Thiel cs2.3

it is the one titled something about why he started his speaker company

Here you go:

 I'm not sure why he thinks it's a rant, or how starting his speaker company is going to change things. 
 His points are right on target. And he gives a fair appraisal of the virtues of some of the renowned speakers that fall into the category of low impedance loads. He's correct that the standard spec has changed, and that it is now more complicated for the consumer.
 On the other hand the current spec is more accurate as speakers have typically never had a static impedance, and it really isn't too difficult for the consumer to calculate what amplification is appropriate so long as they know the minimum impedance. And while it's true that amplifiers tend to distort less into higher impedances, it's also true that amps and speakers prefer to work with more linear impedances, and that can be done by lowering the impedance but not by raising it. Furthermore, amplifiers that double down, or halve up with impedance do so with concurrent sensitivity changes, and therefore are better at maintaining frequency linearity. Also lower impedances are more immune to noise infiltration. Originally replacing larger speakers with smaller ones and replacing less powerful amps with more powerful amps allowed for more domestic acceptance of hifi. Now with home theatre and surround sound it's even appreciated more.   

I would have thought Coda would be a good match.  Pick the model according to the number of watts you want and the percentage of them in class A.

^Good choice, but it appears as is often the case Class A output decreases as power increases into lower impedances.

OP
I have been driving my CS 2.3 using: Pass XP-22 > Pass X-250.8  with absolutely wonderful results. I upgraded my electronics last year and these Thiels have never sounded so good in the 20 yrs I have owned them. Phenomenal bass control with great imaging and soundstage. Not bright at all with the Pass electronics. They are good speakers if you have an amp capable of driving them with authority. The Pass X-350.8 would also be a great match.
