Congratulations! I really like my Seduction too. For what it's worth, I waited to long to upgrade to C4S (about 5 years). Every time I went to pull it out of my system, I would sit down to get a baseline listen, and get up 4 hours later to go to bed. So do yourself a favor, listen to it for a little longer, then do the C4S, it's really a big step up. Enjoy.
