I have heard the klimaxes and akurates and various others of the modern range. Like many speakers that are readily available in the uk they are (imo) just 'ok'. You can do much much better elsewhere, especially if you are looking for a sound which transcends hifi ... e.g. ATC, Avalon, Zu, Vanderstein, Revel, Wilson, Magico, green mountain audio, SF, living voice.
I have to completely agree on the Nexus as well. I think it was Grahams where I first had the pleasure. Probably the most revolting loudspeaker I have ever experienced.
