Dumb question......why do you need a preamp?

Most AVR’s and Integrated Amps just have way too much under the hood driven usually by an insufficient power supply. Myself I found I’ve been able to achieve the most satisfying sound to my ears utilizing a dedicated unit with each having it’s own power supply at each stage of my set up.  After years of the AVR / Integrated Game I’ve come to the conclusion performance is sacrificed when you settle for versatility.    

If you have a DAC like Audio Analogue's that has an analog volume control, you don't need a preamp. 

I have a vinyl rig and send the signal from my phono preamp to my DAC and out to my amps. No preamp.

Preamps are merely expensive volume controls. 

I have not a clue what most of you said, but I thank you anyway.

There must be a reason why you boutan integrated to begin with, and if you're not satisfied with the sound but want the convenience, get a better one. There are literally hundreds of the out there at all price levels.
