I currently use a Yamaha RXV350 with a Pioneer 370 DVD player for both movies and music. While this combination serves me perfectly well for watching movies, it's not much good for serious music listening. I have limited space & budget (£150ish) but am keen to improve music performance as much as possible. 5-channel stereo is the only sound mode which is listenable, with 2-channel sounding considerably quieter even when I try to crank up the amp. (My front speakers are Tannoy Mercury M1s). In DD/DTS/DSP modes, all of the speakers operate properly so I don't think it's a problem with wiring. I suppose it's just a limitation of a budget amp? How much difference would a DAC make to this setup? I'm guessing it won't affect the volume but don't know much about it tbh. I realise these things are subjective but for all I know the difference is like a 500% improvement! Thanks in advance for any tips/advice!
