've never heard or read about.  So, I've almost settled on the Moon by SimAudio Neo 400M monoblocks as my amps, but do you have suggestions of others to consider?  

PS Audio BHK Signature Preamp
PS Audio Direct Stream Memory Player
PS Audio Direct Stream DAC
Sutherland Phono Loco phono stage
Luxman PD-171A turntable with Jelco 850 arm and Hana ML cartridge 
Wilson Sabrina or Yvette (TBD)

Other amps I've considered:
Bryston 7B3
Bel Canto Design RF600M
Van Austin DAVE SET 600
Benchmark AHB2 (pair)

I've seem some of you dig in and really research your answers, and I want to say "thank you" for the time you often take.
