Rega Aetheos, Simaudio Moon 340i or NAD M33 for B&W 805s?

@Verdonaudio I came across another possibility, it seems to have plenty of power but not sure if it will the same lower ohm issues as the Aethos?

Musical Fidelity is wonderful gear but slightly forward in terms of the sound profile.  It is not a brand I would match with B&W.  The other issue is that it is very difficult to find lately.  

I was thinking that McIntosh almost assuredly has an integrated in this price range but it might be too large.  

Are you willing to consider a hybrid class D?  Tube input stage with class D output stage.  I have an amp that is exactly 16" deep and it is 100w into 8 ohms, 150 into 4 ohms.  The Canor AI 2.10,  I also have a demo of the AVM Evolution A5.2 integrated which I think is 185w into 8 ohms.  It is 16" deep including nobs and binding posts.    I have used both to drive Vivid Kaya 45s and they have a min impedance of 2.8 ohms so much tougher than the B&Ws. The Canor is $4K.  The AVM is my demo.  

@Verdonaudio first off thank you so much for your help, it’s been invaluable!! And yes ALL Mac’s are too big lol, funny but their manufacturing plant is actually a little less then a hour drive away from me.. Sadly the Canor’s 16" only leaves me a ½"in the back for power plug, connections ect, way too tight so that won’t work either 😢

Strangely in my research of the Naim Supernait 3 some users said they found it on the thin sounding side?? Have you heard the Naim Supernait 3 B&W805D3 setup?

I have not hear the Supernait with the 805 D3.  I can't answer how that would work out.  I am making a recco based strictly on a paper matchup.  

I found the depth of the AVM, it is 325mm or approximately 12.8".  I know if has redundancy with the CD player and it is a bit over budget at $6300 but it does include a good DAC and has built in streaming.  

I am largely out of ideas beyond that.  

Thank you verdantaudio, I totally appreciate all your help and advice!!  ;)
