Pulled the trigger on a Moon 861! Hope it pairs well on my Focals

No. Had the 330a though. It was transparent but never harsh. I have a lot of doubts about the new moon north being colored and warm in any way. You don’t want this level of amplifier to color and warm things. Expect it to be refined and present a super clear view of what’s in the source. 

I am interested in you conclusions about the equipment pairing. I have a pair of Moon 880M's & am in need of new speakers. Focals are on the short list.

I have the 700i integrated and it loves my Sopra 2’s. Same tweeters you have. Should be a great pairing for you!,

I just got it hooked up to my McIntosh C12000 preamp and the Eversolo z8 streamer/dac. I have to say, compare to my Luxman 595 class A amp it sounds thin. My luxman 595, although on the bright side, sounded way fuller and even more holographic.

Compared to the what I heard in the audio store (McIntosh C12000 preamp,  DynAudio Contour Legacy towers and the DAC from Moon streamer(not sure if it was the 891 or 791) there is hardly any bass at all.

The Moon instructions say that ’The performance of this device will continue to improve during the first 100 hours of listening.’... is that why? Will it be that significant? 

Typically the sound will change a lot... being less trebly and more natural... often takes a lot more than 100 hours. 

I'm not sure why, but many companies are shy about documenting the  long burn in... even through it is required. My Audio Research gear took 600 hours to stabilize and even after that there was very slight improvements over the next 400. I burned in three of the same amps... and it followed exactly the same pattern.

I’d run it 24 x 7 for a couple weeks.
