I've heard the JM Lab Chorus 714S and they were very good at less than £400. Have heard the V version and they were, from memory, equally as good, but the RRP had jumped to around £700. Whether the price makes them worth it or not is another question (they can be purchased for about £400 from certain outlets).
Nevertheless, the 714Vs are still in my top 5 floorstanding speakers around that sort of price bracket.
