music definitely takes on a different flavour when comparing the airy and lush sound of speakers versus the intensely detailed headphone experience.
i try to listen to my favourite albums both ways to get a feel for them. i bought my subwoofer used for $30 and it might be for PA systems since it's about the size of a mini fridge, so i can create that club listening vibe... i don't worry about my neighbours, if anything they're lucky to get the sweet DUDU-DU, DUDU-DU, DUDU-DU, DUDU-DU, DUDU-DU, DUDU-DU sounds thumping through the walls.
