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!

Thanks for some great responses!  The OPPO idea is intriguing.  Didnt realize that a Blu Ray could double duty as a PreAmp.
you shouldn't use the Oppo to do the volume control duties... that said the Oppo205 is great for everything else.. I have one and had it modded (Modwright).. for music - analog out to HT bypass and for movies HDMI out..  Foundation perfect match for your amp
There is no problem using the Oppo's volume control. Once upon a time digital volume ocntrols were not a good idea as it cost you bit depth. These days, with internal 32 bit processing, this no longer applies. See here for a presentation by Sabre: http://images.computeraudiophile.com/graphics/2015/1216/digital-vs-analog-volume-control.pdf
