I can only tell you from my own system that the CS3.6's can be tipped up in sound and harsh at times until the final combo came into place.(6 pre-amp / 7 amps later,ranging from Adcom up to Levinson,Rowland and Krell)Also cabling will make a huge difference with them.No matter what the price tag was the final combo ended up being the early 90's Krell gear(used).Since you already have the KRSII my advise would be to listen to the Great old KSA-150 or 250.I'm running a KSP-7b pre and KSA-150 for light listening and drop in the KSA-250 for the fun nights with my fellow musicians.Cabling is all MIT....and I got to tell this is the last "wanting" of anything new for me.Besides,all the money that was budgeted for new gear allowed me to buy mutiple amps and good cabling and even allowed me to have 2 dacs for different types of music....Thiels love power in the form of class-A and the older KSA series before the days of slide biasing where much better for the Thiels...I've tried the newer amps and was let down to a degree because of the huge cost to improvement factors.....e-mail me if you want get a few more ideas.
