@jon_5912 Stereophile measured the CS3.7 impedance as low as 2.2 Ohm, so even the more powerful AX-5 might be a marginal match for big rooms or loud-preferring listeners. Still, I'm surprised the AX-7 didn't at least deliver good sound at moderate SPLs.

Wes Phillips used several amps for his CS2.4 testing including a vintage Fisher measured at 6W into 4 Ohm!

. . . while not my first choice for the job, did not acquit itself too badly.

But for his review of the CS3.7 he used the Ayre MX-R and Musical Fidelity Nu Vista (480w into 4 Ohm).

Thanks Tom.

Just to be clear, when you write: <i>"38" ear height is design target."</i>
Does that design target assume the speaker is on spikes or not?

If I may:
that’s the ear hieght
(+/-?) of the typical seated listening position.

Thanks jafant for finding and posting contact information for Rob Gillum's
Thiel speaker service company. My mint condition 1986 Thiel CS2's  continue to please to no end. Come the day they need attention I know who to call...:) 

38" ear height is design target.

I imagine there must also be a target distance to the listener, as well, that corresponds to the 38". In Soundstage’s measurements of the CS2.4, they measured at 2 m which is their standard. But the height was a manufacturer-specified 30" from the bottom of the speaker (presumably w/o spikes).
