I've since bought a Mason Definition (alloy) for half the price of the Enigma and couldn't be happier - the attention to detail and the standard of finish are exemplary and it beats the Enigma hands down on every count. Mason are working on a titanium version, the Aspect, with a very slightly tweaked geometry for long distance comfort, available soon - I've been told the framest will be £3k. The finish is bead blasted, the same as the Ti Bokeh they are now producing. Mason say this stress relieves the metal but I think it does make for a rather less robust finish than brushed, which can have marks polished out quite easily. I could be persuaded though! All their frames have multi-ports for a myriad of internal cabling options, again something the Enigma doesn't - ugly zip ties holding external cables on a high end frame is not a good look. As for the ride of the Mason, to be honest I don't perceive much difference in the comfort level between the Van Nicholas and the Mason - on rough tarmac the VN probably edges it but only just ...
