I'm using the avr 1905 strictly as a processor. I have music fidelity A class amps (6) to run my home cinema. Using B&W speakers 4 + subW. I'm fiding the dialogue to be average. Considering my equipment, I'm some what suprised. Is there an aspect on the avr 1905, to improve dialogue capabilities? Seems to create a lot of bass when there is dialogue.
