IC suggestions between Linn Ikemi CDP and Plinius 8150

I currently use HT Truthlinks between a Linn Ikemi CDP and Plinius 8150 integrated, and HT Pro 9s to B&W Matrix 803s. Any recommendations for a better IC in the $300 - 400 price range (used is OK - .5 or 1m RCA). I like smooth but looking for improved transparency and detail.
Thanks, Joel
