Best bookshelf speakers


Hi all,

I'm looking to buy a pair of good bookshelf speakers and since a lot of you here seems to know about speakers much more then me, I figured I'd ask for advice.

Here are the parameters I'm working with / looking for:

- The room is about 1200 cu/ft
- Looking for great performance at low volume
- Rich timbre
- Rich, warm bass
- Natural highs (not metallic-sounding)
- Low frequency range in around 40Hz (preferably 30Hz, but I know, there are hardly any in this range at my price point)
- $500 - $700, new or used

So far I am considering the following options (in no particular order):

- KEF Q350
- Dali Zensor 3
- Canton Chrono 503.2
Wharfedale Diamond 225

So my questions are:

1) From my list of 4, which would be your choice?
2) What other bookshelf speaker would you add to the list that fir my parameters?

Any thoughts are appreciated

Wharfedale Denton, to some it's even more listenable than the famous KEF LS50, with your budget the Denton could be the last best speakers you will ever need, prepare a better clean power amp for it.
I think there is a lot of good quality parts that go into the Focal line of speakers and they sound very good. Good prices are available on new and referbished units.
+1 lak. The Focal Chorus 706 are now sold new for $550. I have a pair in a secondary system. They fit your room size well. Have a very articulate midrange and treble, doesn't go as low as you are looking for ( at your budget this is expecting too much), however very satisfactory bass for a small room. Image and soundstage well. 

Dali Zensor 3 all the wayyyy!
 They need a LOT of running in for the bass to come alive..
There is a pair of LSA 1 monitors in Black Ash for sale here that are a SCREAMING deal...
