Thiel 3.6 s and amplifier choices


I recently purchased Thiel 3.6's. Currently driving them with an Aragon 4004 Mark II. Other equip is Arcam FMJ23 Cd, VPI TNT, and Krell KRSII preamp, FMS Grey cables and old Audioquest Interconnects. Looking for suggestions on amplifier as I think there is a lot more to be had out of these speakers. Balance is slightly tipped up due to mid bass leanness but they do so many things right. Any thoughts.

I have the Thiel CS6's and run them with a Krell FPB-300. The Thiels are so much faster, cleaner, and tighter than a PS Audio 200 (?) Delta I was driving them with. I think the more power, the more Thiels come to life. They are probably a 4 ohm load also which is a consideration. I would also go to an amp that will take a balanced interconnect.
I once owned 3.6s and loved them. I made a huge mistake in selling them. The main requirement is a fairly powerful high current amplifier that will comfortably handle a 2 to 3 ohm load. Thiel often recommends Classe, though I personally have never heard the conbination. Krell would also be an excellent choice as noted above. Before making a final decision, you should speak directly with the amplifier manufacturer and obtain definite information about the ability of their product to drive such a difficult load.
I had the Thiel 3.6's for 3 years. I chased every possible tweek, from interconnects, speaker cables, to cones, supports, etc. I never could get them to really sing until I replaced my Levinson 27.5 with a Levinson 332. The difference really made me look at all the time I had wasted chasing the holy grail for good sound with upgrades that brought be no closer to what I was looking for. Looking back now, the higher power is an absolute must with the 3.6's if you really want them to sing.
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.

You've Got To Believe Me on the Krell matching for the cs3.6's.............

Check this idea out: $1750.00 for this KSA-150 stereo amp now and add another one a little later when budget permitts,,,,send both to Krell and get back the awesome "MDA-300" monoblocks....300 watts/8ohm--600watts/4ohm--1200watts/2ohm--2400watts/1ohm.
//I'm looking for another KSA-250 to do this with for the MDA-500's!!!!!
