Amp recommendation to drive Thiel 3.6 speakers


Hello everyone,
My first post here. I''l get right to the point.
I am looking for recommendations for suitable power amp monoblocks to drive a pair of Thiel 3.6 that I have had for 20 years, and which I intend to keep. Let me describe my current system.
Speakers: Thiel; 3.6
Power amps: Manley 250 classic monoblocks (tube)
Pre-amp: Audio Research Reference (tube)
Phono-pre: Audio Research Reference 2 SE (tube)
Turntable: VPI/SME, and Linn LP12
Digital: Audio Research CD3

I am looking for recommendations to replace the Manleys. From what I know, the Thiels are a difficult load.
Thanks in advance

In my opinion, you are better off biamping these speakers. As these speakers are not coming with double binding posts, you would have to add these. Drive the mids and tweeter with one channel, and the woofer with the other channel. Any pair of decent amps will be able to give good results and likely much cheaper then the alternatives.
Even if bi-amped both amps would need to do most of their work below 4 Ohms. And with their 1st order crossovers larger than usual overlap (compared to other crossover slopes), would suggest using identical amps would be more appropriate as well. 
Not sure I’d spend upwards of $10k to power 3.6es (and I do think they’re great speakers), but what do I know?  The Clayton Audio M200s will drive the hell out of ’em but not sure how they’d fare on the WAF scale.  The S100 might be a little more palatable.  Thiel used to show with McCormack a lot back in the day, and there’s a DNA-500 listed on US Audio Mart for $3300.  Or, somebody just listed a pair of DNA-1 monoblocks up on eBay you could buy and have Steve do full upgrades and still be closer to $5k all in.  Personally I’d do the latter.  FWIW, and best of luck.
