Please recommend a PreAmp for my 5.1 home theatre system


I am putting together a system - so far have Krell Chorus 5200 for the Amp, and Focal Sopra No 2 speakers, along with Sopra center and Aria rear channels.  Samsung TV mid range M series.  Can you suggest a nice preAmp to work well for this system.  Budget 4 k tops.   Thanks!

In my HT system I use an Oppo UDP-205 to do the processing, feeding the fixed analog 5.1 output into a Krell HTS 7.1. Audio processing in the Oppo is superb and the Krell is just acting as a glorified 5.1 volume control. Works perfectly for me and the cost of a new Oppo UDP-205 and used Krell HTS 7.1 is about half your budget.
