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

Ya, I have the volume up 90% on my phone. This setup is only for breaking in the amp. I don't want to put 100 hours on the Macintosh amp if I'm not really listening. I'm going to try playing the amp on low volume while I sleep at night to try to get 8 hours a night on it.

Just keep it on 24/7 and play music thru it as much as you can. It’s going to be fine when your preamp is back in. 
what do you normally use as a source to feed the dac?

The ever solo z8 has a Bluetooth connection to my phone. So I play music on my phone and it goes through the eversolo DAC. Normally I would have the ever solo connected to the Macintosh C12000 preamp. Is that what you mean by use as a source to feed the dac?

Yes, you are using the Eversolo as a preamp...that it why your system is not sounding good. All should be good when you put your Mac back in. 

@dman777 yes. Bluetooth is a noisy and low resolution method of sending music to your DAC. You’ve invested significantly in your components. Get a proper streamer and connect it to the DAC using a good USB cable. Don’t use Bluetooth man. It sucks.
