Been playing about with my shiny new Yamaha receiver for the past 24 hours and really like the DSP programmes. However, in conversation with others, I realise they're not popular with everyone. As I have a small lounge, I've been particularly impressed with the 'Spectacle' programme on my receiver which I combine with the Matrix 6.1 mode (which creates a virtual rear speaker for 5.1 input). The 'Spectacle' program gives me the feeling of a really wide soundfield (supposedly comparable to a 70mm movie theatre, according to the manual) and really enhances the existing soundtrack IMO. So - do you love DSP programmes or do you hate them and prefer to stick to a 'pure' reproduction of the soundtrack? If you love them, what DSP programmes do you use?
