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

So far I have about 10 hours on it. I am starting to hear the beauty come out of it which is really nice. 

One thing that bothers me, though, is.... currently I have just the Eversolo Z8 DAC on it. I have the McIntosh disconnected while I burn 100 hours (in about 2 weeks). 

I have the Eversolo at 70% volume and I feel like it's not as loud as I would like it to be. I can go to 80% but it gets a bit to boomy and tiny bit muddy. For instance, my Luxman 595 is super loud at 60% volume, I can't go louder without blowing the speakers. Will the Moon amp also get louder as the hours burn in? 

So, you are using your DAC straight into the amp... that is the issue. It is the input to your amp that determines the volume you get out. Your preamp should provide the input voltage (I think that is the parameter). An amp does not vary its amplification... that is what the preamp does... unless your are using your DAC as a preamp as w'll (unlikely to sound great). Should sound great with lots of volume when you put your Mac back in. 

@dman777 matter of sensitivity and gain matching. Don’t worry about it for now. Break it in first. 

Changing an amplifier is a major impact on the system. It’s got to be matched with speakers as well as with upstream components and room. Don’t exclude the possibility that you will need to readjust speaker placement. But don’t do anything at all until you have a minimum of 200hrs on it or you will be chasing ghosts. 
Good luck!

I am using balanced inputs from the Eversolo to the Moon Audio amp. Would that mean I am using the Eversolo as a preamp? I use the Eversolo app to stream music from my phone bluetooth.  Is that ok that I have this particular setup or would could there be a mismatch in voltage with the amp that would cause the amp stress? 

If you are using Bluetooth then the volume on your phone needs to be raised. 
it’s fine for breaking in the amp but why not use the right setup?
