Some stuff mostly useful to me
You are probably looking after the: spinorama gallery.
It is a collection of loudspeakers measurements. They can help you to make an educated decision when you want to purchase a speaker. Price and quality are very loosely related. I do not have specific recommendations but I would buy for myself:
Any bookshelves at the top of this list is outstanding.
Any floorstanders at the top of this list is outstanding.
Some brands sell high quality speakers in a consistent manner: Gelenec, Kali, Neumann, KEF, Revel, Kii, Dutch & Dutch, Ascend Acoustics, Buchardt Audio, etc New brands are also doing outstanding speakers: Mesanovic, March Audio, GGNTK, AsciLab, MoFi or SunAudio, etc
Their is also a lot of crap out there, spend some time looking at spinorama.org to get data and pointers to original reviews. It is worth having a look. Why buy a crappy one when you can have a better one for cheaper? There is enough choice among the good ones.
