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..

@Verdonaudio . I am sorry to hear the Aethos could possibly struggle with my speakers, didn't realize the 805s is considered a low impedance speaker?? The Rega was on the top of my list..

@jerryg123 yeah I'm not surprised there are issues with NAD, I'm pretty disappointed in the direction nad went since my T752, especially leaving A/A/B class amps for D

It was not from a review, it is in the manufacturers stated specifications.  

Power outputs at rated 230/115 V supply voltage:
125 W RMS both channels driven into the rated load of 8 Ω
156 W RMS both channels driven into 6 Ω
Note: Continued high level use into 6 Ω may cause the case to exceed 40 °C above the ambient temperature and activate the thermal shutdown.

The min impedance on the 805 D3 is 4.6 ohms so not particularly low but low for pairing with this amp, problematic.  

Ahhh.. thank you!!! Pretty disappointing, especially since I had a line on a lightly used Aethos for $3600(I believe it’s a demo)but so glad you told me, saved me possible grief later on👍. I took it for granted being 125wpc from a class A amp in a high end amp I’d be perfectly fine.. Shows you what I know lol..

Well with the M33 and Rega crossed off my list in open to any other suggestions that would work for me with the 805D3s..

Dear verdantaudio

If I may piggyback ... I am thinking of the Naim Mu-so 2 for my living room, as a one box solution to stream Roon. I've heard that it sounds great. Your opinion? I don't mind the lack of stereo separation that speakers would offer (wife doesn't want freestanding speakers).

Thanks!

 

@capt57 I would look seriously at the Supernait or a Uniti Star or Nova with a major caveat that they are out-of-stock.  The absolute power rating isn't that high but it is plenty of power to drive those 805s and tonally is warmer and a brilliant match.  The only issue is that they are out-of-stock at the distributor.  The Uniti Star looks like inventory may be in soonish.  The Supernait has no estimated delivery date. 

An alternative at $6299, the AVM CS 2.3 is an all-in-one streaming unit that would definitely do the job.  AVM is tonally quite warm and a brilliant match for B&W.  This new unit has been worked on a long time to make sure that it is virtually bug free.  My guys at the distributor have been running it for a few months without issue and have been super happy with the software.  Silver and Black are in-stock and it would be a nice option for you as it has similar features to the M33 or the Uniti Star. 

If I can think of something else I will mention it here.  

@patrickdowns The Mu-So is in-stock at the distributor in three colors.  It is a nice unit.  I feel it is MUCH better than a Sonos or a Pulse but has the natural limitations of a single box.  If you can live with that, it is a good sounding option.
