[quote="bottleneck, post: 693120"]I don't know.. I think I'm just hungry! :D NB, I've just googled for a giggle, and it appears the Kudos C10/C20 use the Seas Crescendo tweeter, which is a slightly dearer but visually very similar driver to the millenium. NB, Markus it was the C10 I was thinking of, thanks.[/QUOTE] Crescendo is the new top dog in Seas tweeter line up. About £200 vs. £150 for the Millenium. Slightly reworked motor means lower distortion but the same moving parts also mean a very similar sound overall. If your like domes then these two are near the top of the pile but for me not much beats a ribbon for all those hifi virtue's. The RAAL 140-15d(approx £270) in particular is possibly the best HF driver I've heard or used (so far). Beautiful sound that makes my old Scanspeak R2904-7000 sound like its broke.
