Superfi has a discount going on on the Revel Concerta M16. Only white colour though. I called up to get confirmation that these were the Concerta2's and were new. Good on both Counts.
As @DemHotDeals highlighted EXTRA10 would get you another 10% off the price of the speakers, taking the price down to £522.
This is one of the few speakers under £1000 rated rather favourably by both What Hifi and ASR.
