Should I get the Moon 891 streamer/dac/preamp for my Moon 861 amp? Or separates?


I own a Moon Audio 861 amp. Right now I have a McIntosh mc12000 preamp and a eversolo A8 streamer. With Focal N1 Sopra speakers (that I am happy with). Obviously, with the streamer I am not getting the best sound I can from my Moon amp. 

So, I decided I will sell my McIntosh M12000 pramp (it's so beautiful, it hurts to let go of it) and use the money for a dac/streamer/preamp. 

I was thinking about the Moon 891 streamer/preamp/dac. It makes sense because I have the Moon 861 amp. But 25k is so much money, I was wondering... would it be better to use that money on a nice streamer and dac instead? Like a 10k on a streamer and 10k on a Chord dac? Or would it be best to stick with the Moon 891 for the synergy between that any my Moon amp? Looking to get the best sound I can from my amp.

Simaudio also has the 791 Pre/DAC/Streamer which is $16k vs $25k for the 891 so that might be another avenue to explore (I don't know what the differences are).  I suspect that mating either of these with your 861 would produce detail in abundance and you would have a great two box solution.  A nice side benefit is that the Sim integrates easily with TV with HMDI ARC. 

 

Quick question for you @mgrif104. You write: "If I were to do it over -  I would pair their 800 series preamp/DAC with the 761 amp which I own already." Are you currently using the 791? Did you (or anyone else on this thread) ever compare the 891 to the 791, holding the 761 power amp fixed?  Thanks.

I am not currently using the 791 - I have the T+A SDV 3100 HV (with preamp) in system one, and SD 3100 HV (no preamp) in system 2. But, I’m using the Simaudio North 761 amp in system 1 and like it very much. I did audition the 761 amp vs the 861 amp directly. Yes, the 800 series is better, but they’re closer than many would suspect - the larger amp being more “effortless”. 

Unfortunately, I did not audition their 791 vs 891 preamp/DAC units directly. I’m sure there are differences, but to the magnitude of the differences I can’t speak. Nevertheless, I did hear the 791 with the 761 and thought it was very good on both an absolute and relative basis. As I stated earlier - yes you can do better. But it’ll cost you in time, effort and certainly in money. I like my DACs better, but they are also a price point up. (So I make sure I tell myself they’re better!).

Sorry I can’t be more helpful.

I'm in the separates camp, technology moves so fast on the digital side that I want that flexibility to replace a single component if I wish. Here's a sample of what you could do for $25,000

(1) Preamp - Aric Audio Motherlode II preamp $5,750 (RCA only) or Motherlode XL $6,875 (Upgraded parts - RCA and XLR), or Don Sachs/Lynn Olson Raven preamp $6,395, Backert Labs Rhumba Extreme 1.4 $8,500

(2) Streamer - Aurender N200 $6,700 or N20 $13,400, or Lumin U2 $6,000

(3) DAC - Denafrips Terminator 15th $6,100, T+A DAC200 $7,500, Berkeley Audio Design Alpha DAC Series 3 $11,000, Weiss DAC 204 $3,800, or Mola Mola Tambaqui $14,000

(4) Keep the Moon Audio 861 amplifier

Moon 891 doesn’t use newer technology than Chord DAVE. It uses different technology. 
Moon uses off the shelf chips in their DACs while Chord DACs are FPGA. 
What is 891 primarily? Is it a DAC with streamer and preamplifier sections? Or is it a preamplifier with a built in DAC and streamer sections? You have to know the answer to this question. Call SimAudio. 
 

If you keep your McIntosh preamp adding Lumin/DAVE combo could actually give you good results. Using DAVE’s preamp section could be OK but I suspect it might be too direct sounding with 891 and Focals. Try it.
