I am certainly not an expert, but I have noticed profound imaging differences between digital and analogue. Analogue is (for the most part) deeper and more spacious in its effects. It sounds like your room is posing reflections off of surfaces that only the deep analogue imaging gets at. I have noticed this too, betwen my Meridian 24 bit CD and my Linn LP12, both are very good, but sound very very different. If I were you before I spent any $$$ I would simply play around with speaker placement and the furniture in the room, including pictures on the wall (beware of glass!)
