Thiel Owners

Listening to some speakers at a dealer (a former Thiel dealer) recently, I mentioned that I've owned Thiel 3.6s for 21 years and recently had my amps updated, upon which he replied that Thiels are real "amp killers."  The dealer stated that since Thiel speakers are so difficult to drive, they "eat-up amps."
I've never heard that comment previously, so am wondering if there's any way a demanding speaker can have a negative affect on an amp's life.
Facts (rather than opinions) would be appreciated.
Thanks.

My pleasure. Thank You for seeing a way to make an excellent loudspeaker- Outstanding! You guys here that are on the D.I.Y side are performing an incredible service for many owners. Very cool and sharp minds. I believe in modifications and the modders that make it happen.

Happy Listening!

interesting query and percentage factors for the Panel to ponder.
Room acoustics may be the most adjustable factor as some of you guys have a naturally great -sounding space (low percentage). While others, have an inherently unforgiving acoustical space (higher percentage).
The same train of thought can be applied to dealers/retailers. IME, I must give props to The Listening Room in Baltimore MD. The retail space had excellent sounding rooms without any additional acoustical treatments (all rooms were contractor carpeted).

Happy Listening!
