what is a right IC for my current setup

I am using a Techincs A-10 as my CD player, goes directly to my Krell pwr-amp, I use an old Cardas between the pwr-amp and the B&W 801. ( previously I was using an Audible Illusion L1 as the preamp). I am thinking of upgrading my IC between the DVD player and the pwr-amp. Would a Cardas Neutral reference or a Audience AU-24 a good match. I am thinking of either changind the DVD player to a SACD player.
