I was afraid you would ask that lol. I am not good at describing what i hear but i do know that its not an important feature as far as av receiver makers are concerned and moving to a separate unit was a huge improvement in the sound reproduction chain. Once i got back into vinyl i started hanging at www.vinylengine.com
, the info there is overwhelming and lots of guys who are absolute experts on everything vinyl.
BTW i though you had a denon receiver. I have a denon avr 3311ci and a Yamaha aventage RX=A1000 and neither has a decent phone stage,but hey give it try and then you will have a baseline for an upgrade.
