Time For a CD Player Upgrade

I've been using a Rega Saturn Mk 2.  I recently upgraded my turntable to the Mark Levinson 5105 w/ the Ortofon Quintet Black S.  In comparison my CD's are sounding overly bright.   Any thoughts on a comparable upgrade to my CD listening?  My budget is about $4000-5000, new or used.  The Hegel Viking looks interesting.  Any recommendation for an upgrade will be appreciated.
