I have a Rotel pre/power set up and Dynaudio 42 speakers all round. Perhaps oddly here, I'm not a movie fan - music is my thing. I enjoy my limited selection of SACD/DVDA multi channel recordings and also "rediscovering" my (substantial!) music collection using various surround modes. I'm really not a big bass fan - and usually don't want to shake the walls as my 2 littl'uns are tucked up in the room above my listening room. However, because I'm an incurable hi-fi experimenter, I wonder whether my listening experience would in any way be enhanced by the addition of a sub?
