Best possible separates for Thiel CS 3.7

Hi guys, here's the latest news regarding my quest for the ultimate Thiel CS 3.7 rig.On oct 24 i will be demoeing in Geneva at Dartzeel factory NHB-18NS + NHB-108 model 2 combo.The next day i will be in Zurich to demo Aries Cerat Impera ll preamp + Diana Forte stereo amp driving a pair of Thiel CS 3.7s.The AC Kassandra Ref DAC will also be in this rig.In the afternoon we will go listen 2 other rigs also with Aries Cerat pre-power and some KR Audio stereo amp driving nice horns.There is one last ultimate pre-power combo that i would like to demo on my Thiels : CH Precision L1+X1+M1 stereo.As you can see my budget has raised quite a bit but this will be for me a once in a life time system.My digital front end will be the brand new Totaldac d1-Twelve mk2 + d1-server.

My question of the day is if you had a budget of 50K to drop in a pre-power combo to drive a pair of Thiel CS 3.7 what would be your top 3 favorite choices

You need to look at the impedance/-phase graph to make an informed decision.
This speaker cries out for solid state with plenty of current, which to me says big muscle amps amps with bi-polar (bjt) output stages.
EG: Gryphon, Krell, D’Agostiono, ect ect .
(My choice would be a Gryphon Antillion Evo with user adjustable Class-A bias points while playing music)

• " CS3.7’s impedance remains between 2 and 3 ohms over much of the audioband (fig.1), and that there is a demanding combination of 3.8 ohms and –40° capacitive phase angle at 60Hz. Thiel specifies the impedance being nominally 4 ohms, with a minimum of 2.8 ohms. I actually found the minimum impedance to be 2.4 ohms at 125Hz. The difference between 2.8 and 2.4 ohms is academic, either mandating use of an amplifier that has no problem delivering high currents."

Gryphon Antileon Evo would be a very good choice with the Pandora preamp.I have demoed this combo driving Rockport Atria V2.This amp has an impressive grip on just about any speakers.

Bryston 7B cubed

As good as Bryston is it's not in the same league as Gryphon, CH Precision, Ypsilon and Aries Cerat to name a few.
