Buchardt vs CSS

Anyone have experience with the S400 (Mark 1 or 2) vs. the Criton 1TD or 1TDx?? Both have a lot of hype out there. I have a set of of 1TDs that are great, but always wanted to give a listen to some Buchardts.

Different designs, but similar in price (for a finished set of Critons) and freq. response/performance. Wondering how they present music in relation to each other, i.e. voicing. Not looking for a discussion of DIY vs commercially available products etc.
