Rega and Simaudio are fine choices and I have owned both units in question as well as the NAD M33 and it's life was very short in our home (quality issues).
Rega Aetheos, Simaudio Moon 340i or NAD M33 for B&W 805s?
I know picking a integrated amp by it's depth is wrong BUT I'm stuck with this situation (depth of my cabinet is 16½"). I have B&W 805 D3 speakers and presently running them with my old NAD T752 amp (have a newer Denon but much too thin and bright for the 805s so I brought back my old NAD). I mostly listen via turntable and streaming Amazon HD thru my Fire Tv, I plan on getting a BlueSound node if whatever amp I get doesn't have streaming capability. Power wise these 3 should be just fine but with absolutely no high end shops anywhere near me I'm stuck choosing by users & reviewer's take on these 3 amps.. My main worry is getting a amp that's too bright for it would definitely be a bad match for the 805s.
I'm hoping someone here has or heard these amps with the 805 D3s and could give me their thoughts and opinions..
