Thiel Owners

@beetlemania, I don't think it did too badly at low volumes but I cranked it up pretty quickly to see how it would do with something loud and meaty and it wasn't up to it. I was at the dealer and I didn't spend a whole lot of time listening for subtle differences.  I find that it takes me a long time to make up my mind about whether something is different, better or worse and I can't really do it at the dealer.  I listen to make sure it's about what I want and then take it home and usually need weeks to make up my mind 100%.  

I'm also a believer in having too much power.  It might be my imagination but I think having what would seem to be way more power than necessary makes a difference.  My current setup has 2 200 watts@8ohm/channel amplifiers running bridged mono.  I've had this setup for 10 years or so and I prefer it.  

Much of the spike length was intended for carpet height piercing.

The outriggers and spikes on my CS2.4SE raise the speakers a good 2". I think these spikes are a bit longer compared to the standard version. About one-half of my floor is slab and tile with a hand-woven rug under the speakers. I use 1.5 x 2 x 0.25" wood blocks under the spikes to protect the rug. The other half, which includes my listening seat, has wall-to-wall on top of the slab. I find the spikes to improve the SQ at least a little altho' not sure how much is due to listening height v. better coupling to the floor.

limited to perhaps 200 Hz and above.

Yes, Thiel's graphs are truncated at 200 cycles:

Those CS2.3 measurements are superb!

For the bass, I think Stereophile's nearfield technique fills in the gap nicely.

That's one reason I haven't used mine.  Even raising my speakers on shorter footers has changed the sound in a way I don't care for.
