Is there any chance we could instead talk about "Vital hi Fi accessories that don't cost all that much"? I found it an interesting and useful topic...
Sure:
* A bottle of your favourite tipple
* Spotify (my favourite for music discovery, allows me to have offline playlists on my phone, £10 a month)
* Some sort of damping, like panels, in between the speakers; not having your gear in between the speakers
* A nice big rug if on a hard floor
* Having your sofa & chairs positioned so your speakers are firing across the room into them
