Just installed a bluesound node 2i , quality not so good

I was held hostage by a group of audio terrorists,and they forced me to use a DAC. It wasn’t like I had a choice! 

    Seriously, for me,I ran node products for a couple of years through the analog outs. I was pleased with the sound. I just wanted to see if I get better sound. Just like any other facet of this hobby. 

+1rocray!
I  was wondering who was holding the gun to whose head to "make" them use a DAC.
Op asked and was given opinions, nothing more.

I have I have bluesound wired to avr now, can I bypass avr and direct wire to amp? Can amp have two sources of input? Not sure it would be smart to do this?

I am being held hostage by my speakers holding out until they reach their full potential.  Captivity is challenging, expensive, and frustrating due to a lack of clarity in the marketplace relating to a vast maze of complex components.  This forum has proven to be of great value.

Would a used McIntosh d150 dac be a good choice to go with the bluesound 2i?
