Hi will i get much improvement over my current denon avr 1910 to yamaha v673? i want to upgrade cause of the 3d tv i got. but in terms of sound quality is it a downgrade? i mean the denon has better room correction over the yamaha? please recommend what i should do and is this a correct derision im making. bare in mind i have 350 quid budget and yamaha seemed perfect. im pairing them with my monitor audio vectors by the way.
