You already know through your own personal past experience with the 225 and the rave reviews that continue to come in world wide that the Job is a no brainer. Congratulations on your worth while investment!

Now 6moons speaks highly of the integrated dac and comparing it to the Metrum Hex my Job INTegrated is on it's way! 

What I don't get is, Srajean said when fed a digital signal, the INTegrated is just as good as a Metrum Hex, passive pre, and the 225. In some ways, better. 
I have the Hex, Tortuga LDR passive and the 225.
Now, I'm no scientist or engineer, but common sense tells me you can't beat the laws of physics. How can a 3 in 1 which shares the same power supply for everything, be better than the 3 pieces mentioned? Ok, shorter signal paths and other benefits, etc. 
It just doesn't make sense.
Actually hoping Srajean chimes in here, which he has done in the past.
