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.
