andy2Thank You for providing your expertise as well. Agreed, amp design as it addresses feedback vs no-feedback is pivotal for our speakers. I try nt to get too tied up in the manufacturer specs as well. Reading across other Audio forum threads, other Thiel owners are enjoying some of the lesser known power amps and/or integrated amps with success. Along the lines of designers not citing 2 ohm power ratings, I also find, peak current delivery in amperes (A) not reported. John Atkinson of Stereophile fame and Paul Miller of HiFi News & Record Review fame do a pretty good job of reporting pertinent figures/ratings as discussed here.
Happy Listening!
